Big Island Hawaii: Things To Do

The Big Island’s activity range is wider than any other Hawaiian island — the island spans eleven of the world’s fourteen climate zones, and the range of experiences reflects that. You can drive from a white-sand resort beach to a 13,796-foot summit in two hours; from a coffee farm at 1,500 feet to an active volcanic crater in another two. The island’s sheer scale rewards multiple days. This guide covers the main activities with fees and logistics current as of 2026.

Hawaii Volcanoes National Park

323,431 acres of active volcanic landscape, approximately 45 minutes south of Hilo and 2.5 hours from Kailua-Kona. Entry $35/vehicle, valid for seven days. Open 24 hours — check nps.gov/havo for current eruption status before arrival.

Kīlauea Caldera and Halema’uma’u Crater — The primary attraction. The Kīlauea Overlook offers the best view of the caldera’s 2.5-mile width. When Halema’uma’u is actively erupting, the lava lake glows intensely at night, visible from the overlook. Nighttime is the most dramatic time to visit — plan to arrive at dusk and stay through full dark. During active eruptions, sunrise and sunset are also striking.

Crater Rim Drive — A partially restored loop road around the caldera rim (the 2018 eruption damaged sections that have been reopened progressively). The drive passes through sulfur banks, steam vents, and several trailheads.

Thurston Lava Tube (Nāhuku) — A 500-year-old lava tube accessible via a 20-minute loop trail through tree fern forest. Lit internally; no flashlight required. Free with park entry. One of the most accessible and underrated stops in the park.

Chain of Craters Road — 18 miles descending 3,700 feet to the coast. Key stops along the way include the Mauna Ulu lava shield (extensive lava flow fields from 1969–1974 eruptions, now cooled and walkable via marked trails), Pu’u Loa Petroglyphs (a 2.4-mile round-trip walk to Hawaii’s largest petroglyph field, with approximately 23,000 images), and the Hōlei Sea Arch at road’s end.

Volcano House — Even if not staying there, the rim-edge hotel lobby (open to day visitors) offers caldera views and a warm drink from the restaurant after a cold evening viewpoint visit.

Mauna Kea

At 13,796 feet above sea level — the highest point in Hawaii and, from ocean base to summit, the world’s tallest mountain. The summit hosts thirteen astronomical observatories from eight countries.

The Mauna Kea Visitor Information Station (MKVIS) at 9,200 feet is free and open daily 9am–10pm. Stargazing programs with telescopes run most clear evenings from the MKVIS (free; no reservation required for the public program). The atmosphere at 9,200 feet is noticeably thinner than at sea level — the standard recommendation is to spend 30 minutes here before attempting the summit.

Summit access: The unpaved summit road above the MKVIS requires a 4WD vehicle. Most standard rental cars are prohibited above the MKVIS by their rental agreements. Commercial stargazing tours from Kona and Hilo provide 4WD transport, summit access, professional guides, and warm clothing rental — approximately $200–250/person as of 2026. Tours typically depart in the afternoon, reach the summit for sunset, then descend to the MKVIS for the main stargazing session with high-powered telescopes.

Manta Ray Night Snorkeling

The Big Island has two of the most reliable manta ray aggregation sites in the Pacific: Keauhou Bay and Garden Eel Cove, both near Kailua-Kona. Manta rays — which reach wingspans up to 18 feet — feed on plankton attracted to the surface by dive boat lights. The experience involves snorkeling on the surface (or diving beneath) while mantas loop repeatedly just below and in front of you.

Tours run nightly from early evening, approximately 2 hours. Snorkel tours approximately $55–90/person; scuba tours approximately $100–140/person as of 2026. Operators include Jack’s Diving Locker, Manta Ray Bay Hotel & Dive Shop, and Sea Paradise Scuba. Sighting rates approach 90% over the course of the year — not a guarantee, but significantly more reliable than most wildlife experiences. Book at least a few days in advance during peak periods.

Black Sand Beaches

Punalu’u Black Sand Beach — South of Pahala off Highway 11, roughly halfway between Hilo and Hawaii Volcanoes. The most accessible black sand beach on the island. The sand is made of basaltic lava crystals — it absorbs heat quickly and can be uncomfortably hot in direct sun by midday. Hawaiian green sea turtles (honu) haul out here regularly and are among the most reliable in the state to observe. Swimming is hazardous (strong currents); the beach is for viewing and turtle watching. Free; parking and restrooms on-site. Federal law requires staying at least 10 feet from turtles.

Kehena Beach — Off Highway 137 in the Puna district. A black sand cove accessible via a steep lava trail (approximately 10 minutes). Informal clothing-optional beach. Spinner dolphins visit most mornings. Powerful shore break when swell is up — check conditions before descending. No facilities. Limited roadside parking.

Snorkeling

Two-Step / Hōnaunau Bay — Adjacent to Pu’uhonua o Hōnaunau National Historical Park, south of Kailua-Kona. A two-step lava shelf entry into bay water with excellent coral cover, high fish density, and regular spinner dolphin visits in the morning. Free; roadside parking. No facilities. One of the best shore snorkel sites on the Big Island.

Kahaluu Beach Park — 78-6740 Ali’i Dr, Kailua-Kona. An easily accessible reef snorkel site in Kailua-Kona with consistent green sea turtle presence. Lifeguard on duty. Free; parking approximately $5/day. Rental snorkel gear available from the beachside concession. Can be crowded midday.

Kealakekua Bay State Historical Park — South of Kailua-Kona. One of the most pristine snorkeling sites on the Big Island, with 100-foot visibility and large coral structures. The site is where Captain James Cook was killed in 1779; a white monument marks the spot on the bay’s north shore. Access to the best snorkeling is via kayak (rentals approximately $40–60 for a half day from operators in Captain Cook) or a snorkel boat tour from Kailua-Kona (approximately $80–120/person). Driving to the site and hiking down are technically possible but involve a steep trail and restrictions on swimming.

Waipio Valley

The northeastern tip of the Big Island, accessed from Honoka’a off Highway 24. Waipio (Valley of the Curving Waters) is a deeply cut valley dropping 2,000 feet from the Hamakua cliffs, with a black sand beach at its floor, taro farming, and a 2,000-foot waterfall (Hi’ilawe) at the valley’s back. The valley’s historical and cultural significance is profound — it was the residence of Hawaiian royalty and the site of a major battle that established Kamehameha I’s rise to power.

The lookout at the valley rim is free and open to all. Descending into the valley requires either a 4WD vehicle (rental car companies do not permit standard cars on the road — the grade exceeds 25% in places) or a guided valley tour by foot, horseback, or 4WD with local operators (approximately $60–120/person as of 2026). Swimming at the black sand beach requires checking for surf and rip current conditions — it is not reliably safe for casual swimming.

Pu’uhonua o Hōnaunau National Historical Park

Highway 160, south of Kailua-Kona. Under ancient Hawaiian law, someone who broke a kapu (sacred law) — including commoners who accidentally touched the shadow of an ali’i (chief) — faced execution. The only escape was to reach a pu’uhonua (place of refuge) and receive absolution from a priest. The park preserves the physical remains of this sanctuary: a reconstructed Great Wall, a heiau (temple platform), and carved wooden ki’i akua (god images). Entry approximately $20/vehicle as of 2026. Open daily 7am–sunset. Well-maintained and informative; allow 1.5–2 hours.

Kona Coffee Farm Tours

The 30-mile belt of Kona coffee farms along Highway 180 above Kailua-Kona offers self-guided and guided tours at several major farms. Most are free.

Greenwell Farms — 81-6581 Mamalahoa Hwy, Kealakekua. One of the largest Kona coffee operations; free walking tours daily showing the full growing and processing cycle from cherry to cup. Tasting room open daily 8:30am–5pm.

Mountain Thunder Coffee Plantation — 73-1944 Hao St, Kailua-Kona (at higher elevation). Self-guided tours with a clear presentation of the washing and drying process. Free. Open daily 9am–4pm.

Kona Coffee Living History Farm — Mamalahoa Hwy, Captain Cook. A preserved 1920s Japanese immigrant coffee farm managed by the National Park Service. Entry approximately $5/person. Open Tuesday–Saturday 10am–2pm. The most educational stop for understanding the history of the industry.

Practical Notes

• Park entry timing: Hawaii Volcanoes is most dramatic at night. Drive to the park in the afternoon, see the crater at dusk and after dark, then either head back to Hilo or stay at Volcano House.
• Mauna Kea weather: Conditions at the summit change rapidly. Fog, rain, and wind are common even on clear days in Kona. Commercial tours generally have better weather forecasting than independent visitors.
• Driving distances: The Big Island is genuinely large. Kona to the park is 2.5 hours each way — factor this into planning. A split itinerary (two nights on the Kohala coast, two nights in Hilo or Volcano) covers more ground than trying to day-trip everything from one base.
