Best Things to Do in Big Island of Hawaii (2026)

The road descends through layers of geological time, dropping nearly 3,700 feet from the rim of Kilauea caldera to the edge of the Pacific Ocean. Chain of Craters Road cuts through the heart of Hawaii Volcanoes National Park on the Big Island, tracing a route across hardened lava fields that represent centuries of eruption, collapse, and resurfacing. The landscape shifts from forested highland to stark, moonlike plains of pahoehoe lava, interrupted by pit craters that open without warning beside the road.

Along the 19-mile route, a series of pit craters dot the roadside, each offering a different view into the volcanic geology of the island. Petroglyphs etched into ancient lava can be seen at a marked site along the way. At road’s end, the ocean entry area has historically been a dramatic focal point, though the exact conditions change as lava activity shifts over time. Interpretive signs throughout explain the ongoing interplay between eruption cycles and land formation.

The drive takes anywhere from one to several hours depending on how many stops are made; most visitors allow at least half a day. Starting in the morning avoids afternoon heat on the exposed lower lava fields, where there is little shade and temperatures can be considerably warmer than at the park entrance elevation. The road is paved and suitable for standard vehicles, though visitors should carry water, sun protection, and closed-toe shoes for any short hikes.

Within Hawaii Volcanoes National Park, Chain of Craters Road is distinct from the caldera-focused Crater Rim Drive in that it takes visitors down to sea level, offering a perspective on the sheer scale of lava production on the island’s lower flanks. The combination of geological drama and sweeping ocean views at the bottom makes it one of the most complete drives in the national park system.

The road loops around the rim of one of the world’s most active volcanic calderas, passing steam vents, sulfur banks, and viewpoints over a crater that has been in near-continuous eruption for decades. Crater Rim Drive in Hawaii Volcanoes National Park circles the Kilauea caldera on the Big Island, offering a sequence of geological spectacles within a few miles of paved road. The landscape shifts from dense rainforest on the windward side to barren, steaming desert on the leeward — a transition that happens over just a few minutes of driving.

Portions of the drive have been closed and reopened at various times depending on volcanic activity and hazardous gas levels, so the accessible sections change over time. When open, key stops include the Kilauea Overlook for caldera views, the Devastation Trail through a cinder field, and the Thurston Lava Tube — a walk-through tunnel formed by a lava flow whose outer shell hardened while the interior kept moving. The caldera itself, home to Halemaumau Crater, has been one of the most closely watched volcanic features in the Pacific.

Morning hours offer the clearest air and best light for photography before gases and clouds build over the caldera. The drive itself takes one to two hours with stops, but most visitors extend their time considerably by walking short trails along the way. Volcanic emissions can affect visibility and air quality — visitors with respiratory sensitivities should check conditions before driving near active emission areas. The park entrance fee covers access to the entire drive.

Within Hawaii Volcanoes National Park, Crater Rim Drive serves as the central organizing route — the axis from which most other park experiences radiate. It provides context for the broader volcanic system that Chain of Craters Road descends, and it is where the park’s geology becomes most immediately legible to visitors with limited time.

In 1959, a months-long eruption filled this crater with a lake of molten lava reaching depths of over 400 feet, then drained almost overnight back into the earth, leaving behind a solidified floor that visitors can now walk across. Kilauea Iki Crater sits adjacent to the main Kilauea caldera in Hawaii Volcanoes National Park, and the four-mile loop trail descending into it is one of the most geologically immediate hikes on the Big Island. The contrast between the forested rim and the barren, steaming floor below makes the 1959 event tangible in a way that overlook photographs cannot convey.

The trail begins at the Kilauea Iki Overlook, descends through native ohia lehua forest, then drops onto the crater floor where hikers walk across hardened pahoehoe lava marked by cairns. Steam vents rise from cracks in places, a reminder that the ground beneath remains warm. The crater walls rise steeply on all sides, and the high-lava mark from the 1959 lake is visible as a distinct line on the interior cliffs. The return loop climbs back through forest on the opposite rim before returning to the trailhead.

The full loop takes two to three hours at a moderate pace. Sturdy footwear is essential as the lava surface is uneven. The trail suits reasonably fit hikers but is not recommended for those with knee or ankle issues. Morning starts are advisable before afternoon clouds reduce crater visibility. The trailhead parking area fills by mid-morning on busy days; the park shuttle provides an alternative.

Within Hawaii Volcanoes National Park, Kilauea Iki offers something drive-accessible overlooks cannot — standing inside a crater that was an active lava lake within living memory. It gives the volcanic landscape a human scale that transforms abstract geology into something genuinely felt underfoot.

The water inside Kealakekua Bay runs exceptionally clear, and through it the reef visible from a kayak or snorkel mask appears close enough to touch — an illusion of the bay’s calm, protected surface and the transparency that comes with healthy coral. This crescent of water on the Kona coast has drawn people for centuries, first as a sacred site and center of Hawaiian culture, then as the location where Captain James Cook died in February 1779 following a confrontation with islanders over a stolen boat.

The bay is designated a State Historical Park and Marine Life Conservation District, and the combination of protections has preserved both its historical associations and its underwater ecology. Spinner dolphins frequently shelter in the bay’s calmer waters, particularly in the morning hours. The snorkeling off the northern shore near the Cook Monument is considered among the best accessible reef diving on the Big Island, with high coral cover and diverse fish populations. Access by kayak or tour boat is the primary means of reaching the monument site, as the road down to the water is restricted.

Morning kayak launches from nearby put-in points or guided boat tours from Kailua-Kona offer the most reliable dolphin sightings and calmest water conditions. The bay can develop afternoon chop as trade winds strengthen. Tour operators run snorkel trips to the bay regularly; self-guided kayakers should check permit requirements before launching. Plan three to four hours including transit time for a full experience.

Among the Big Island’s coastal destinations, Kealakekua Bay carries a density of historical and ecological significance that few comparable sites can match. The juxtaposition of a functioning marine sanctuary with one of the Pacific’s most consequential historical events gives the bay a character that rewards both the naturalist and anyone curious about the contact period that transformed Hawaii.

A white obelisk stands on a lava shelf at the northern edge of Kealakekua Bay, visible from the water but reachable only by kayak, boat, or a demanding overland trail. The Captain Cook Monument marks the spot where the British explorer died in February 1779 during a confrontation with Hawaiian islanders — an event whose causes and significance historians have debated for more than two centuries, and which marked a turning point in the relationship between Hawaii and the outside world.

The monument itself is relatively modest, a stone pillar erected in the nineteenth century on land that remains, by legal arrangement, British territory. What surrounds it is far more compelling: the marine conservation district that covers Kealakekua Bay protects some of the healthiest coral reef on the Big Island’s coast, and snorkeling directly off the rock shelf near the monument places visitors above exceptionally clear water with abundant marine life. Spinner dolphins shelter in the bay regularly, particularly in morning hours before boat traffic increases.

Most visitors arrive by kayak from nearby launch points or aboard guided snorkel boats departing from Kailua-Kona. The overland trail descending from the highway above is long, steep, and exposed — suitable for experienced hikers with adequate water but not a casual option. Morning arrivals by water offer the calmest conditions and best wildlife activity. Plan three to four hours for a kayak excursion including snorkeling time at the monument site.

The combination of historical weight and ecological quality at this single location is unusual even by Hawaiian standards. Kealakekua Bay connects two of the Big Island’s defining stories — the vitality of its marine environment and the contact-era history that reshaped the islands — and the Cook Monument, modest as it appears, sits at the intersection of both.

The highway north from Hilo hugs a coastline where waterfalls drop onto the road’s edge, gulches slice through pastureland shaped by sugar plantation agriculture for over a century, and the ocean below alternates between black lava shelves and churning surf. The Hamakua Coast stretches roughly 50 miles along the Big Island’s northeastern shore, connecting Hilo to the Waipio Valley overlook and passing through landscapes that compress the island’s ecological and historical range into a single drive.

The route passes through the town of Honokaa, where plantation-era storefronts line the main street, and skirts deep gulches where streams run year-round thanks to the consistent windward rainfall. Scenic pullouts offer views of the coastline below. Akaka Falls State Park, accessible via a short detour, contains two significant waterfalls including one of the tallest in the state. The Hawaii Tropical Botanical Garden sits within a coastal valley along this route as well.

The drive from Hilo to the Waipio Valley overlook takes roughly an hour without stops, but most visitors spend three to five hours exploring pullouts and detours. The road is well-maintained and suitable for standard vehicles throughout. Rainfall is common on the Hamakua Coast regardless of season — a light jacket is worth having. Morning tends to offer clearer skies before clouds build against the mountain slopes inland.

Within the Big Island’s geography, the Hamakua Coast occupies a distinct ecological zone — wetter, greener, and more historically layered than the dry Kohala or Kona coasts on the western side. It rewards visitors who slow down and treat it as a destination in itself rather than simply the road between Hilo and the valley lookout at its northern end.

Mauna Loa rises so gradually from the ocean floor that its true scale is almost impossible to perceive from any single vantage point. Measured from its base on the seafloor, it is the largest volcano on Earth by volume, a shield built from successive lava flows into a dome that covers half the Big Island and reaches 13,679 feet above sea level. Its most recent major eruption in 2022 sent flows toward Saddle Road before pausing, a reminder that this mountain remains active on its own geological schedule.

Access to the summit area is possible via the Mauna Loa Road, which branches from Hawaii Volcanoes National Park and climbs to a trailhead at around 6,600 feet. Summit hikes are serious multi-day undertakings requiring acclimatization, cold-weather gear, and careful preparation — the summit crater sits in a zone of extreme altitude and unpredictable weather. The Mauna Loa Observatory on the northern flank has maintained continuous atmospheric CO2 measurements since 1958, producing the Keeling Curve that tracks global carbon dioxide concentrations.

Casual visitors can drive the Mauna Loa Road to the lower trailhead for views across the volcano’s broad flank and surrounding lava fields without committing to the summit climb. Weather changes rapidly at elevation and the road can close in adverse conditions. Summit attempts require planning, overnight permits, and prior experience at high altitude.

Kilauea draws more visitor attention within Hawaii Volcanoes National Park, but Mauna Loa represents something different — not spectacle but sheer scale, the quiet accumulation of mass that makes the Big Island what it is. Among the world’s large shield volcanoes, it has no equivalent that is both active and accessible to the general public.

The Kohala Coast stretches along the northwestern shore of Hawaii’s Big Island, encompassing one of the most luxurious resort corridors in the Pacific alongside ancient Hawaiian archaeological sites and some of the island’s finest beaches. Sheltered from trade wind rains by the Kohala and Mauna Kea mountains, this sun-drenched coast averages over 300 sunny days annually, making it one of the most reliably pleasant destinations in all of Hawaii.

World-class resorts including Mauna Kea Beach Hotel, Hapuna Beach Prince Hotel, and the Four Seasons Hualalai line the coast, each positioned to take advantage of stunning ocean views and calm swimming conditions. The Mauna Kea and Hapuna beach parks, both within the resort corridor, are consistently ranked among Hawaii’s best beaches for swimming and snorkeling. Petroglyphs at the Puako Petroglyph Archaeological Preserve provide a window into the ancient Hawaiian civilization that once thrived along this shore.

The Kohala Coast is at its finest from April through October when trade winds keep humidity in check and surf remains calm on the west-facing beaches. Winter months bring slightly larger surf and occasional wetter days, though the coast is sunny and warm year-round. Snorkeling, sport fishing, winter whale watching, and sea turtle encounters are among the outdoor highlights available throughout the seasons.

Accessible from Kailua-Kona Airport, which serves the entire west side of the Big Island, the Kohala Coast lies roughly 25 to 40 minutes north by car. The combination of exceptional beach quality, world-class resort amenities, and significant cultural sites makes this stretch of coastline one of Hawaii’s premier destinations for visitors seeking both relaxation and exploration.

Kohala is the oldest of the Big Island’s five volcanic regions, forming the northernmost tip of Hawaii and encompassing a landscape of dramatic contrasts that ranges from the lush, deeply carved valleys of the wet Kohala Mountains to the dry, sun-baked pastures of the south and the ancient lava fields along the coast. This historically rich region holds some of the most significant sites connected to the life of King Kamehameha I, the warrior chief who unified the Hawaiian Islands.

The Kohala region divides naturally into North Kohala and South Kohala. North Kohala centers on the historic town of Hawi and the original Kamehameha statue at Kapaau, while the Pololu Valley Lookout at the road’s end provides one of the Big Island’s most dramatic panoramas over cliffs and a black sand beach far below. South Kohala encompasses the luxury resort corridor along the Kohala Coast and its exceptional beaches. The Kohala Ditch Trail and Zipline offers adventure access to the verdant interior valleys carved by centuries of rain.

The best time to explore Kohala depends on which aspect draws you most. The coast and south Kohala are reliably dry year-round, while the north and mountain areas receive more rainfall, particularly from winter through spring. Scenic drives along Highway 270 through the north are most rewarding in clear morning conditions before afternoon clouds gather over the peaks inland.

Kohala is roughly one hour north of Kailua-Kona Airport by car, making it a logical all-day excursion that combines beach time, historical sites, small-town character in Hawi and Kapaau, and the dramatic scenery of the valley lookouts. Few regions of the Big Island pack as much geographic and cultural variety into a single day of exploration as this northern district.

Hualalai Volcano rises along the western flank of the Big Island of Hawaii, standing as one of the island’s five major shield volcanoes and the third most recently active. Unlike the dramatic lava flows associated with Kilauea, Hualalai presents a quieter face today, its slopes blanketed in coffee farms, residential neighborhoods, and the manicured grounds of Kona’s luxury resorts. The volcano last erupted in 1801, sending lava flows that reached the ocean and reshaped the coastline near what is now Kailua-Kona.

The volcano’s lower flanks offer some of the most productive agricultural land on the island, where Kona coffee is cultivated in the rich volcanic soil at elevations between 1,000 and 3,000 feet. The mist-cooled mornings and sunny afternoons create ideal growing conditions. Anchialine ponds, brackish pools connected to the ocean through underground lava tubes, dot the coastal areas near Hualalai’s base and provide habitat for rare endemic shrimp species.

The summit reaches 8,271 feet and is considered one of the volcanoes most likely to erupt again in the future, making it an area of active geological study. Access to the upper elevations is limited, as much of the land is privately held. Visitors primarily experience Hualalai from the resort corridor along Queen Kaahumanu Highway, where the volcano’s broad slopes form a dramatic backdrop to the Kohala Coast.

Visiting in the drier months between April and October allows for clearer views of the summit. The coastal areas at Hualalai’s base, including beach parks with anchialine pools, are best explored in the morning hours when winds are calm and visibility is at its best.

The Huleia River moves quietly through a valley that inspired the jungle river scenes in an early Indiana Jones film, its banks dense with hau thicket and native vegetation that the refuge has protected since its establishment in 1972. Huleia National Wildlife Refuge covers nearly 240 acres of lowland riparian habitat in the Huleia Valley just south of Lihue, providing critical nesting and foraging ground for Hawaii’s endangered waterbirds. The valley itself is one of the few places on Kauai where the full suite of native Hawaiian waterbird species can be observed in a relatively undisturbed setting.

The refuge is closed to general public entry on foot, which is precisely what keeps the habitat intact. Access is available through guided kayak tours that paddle up the river from the coast, offering close views of the shoreline vegetation and opportunities to spot the Hawaiian coot, Hawaiian moorhen, Hawaiian stilt, and Hawaiian duck — all endemic species that depend on protected wetland environments like this one. The canopy along the river creates a tunnel effect in places, and the birdlife is most active in the morning hours when the water is calm.

Kayak tours typically depart from the Nawiliwili area and last two to three hours on the water. Booking in advance is advisable, as operator capacity is limited and popular tour times fill quickly. The river is calm and suitable for paddlers of all experience levels, including beginners. Binoculars enhance the birdwatching significantly, as some species stay close to the reed beds and are easier to identify with magnification.

Within Kauai’s conservation landscape, Huleia is notable as a functioning refuge rather than a developed visitor attraction. Its restriction on foot access has allowed the riparian ecosystem to recover in ways that few accessible Hawaiian wetlands have achieved, making the guided kayak experience a genuinely rare window into protected native habitat.

The clifftop at Kilauea Point juts into the Pacific at Kauai’s northernmost tip, where the trade winds arrive uninterrupted from the open ocean and seabirds wheel in the updrafts just feet from where visitors stand. The refuge here protects one of the most accessible seabird colonies in Hawaii, with red-footed boobies, great frigatebirds, Laysan albatrosses, and wedge-tailed shearwaters nesting on the slopes below the lighthouse promontory. The combination of an active colonial nesting site and dramatic ocean scenery makes Kilauea Point one of the most rewarding wildlife stops on the North Shore.

The Daniel K. Inouye Kilauea Point Lighthouse, a historic structure dating to 1913, anchors the promontory and serves as the visual centerpiece of the refuge. The lighthouse is the focal point for ranger-led programs and provides a geographic reference point for the surrounding ocean views, which extend north without interruption to the horizon. Hawaiian monk seals occasionally haul out on the rocks below, and humpback whales pass through the offshore waters during winter months. Spinner dolphins are also spotted regularly from the bluff.

The refuge operates on limited days and hours, and access is by timed entry ticket that must be reserved in advance — walk-up availability is rare during peak months. Morning visits offer the best light for photography and the most active bird behavior. The path from the parking area to the lighthouse is paved and relatively short. Binoculars are strongly recommended for appreciating the nesting colonies on the slopes below the overlook platform.

Within Kauai’s North Shore, Kilauea Point National Wildlife Refuge stands apart as the island’s premier seabird viewing site. The density and variety of nesting species visible from a single overlook is exceptional by any standard, and the ocean backdrop gives the experience a scale that purely terrestrial wildlife sites rarely achieve.

The road to Polihale requires navigating several miles of unpaved track through former agricultural land before the dunes appear — a barrier that keeps crowds at bay and delivers those who persist to one of the longest beach stretches in Hawaii. Polihale State Park anchors the far western end of Kauai, where the Napali Coast cliffs meet the shore and the beach extends southward in a wide band of sand backed by dunes rising fifteen to twenty feet above the waterline.

The scale of Polihale is its defining quality. The beach runs for roughly five miles and sees a fraction of the foot traffic that Kauai’s more accessible southern shores attract. Swimming is generally not safe here due to strong currents and heavy shore break, particularly in winter, but the beach rewards those who come to walk, watch the sunset, or simply experience a Hawaiian coastline without development on the horizon. The Napali cliffs rise dramatically at the northern end, providing a backdrop that changes color through the afternoon.

The access road requires a high-clearance vehicle and is impassable when wet; checking conditions after rain before attempting the drive is essential. The park is open during daylight hours and has basic facilities. Summer months bring calmer surf and the most reliable road conditions. Arriving in the late afternoon allows time to explore before settling in for what are consistently among Kauai’s finest sunsets.

Kauai’s western coast receives far less visitor attention than the north shore or the resort areas of the south, and Polihale represents that quieter side at its most expansive. For travelers willing to accept the rough access road, it offers a Hawaiian beach experience defined by space, silence, and the dramatic convergence of cliff and ocean that marks the end of the Napali Coast.

The earthen walls of a star-shaped fort rise from the mouth of the Waimea River on Kauai’s southwest coast, an improbable relic of early nineteenth-century geopolitical maneuvering in the Pacific Ocean. Pa’ula’ula State Historical Park preserves a fortification built around 1817 under the direction of a Russian trading company agent who had negotiated an alliance with a Kauai chief, attempting to gain a commercial foothold in the Hawaiian Islands. The scheme failed — the Hawaiian king and the Russian government both rejected it — but the fort’s walls survived.

The park is largely undeveloped, giving it an archaeological character that more polished historical sites lack. Visitors walk among the low basalt walls and earthworks, reading interpretive signs explaining the fort’s brief construction and even briefer operational life. The site commands views over the Waimea River mouth and the coastline where the first Western contact with Kauai occurred in 1778, when Captain James Cook made his initial Hawaiian landfall nearby. That layering of events gives the location significance disproportionate to its modest physical remains.

The park is open during daylight hours and free to enter. The terrain is flat and the walk takes twenty to thirty minutes. Waimea town, just a short distance away, has restaurants and shops that pair naturally with a visit. The site is exposed to coastal wind and sun, so a hat and sunscreen are advisable. It functions well as a stop along the route to Waimea Canyon rather than a standalone destination.

Within Kauai’s historical landscape, Pa’ula’ula stands as a curiosity with genuine geopolitical weight — the physical trace of a moment when the islands’ independence hung in a different balance than most visitors imagine. Its quiet, unrestored quality makes the history feel more tangible than a fully reconstructed site might.
