The Best Things to Do on the Big Island
The Big Island covers 4,028 square miles — more than all the other Hawaiian islands combined. That footprint creates something no other island can match: tropical rainforest on the Hilo side, arid lava desert along the Kohala Coast, snow on the peaks above 13,000 feet, and active lava flows rewriting the shoreline in real time.
That range directly shapes what you can do here. Watch an active volcano reshape the landscape at Hawaiʻi Volcanoes National Park. Swim alongside giant manta rays off the Kona Coast after dark. Stargaze near 14,000 feet on Mauna Kea, where the air is so thin and dry that thirteen international observatories set up on the summit. No other Hawaiian island offers that spectrum in a single trip.
Below you'll find our picks — the activities that consistently deliver, the operators we trust, and the pricing you need to plan your trip. For a focused guide to lava viewing options, see our Top Volcano Tours on the Big Island.

Big Island of Hawaii Experiences
Hawaii’s Big Island is not only big in size, but also in diversity. Explore snowy mountaintops, lush jungles, windswept grasslands, picturesque beaches, and even lava fields- without ever leaving the island. And because we don’t want you to miss a thing, we’re spotlighting the very best Big Island Tours and Activities here.
If you’ve chosen Big Island, you’ve chosen to visit the epitome of paradise. Soar over cliffs and valleys, discover waterfalls, and sample some of the most delicious bounty Mother Nature has to offer. Plus, you can even walk on land that is younger than you are- isn’t that amazing! Tropical splendor, rich history, and big adventure combine perfectly to give you the best Hawaiian vacation imaginable. See what makes Big Island so special:
Water Activities
The Big Island's 266 miles of coastline deliver every kind of ocean experience. The Kona side stays calm and clear most of the year, with visibility regularly hitting 100 feet. That makes it the island's snorkeling and diving epicenter. Kealakekua Bay, a marine sanctuary accessible by boat or a steep trail, is routinely rated among the top snorkel spots in all of Hawaiʻi.
On the Kohala Coast, outfitters run everything from stand-up paddleboard tours to sunset catamaran sails. The Hilo side is rougher and rainier, but that's where the waterfall kayak tours operate — paddling into hidden bays and under cascading falls that the Kona side simply doesn't have.
Pricing runs $60–$180 for most half-day snorkel and boat tours. Kayak rentals start around $25/hour; guided kayak tours run $80–$150.
Volcanoes
Hawaiʻi Volcanoes National Park is the island's must-do. Two active volcanoes — Kīlauea and Mauna Loa — sit inside the park boundaries, and Kīlauea has been one of the world's most active volcanoes for decades. What you see depends on when you visit: during eruption phases, the Halemaʻumaʻu crater glows with a lava lake visible from multiple overlooks. Between eruptions, you can hike across fresh lava fields, explore the Thurston Lava Tube, walk past sulfur banks and steam vents, and study centuries-old petroglyphs along the coast.
Self-guided visits cost $30 per vehicle (valid for 7 days). Guided volcano tours range from $100–$200 per person and typically add expert narration, transport from Kona-side resorts, and stops at lesser-known sites that most visitors miss.
Hiking
Hawaiʻi Volcanoes National Park alone has over 150 miles of trails crossing lava flows, steam vents, and native rainforest. Outside the park, the Waipiʻo Valley road descends roughly 800 feet into a sacred valley of taro fields and black sand beaches. The Pololū Valley Lookout on the north tip offers a steep but rewarding descent to a remote shore.
For something less strenuous, the Kona coast delivers flat, scenic walks along historic sites — Kaloko-Honokōhau National Historical Park connects ancient fishponds, petroglyph fields, and a sea turtle resting beach in a short coastal walk. Birders should also compare Big Island birdwatching tours if Hakalau Forest, Kipukapuaulu Bird Park, or wetland birds are part of the plan.
Guided hiking tours run $80–$200, but many of the best hikes are free with just a park entrance fee or no fee at all.

Helicopter Tours
A helicopter tour is the only way to see the Big Island's full volcanic story in a single experience. From the air, you'll fly over Kīlauea's caldera (and the active lava lake during eruption periods), trace the Hamakua Coast's 2,000-foot sea cliffs, peer into the roadless Waipiʻo and Waimanu valleys, and count waterfalls that don't appear on any map.
Most operators fly out of Hilo or Kona. Hilo departures get you over the volcano faster; Kona flights add the Kohala Coast and more of the Hamakua waterfalls. Flight times range from 45 minutes to 2 hours. Doors-off flights are available from select operators for photographers.
Expect to pay $250–$500 per person depending on flight duration and helicopter type. Eruption periods sell out weeks in advance.

Coffee Farms
The Kona Coffee Belt, a narrow growing district on the western slopes of Hualālai and Mauna Loa, produces Hawaii's best-known coffee. Volcanic soil, upland cloud cover, and long-running family farms make this one of the Big Island's easiest food-and-agriculture stops to understand.
Farms along Mamalahoa Highway and the upland Kona roads offer tastings, public farm walks, and reserved tour experiences that change by operator and season. Use our Big Island coffee farm tours guide to pick a self-drive tasting loop, a reserved farm visit, or a guided food-and-coffee tour.
Macadamia Nut Farms
Hawaiʻi has been growing macadamia nuts commercially since the 1930s, and the Big Island remains the state's production center. The Hamakua Coast's rich volcanic soil and wet climate make it ideal growing territory.
The Mauna Loa Macadamia Nut Visitor Center south of Hilo is the most popular stop — a free self-guided tour through the processing facility with a factory store at the end. Smaller family farms offer more personal tours where you can see the trees, crack a fresh nut off the ground, and sample flavored varieties you won't find in stores.
Horseback Riding
The Big Island's paniolo (cowboy) heritage runs deep — Parker Ranch in Waimea is one of the largest cattle ranches in the United States, and Hawaiian cowboys were roping cattle here decades before the American West got started.
Several outfitters offer rides through landscapes you can't access any other way: rolling green pastures with Mauna Kea as a backdrop, cliffside trails above Waipiʻo Valley, and coastal rides along Kohala's northern shoreline. Most tours accommodate beginners and run 1.5–2.5 hours. Expect to pay around $100–$200 per person.
Stargazing
Mauna Kea's summit sits near 14,000 feet, above the cloud layer that usually caps at 6,000–8,000 feet. That's why thirteen international observatories chose this spot, and it's why a stargazing tour here is genuinely world-class.
Guided tours typically meet in Kailua-Kona or at the Visitor Information Station at 9,200 feet, provide cold-weather gear (summit temperatures regularly drop below freezing), and include telescope viewing time with expert guides who know the Hawaiian star stories alongside the science. Most tours time the ascent for sunset — which, from above the clouds, is its own spectacle.
Tours run $200–$300 per person. Independent summit access requires a 4WD vehicle (rental car companies prohibit their vehicles above the VIS). Full Mauna Kea summit and stargazing guide →

Manta Ray Night Dives
The Kona Coast is one of a handful of places in the world where manta rays reliably show up for a close encounter every single night. The mantas — with wingspans up to 12 feet — aren't trained or fed. They're drawn by lights that attract the plankton they filter-feed on. You float at the surface with a snorkel (or dive below with scuba gear) and watch them barrel-roll inches from your face.
This is the Big Island's most unique activity — no other Hawaiian island offers it. Two main sites operate nightly: "Manta Village" near Keauhou Bay and "Manta Heaven" off the airport coast north of Kailua-Kona. Sighting success rates exceed 90% year-round.
Snorkel trips commonly run $125–$160 per person; scuba dives are usually higher. Most operators provide all gear and run 1.5–2 hour trips departing at dusk.
Whale Watching
Humpback whales migrate from Alaska to Hawaiʻi's warm waters every winter, and Big Island whale watching runs roughly November through May, with peak activity January through March. The Kohala Coast and waters off Kailua-Kona are prime territory — you can often spot breaches from shore, but a boat puts you in the middle of the action.
Most whale watch boats depart from Honokōhau Harbor or Kawaihae Harbor. Trips typically run 2–3 hours and include hydrophone listening so you can hear the males sing underwater. The NOAA-regulated 100-yard approach rule keeps boats at a respectful distance, but humpbacks frequently breach and spy-hop much closer on their own.
Half-day trips run $40–$120 per person. Morning departures tend to have calmer seas.
Ziplining
The Big Island's zipline courses use the island's dramatic topography — deep gorges, tropical canopy, and waterfall views — rather than just height for thrills. The Umauma Falls zipline on the Hamakua Coast runs over a series of three waterfalls, which is hard to beat for scenery. Kohala Zipline near Hāwī threads through a native forest canopy in the island's remote north.
Most courses include 7–9 lines and take 2–3 hours. Weight and age minimums apply (check with each operator). Expect to pay roughly $225–$275 per person.
Waterfall Adventures
The windward (Hilo/Hamakua) side of the Big Island gets 130+ inches of rain annually, which feeds hundreds of waterfalls — many of them unreachable by road. That's the appeal: guided waterfall tours access cascades that most visitors never see.
ʻAkaka Falls (442 feet) and Rainbow Falls in Hilo are the easy wins — short walks, no guide needed. For the adventurous, Waipiʻo Valley hides Hiʻilawe Falls (1,450 feet, one of Hawaiʻi's tallest), and guided kayak-and-hike tours on the Hamakua Coast reach falls where the only trail is the river itself.
Deep Sea Fishing
Kona has been the big-game fishing capital of the Pacific since the 1950s. The 6,000-foot depth drop-off less than a mile from shore (one of the steepest in the world) puts blue marlin, yellowfin tuna, mahi-mahi, and wahoo within striking distance of even a half-day charter.
The annual Hawaiian International Billfish Tournament (running since 1959) cemented Kona's reputation. Most charters depart from Honokōhau Harbor. Half-day shared charters run $150–$300 per person; private full-day boats range $800–$2,000+.
Frequently Asked Questions
What are the best things to do on the Big Island?
The top things to do include Hawaiʻi Volcanoes National Park, the manta ray night snorkel, Mauna Kea stargazing, snorkeling at Kealakekua Bay, Punaluʻu Black Sand Beach, and exploring Waipiʻo Valley.
How many days do you need on the Big Island?
Most visitors need 5 to 7 days. The Big Island is twice the size of all other Hawaiian islands combined, so driving distances are real. Three to four days covers the Kona coast and Volcanoes National Park, but a full week lets you explore both coasts, the Kohala Coast, and the Hāmākua corridor. See our itineraries for day-by-day plans.
Is Kona or Hilo better?
Most visitors prefer Kona for sunny weather, resort beaches, and better snorkeling. Hilo is rainier but has waterfalls, the farmers market, and is closer to Volcanoes National Park. Ideally, spend time on both sides.
What should you not miss on the Big Island?
Do not miss Volcanoes National Park, the manta ray night snorkel, Mauna Kea stargazing, Kealakekua Bay snorkeling, and Punaluʻu Black Sand Beach. Waipiʻo Valley and ʻAkaka Falls are worth the drive.
Do you need a 4WD on the Big Island?
A standard rental car handles 95% of Big Island roads, including Volcanoes National Park, the Kohala Coast resorts, Hilo, and all major highways. You need a 4WD only for three specific roads: the Mauna Kea summit road above the Visitor Information Station at 9,200 feet, the unpaved route to Green Sand Beach at South Point, and the steep descent into Waipiʻo Valley. Most rental companies prohibit driving on these roads — guided tours are the safest legal option for Mauna Kea and Waipiʻo.
