12 Unique Things to Do on the Big Island of Hawaii (Beyond the Basics!)

The Big Island blew my expectations right out of the water. Nothing prepares you for standing at the edge of Kilauea’s massive crater at night, watching that orange lava lake glow against the dark sky. Or the moment you realize those “little black rocks” on the beach at Punaluu are actually sea turtles basking in the sun. This island is just wild.

Trust me, the things to do on the Big Island go way beyond just beach hopping (though the beaches here are insane). From swimming with manta rays at night near Kona to driving up Mauna Kea to watch the sunset above the clouds at 14,000 feet, this place feels like multiple worlds packed into one island. I’ve pulled together my favorite experiences that prove why the Big Island deserves way more than just a quick stop on your Hawaii trip.

Top Sights to See on the Big Island

Looking for the coolest things to do on the Big Island of Hawaii? Explore the stunning Volcanoes National Park, experience the thrill of a Manta Ray Night Dive, enjoy the breathtaking views at Waipio Valley Lookout, and visit the beautiful Akaka Falls State Park. Whether you’re interested in volcanic landscapes, marine adventures, or natural beauty, here are the top attractions to visit on the Big Island of Hawaii.

1. Hawai’i Volcanoes National Park

You don’t fully understand the Big Island until you stand on the rim of Kīlauea and watch it breathe fire. Hawai’i Volcanoes National Park is where Earth reminds you it’s still very much alive. Start with the Crater Rim Drive, which loops around active volcanic zones and scenic steam vents. Then make your way to Halemaʻumaʻu Crater—if it’s glowing at night, it’s surreal.

The Chain of Craters Road takes you all the way down to the coast, past lava fields that feel like another planet. When I visited, I timed it for sunset and caught the sky lit up in purples and oranges behind a smoking crater—it was unforgettable. Wear good shoes, bring water, and check conditions before hiking. If you’re into raw nature and dramatic landscapes, this is where you want to be. It’s intense, beautiful, and 100% worth it.

2. Manta Ray Night Dive

Swimming in the ocean at night sounds a little wild, but trust me—Manta Ray Night Dive near Kailua-Kona is unforgettable. You float on the surface with lights pointing down, and these massive manta rays—some over 12 feet wide—come gliding right past you. They’re attracted to the plankton gathering under your light, and they move so gracefully it’s like watching underwater ballet.

I did the snorkel version and had one brush so close I could feel the ripple. The guides from Manta Ray Dives of Hawaii were super chill and made everyone feel comfortable, even if it was your first night swim. Don’t worry, they don’t sting or bite. Just stay still and enjoy the show. This is hands down one of the most surreal experiences on the Big Island—and something you’ll tell everyone about when you get home.

3. Waipio Valley Lookout

It’s hard to beat the view from Waipio Valley Lookout. You’re standing high above this massive, lush valley with waterfalls streaming down the cliffs and waves crashing in the distance. Known as the “Valley of the Kings,” it’s one of Hawaii’s most sacred spots—and one of the most photogenic.

You can hike into the valley (the road is super steep, so prepare accordingly) or just soak in the view from the top. I didn’t go all the way down on my first visit, but even from the lookout, it felt like a scene from a movie. You’ll spot taro fields, wild horses, and if you’re lucky, mist curling up from the valley floor. Bring your camera and some snacks, and take your time with this one. Waipio Valley is where the island’s beauty really hits you.

4. Akaka Falls State Park

Akaka Falls State Park is an easy win if you’re looking for a quick nature fix near Hilo. The main trail is a loop—short and paved—but packed with tropical goodness. Ferns, bamboo groves, and orchids surround you as you walk toward the main event: Akaka Falls, a dramatic 442-foot drop straight into a green ravine.

I got there just after it rained, and the falls were roaring. It’s a powerful sight, especially when the mist rises and you catch a rainbow. You’ll also pass Kahuna Falls on the way, which is smaller but still worth a look.

It’s not a strenuous hike, so it’s great if you want something scenic without the sweat. I’d recommend hitting it early to avoid the crowds—plus, the morning light makes the whole place glow. It’s peaceful, refreshing, and totally worth the stop.

5. Mauna Kea Summit

Watching the sunset from Mauna Kea Summit is unlike anything else I’ve experienced. At 13,796 feet, it feels like you’ve left Earth. The air is thin, the clouds are below you, and the sun sets into a sea of orange and pink. Afterward, the sky transforms into a planetarium—clear, dark, and filled with more stars than you knew existed.

I booked a guided trip with Mauna Kea Summit Adventures to avoid the 4WD drive and altitude issues, and I’m glad I did. They brought jackets, hot drinks, and even telescopes.

I spotted Saturn’s rings with my own eyes. If you’re into stargazing or just want to see what the edge of the world feels like, this is it. Just layer up—it’s freezing up there even in summer. And remember, the summit closes during bad weather, so check ahead.

6. Hapuna Beach

If your Big Island bucket list includes a proper beach day, you can’t skip Hapuna Beach State Recreation Area. This place nails the classic white-sand beach vibe—half a mile of soft sand, gentle waves, and clear turquoise water that makes you want to stay all day. It’s one of the largest beaches on the island, and even when it’s busy, it doesn’t feel cramped.

I showed up with just a towel and some snacks and still ended up staying longer than planned. There are showers, picnic tables, and lifeguards, so it’s easy to make a day of it. The waves are usually mellow in summer, perfect for floating or swimming, though in winter they’re bigger and better for bodyboarding. If you’re chasing that picture-perfect Hawaii beach moment, Hapuna delivers without the crowds you’d expect.

7. Punalu’u Black Sand Beach

Punalu’u Black Sand Beach is one of those places you have to see to believe. The sand is jet black—thanks to cooled lava—and the contrast against the blue ocean is unreal. I wasn’t expecting to see sea turtles, but sure enough, there were two lounging right on the beach. Just chilling like locals.

The water here can be a little rough depending on the day, but there’s a calm area near the boat ramp that’s easier to wade in. You’ll find restrooms, shaded picnic tables, and palm trees swaying overhead.

I brought lunch and stayed for hours—it’s peaceful and has an untouched feel. If you’re looking for something that feels raw and naturally beautiful, Punaluʻu hits the mark. Don’t forget your reef-safe sunscreen—this spot gets hot fast under the sun.

8. Holualoa Village

Holualoa Village is a small hillside town above Kailua-Kona, and it’s where art and coffee collide. Tucked into the lush slopes of the Kona Coffee Belt, this village is lined with local galleries, studios, and coffee farms that welcome visitors without any big crowds or touristy fuss.

I wandered into Glyph Art Gallery on a whim and ended up talking with the artist for half an hour. Around the corner, I sampled small-batch coffee at a farm-to-cup café with ocean views.

What I loved most is how laid-back everything felt—no pressure to buy, just genuine people sharing their craft. If you’re into pottery, paintings, or unique souvenirs that actually support local creators, this is your spot. Holualoa isn’t flashy, but it’s full of personality—and a perfect break from the beach scene.

9. Kona Coffee Living History Farm

The Kona Coffee Living History Farm isn’t your typical museum—it’s a working coffee farm with hands-on experiences and real storytelling. Run by the Kona Historical Society, this spot brings the early 1900s to life, showing what life was like for Japanese immigrants farming coffee on the Big Island.

I visited on a weekday and ended up chatting with one of the staff members dressed in period clothing. She showed me how they used to roast beans by hand and even pointed out heirloom plants growing along the trail.

You can walk through the original farmhouse, check out the orchard, and, of course, sip freshly brewed 100% Kona coffee. I’ve done a lot of coffee tours, but this one felt personal, not polished. If you want to understand the culture behind those pricey beans in your kitchen, this is absolutely worth a stop.

10. Pu’uhonua o Honaunau National Historical Park

There’s something powerful about walking through Puʻuhonua o Hōnaunau, once a place of refuge for ancient Hawaiians who broke sacred laws. This historic site is quiet, beautiful, and filled with stories. Located on the Kona Coast, it’s where people could avoid death by reaching sanctuary before capture.

I went on a warm afternoon, and the mix of palm trees, lava rock walls, and carved wooden kiʻi (statues) made it feel like stepping into a different time. The Royal Grounds are also here, along with reconstructed hale (grass huts) and a protected shoreline full of tide pools.

Rangers occasionally offer cultural demonstrations like traditional games and canoe carving. It’s not flashy, but that’s the point—it’s a place to reflect. If you’re into history and want to experience Hawaiian heritage in a way that sticks, this is one of the island’s most meaningful stops.

11. Kealakekua Bay

Snorkeling at Kealakekua Bay is one of those rare travel moments you end up talking about for years. The water here is glassy and clear, with coral reefs and tropical fish just a few feet below the surface. I took a kayak out from Napoopoo Wharf and paddled across the bay—it’s a solid workout, but the payoff is unreal.

Once I reached the monument honoring Captain James Cook, I jumped in and was instantly surrounded by parrotfish, yellow tangs, and even a curious eel. It’s one of the best snorkeling spots in all of Hawaii, and way less crowded than spots near Kona. The cliffs around the bay keep it calm and protected, perfect for both beginners and experienced snorkelers. Just go early before winds pick up. Whether you arrive by kayak or tour boat, this place lives up to the hype.

12. Lava Tube Exploration

Wandering through a lava tube on the Big Island is as close as you’ll get to exploring another planet without leaving Earth. Formed by ancient lava flows, these tunnels snake underground and offer a surreal look at the island’s volcanic history. I joined a small group tour of Kazumura Cave, the world’s longest known lava tube, and didn’t expect it to be this cool—literally and figuratively.

The guide explained how lava hardened on the outside while molten rock continued flowing inside, creating these massive tunnels. We saw ropey lava patterns, skylights, and even a spot where the ceiling collapsed, letting in some light. Wear decent shoes and prepare to crouch now and then, but it’s doable for most people. If you’re tired of beaches and want something different, a lava tube tour is weird, wild, and surprisingly fun.
