The Ultimate Guide to Things to Do in Big Island Hawaii

The Big Island of Hawaiʻi is unlike any other place on Earth. It’s bigger than all the other Hawaiian Islands combined, and with that size comes jaw-dropping diversity. In a single trip, you can hike across fields of hardened lava, relax on a pristine white sand beach, snorkel with manta rays under the stars, sip world-famous Kona coffee, and explore rainforests filled with waterfalls.

If you’ve been dreaming about visiting Hawaiʻi, chances are you’ve seen photos of Maui’s lush valleys or Oʻahu’s bustling Waikīkī Beach. But the Big Island is something entirely different. It’s wilder, more rugged, and feels almost untouched in many places. It’s the island where adventure meets culture, and where nature constantly reminds you of its power.

In this guide, I’ll take you through the very best things to do on the Big Island of Hawaiʻi from volcanoes and beaches to food, culture, and travel tips. Whether you’re planning a quick getaway or a weeklong adventure, you’ll leave with plenty of ideas (and probably a strong urge to extend your trip).

Explore Volcanoes and Natural Wonders

1. Hawaiʻi Volcanoes National Park

No trip to the Big Island is complete without visiting Hawaiʻi Volcanoes National Park. It’s one of the few places on Earth where you can witness an active volcano shaping the land in real-time.

Here, you’ll find Kīlauea, one of the most active volcanoes in the world, and Mauna Loa, the largest volcano on Earth. Hiking across the vast landscapes feels otherworldly. You’ll pass through lava tubes, steam vents, and fields of hardened lava that stretch as far as the eye can see.

If you’re lucky, you might even catch lava glowing at night. It’s mesmerizing and humbling, a reminder of how alive our planet really is.

2. Mauna Kea Summit

From fire to ice, yes, you can actually experience snow in Hawaiʻi. Mauna Kea is the tallest mountain in the world when measured from its base on the ocean floor, and its summit offers some of the clearest skies for stargazing anywhere on Earth.

Watching the sunset above the clouds from Mauna Kea is a spiritual experience. Once the sky darkens, astronomers set up telescopes, and you can gaze at planets, constellations, and even galaxies millions of light-years away.

You can drive yourself, but many travelers prefer the ease of a Mauna Kea sunset and stargazing tour that includes transportation and expert guides.

3. Akaka Falls State Park & Rainbow Falls

If waterfalls are your thing, the Big Island won’t disappoint. Akaka Falls plunges 442 feet into a lush gorge, surrounded by tropical rainforest. The short, paved loop trail is easy and perfect for families.

Closer to Hilo, Rainbow Falls is named for the rainbow that often appears in its mist during sunny mornings. Both are easy stops, and many guided waterfall tours combine them with visits to local farms or cultural sites.

Beaches and Coastal Adventures

4. Famous Beaches

The Big Island has some of the most unique beaches in Hawaiʻi. Unlike Maui or Oʻahu, which are lined with endless sandy stretches, the Big Island’s beaches are more dramatic and varied.

• Hapuna Beach – Often ranked as one of the best beaches in the world, with powdery white sand and calm waters.
• Punaluʻu Black Sand Beach – Famous for its jet-black volcanic sand and sea turtles basking on shore.
• Papakōlea Green Sand Beach – One of only four green sand beaches in the world. The hike to get there is part of the adventure.

5. Snorkeling & Diving

• Kealakekua Bay – Known for its vibrant coral reefs and spinner dolphins. It’s also a historic site, marking where Captain Cook first landed in Hawaiʻi. The best way to see it is on a snorkel cruise that takes you directly to the best spots.
• Night Snorkel with Manta Rays – This is a must-do experience. This is a must-do. Book a manta ray night snorkel for an unforgettable evening. Huge manta rays glide gracefully beneath you, illuminated by underwater lights. It feels like floating in a dream.

6. Whale Watching & Dolphin Tours

From December to April, humpback whales migrate to Hawaiʻi’s warm waters. Booking a whale watching cruise during this season is unforgettable. You’ll often see them breaching, tail-slapping, and playing with their calves.

Dolphin tours are available year-round, with spinner dolphins often spotted in pods off the Kona coast. Try a dolphin encounter tour for a close look.

Petroglyph Fields

You can see them at places like Puako Petroglyph Archaeological Preserve or near the Volcanoes National Park.

Local Towns & Culture

Beyond the natural beauty, don’t miss exploring the island’s towns.

• Hilo – Laid-back, lush, and filled with local charm. The Hilo Farmers Market is fantastic for fresh fruit and handmade crafts.
• Kailua-Kona – Bustling with shops, restaurants, and oceanfront views. It’s the gateway to many tours and activities.
