The Big Island of Hawaii is unlike anywhere else on Earth. Towering volcanoes, black sand beaches, lush rainforests, and some of the clearest night skies you’ll ever see—it’s a destination that leaves you breathless at every turn. If you’re planning your adventure, you’re probably searching for the best things to do in Big Island Hawaii. That’s exactly what this guide delivers. From epic hikes to hidden gems, cultural treasures to unforgettable adventure, here’s how to make the most of your trip.
Getting Around the Big Island
The Big Island is big. It’s nearly twice the size of all the other Hawaiian Islands combined, which means you’ll need wheels to explore it fully. Renting a car is the best way to experience the island at your own pace.
- Driving time matters. The drive between Hilo and Kona takes about 2.5–3 hours, so plan your itinerary with location in mind.
- Gas stations can be scarce in remote areas—top up before venturing off into valleys or volcano parks.
- Road trips are a must. Circle-island drives and coastal routes let you soak in scenic landscapes you can’t get from the air.
If you’re not renting a car, taxis and tours exist, but they limit your freedom. To uncover the best things to do in Big Island Hawaii, driving is essential.
Hawai‘i Volcanoes National Park
No trip is complete without exploring Hawai‘i Volcanoes National Park, one of the island’s most iconic experiences. Here, you’ll witness the raw, volcanic power that built Hawaii.
- Kīlauea Iki Trail: A four-mile hike that takes you across a crater floor where lava once bubbled.
- Thurston Lava Tube: Walk through a massive underground tunnel carved by flowing lava.
- Crater Rim Drive: A scenic route with panoramic views of volcanic landscapes.
- Ranger Programs: Guided tours add cultural and geological insights that make the experience unforgettable.
If you’re lucky, you may even see lava flows lighting up the night sky—a once-in-a-lifetime sight.
Chasing Waterfalls
The Big Island is home to some of Hawaii’s most beautiful waterfalls. They’re lush, powerful, and often surprisingly easy to reach.
- ʻAkaka Falls: A 442-foot plunge accessible via a short rainforest loop trail.
- Rainbow Falls: Just outside Hilo, where morning mist often forms rainbows at the base.
- Umauma Falls: A series of stunning cascades, perfect for photos or even a zipline adventure overhead.
Pack a rain jacket—these areas often get showers, but that’s what keeps them so lush.
Beaches You’ll Never Forget
When people think of Hawaii, they picture beaches. The Big Island delivers, but with some unique twists. Exploring the beaches is easily one of the best things to do in Big Island Hawaii.
- Punaluʻu Black Sand Beach: Famous for its shimmering black volcanic sand and frequent turtle sightings.
- Hapuna Beach: A classic white sand beach perfect for swimming and sunbathing.
- Maniniʻowali (Kua Bay): A turquoise gem near Kona, ideal for a relaxing day in the sun.
- Papakōlea Green Sand Beach: One of only four green sand beaches in the world. It takes a long hike (or bumpy 4×4 ride), but it’s worth it.
Whether you want to snorkel, relax, or just marvel at nature, the Big Island has a beach for you.
Snorkeling and Diving Adventures
The waters around the Big Island are teeming with life. If you’re an ocean lover, put snorkeling and diving high on your list of things to do in Big Island Hawaii.
- Manta Ray Night Snorkel: One of the island’s most unique experiences. After sunset, powerful lights attract plankton, which draws in massive manta rays. Swimming with them is magical.
- Kealakekua Bay: A historic and protected marine reserve with crystal-clear waters and vibrant coral.
- Two Step Beach: Just south of Kona, this easy-access snorkeling spot is great for beginners and experts alike.
Diving operators are plentiful, offering everything from beginner tours to advanced deep dives.
Helicopter Tours Over Paradise
The Big Island’s landscapes are so diverse, you’ll want to see them from above. Helicopter tours provide bird’s-eye views of waterfalls, cliffs, lava flows, and remote valleys. Many tours fly over the Kohala Coast or the lava fields near Hawai‘i Volcanoes National Park. It’s not cheap, but it’s unforgettable.
Stargazing at Mauna Kea
Imagine standing nearly 14,000 feet above sea level, surrounded by stars brighter than you’ve ever seen. That’s Mauna Kea. Because of its altitude and clear skies, it’s one of the best stargazing spots in the world.
- Sunset Views: Arrive before dark to catch a breathtaking sunset above the clouds.
- Observatories: While most aren’t open to the public, their presence highlights the importance of this location in astronomy.
- Tours Available: If you’re not comfortable driving up on your own, tours include telescopes, guides, and warm jackets.
Bring layers—it’s cold up there!
Hiking Valleys and Trails
The Big Island’s valleys and trails are a hiker’s paradise. They combine raw natural beauty with cultural history.
- Waipiʻo Valley: Known as the Valley of the Kings, with steep cliffs, waterfalls, taro fields, and a black sand beach.
- Pololū Valley: A shorter hike than Waipiʻo, but equally stunning with sweeping coastal views.
- Mauna Loa Trails: If you’re up for a challenge, trek across the slopes of the world’s largest volcano.
Hiking here isn’t just about exercise—it’s about immersing yourself in the island’s soul.

Practical Tips for Visiting
A few essentials will help make your trip smoother:

- When to Visit: Winter brings whale watching; summer offers calmer seas. Anytime is good—but pack for both rain and sunshine.

With the right preparation, your adventure will be unforgettable.
