Fun Things to Do with Teenagers on the Big Island of Hawaii

From lava fields to manta ray night dives, the Big Island has the kind of adventure that impresses even the most jaded teenager.

Fun Things to Do with Teenagers on the Big Island of Hawaii

If you have ever tried to plan a family vacation that genuinely excites a teenager, you know the struggle. They have outgrown the kiddie pool. They are over the resort buffet. They want something that feels real, something worth posting about, something that makes them forget their phone for at least five minutes. The Big Island of Hawaii is that place.

The Big Island is the largest island in the Hawaiian chain, and it has a landscape so varied it feels like visiting multiple destinations in one trip. Active volcanoes, black sand beaches, manta rays gliding through dark water, waterfalls hidden in rainforest, and some of the best stargazing on the planet. This is the island that delivers experiences teenagers actually remember.

Here is our family-tested list of the best things to do with teenagers on the Big Island.

Hawaii Volcanoes National Park

This is the centerpiece of any Big Island trip with teens. Hawaii Volcanoes National Park is home to Kilauea, one of the most active volcanoes in the world, and the massive Mauna Loa. Walking across hardened lava fields, peering into the Halema'uma'u crater, and exploring lava tubes gives teenagers the kind of wow factor that no theme park can match.

Start with the Kilauea Iki Trail, a 4-mile loop that descends into a crater and crosses the solidified lava lake. It is moderately challenging and completely surreal. Bring a lightweight hiking daypack for water and snacks, and wear sturdy shoes with good grip.

The Thurston Lava Tube is a quick, easy walk through a 500-year-old tube formed by flowing lava. It is dark, damp, and exactly the kind of thing teens love. If you visit at night, the glow of the crater against the sky is unforgettable.

Manta Ray Night Dive or Snorkel

This is the experience that tops every teen's list after the trip. Off the Kona coast, operators take small groups out at night to float on the surface while massive manta rays - some with wingspans over 12 feet - glide inches below you, feeding on plankton attracted by underwater lights.

Most operators allow kids 10 and up for snorkeling and 12 or older for diving. It is safe, well-supervised, and absolutely magical. Make sure everyone has a waterproof phone pouch because you will want photos even though the operators usually provide them. For teens who want to capture the full experience, an AKASO Brave 7 action camera is waterproof and shoots great video in low light conditions.

Black Sand Beaches

Punalu'u Black Sand Beach is the most famous, and for good reason. The jet-black sand is made from volcanic basite lava that shattered as it hit the ocean. Green sea turtles regularly haul out on the beach to rest, and you can watch them from a respectful distance.

Pack a quick-drying microfiber beach towel because the black sand heats up fast in the sun and you will want something to sit on. A pop-up beach tent with UPF 50+ protection is also a smart move since shade is limited at Punalu'u.

Snorkeling at Two Step (Honaunau Bay)

Located right next to the Place of Refuge (Pu'uhonua o Honaunau National Historical Park), Two Step is named for the natural lava rock steps you use to enter the water. The marine life here is incredible - spinner dolphins, sea turtles, tropical fish in every color, and visibility that stretches 100 feet or more.

This is a step up from beginner snorkeling, so it is perfect for teens who are comfortable in the ocean. The entry can be a little tricky with surf, but once you are in, the reef drops off beautifully. A full face snorkel mask makes it easier for teens who are still getting comfortable breathing through a traditional snorkel.

Stargazing on Mauna Kea

Mauna Kea's summit sits at nearly 14,000 feet and is home to some of the world's most powerful telescopes. While the summit itself requires careful acclimatization, the Visitor Information Station at 9,200 feet offers free stargazing programs several nights a week with telescopes set up by knowledgeable volunteers.

The sky up there is unlike anything your teenager has seen. The Milky Way is not a faint smudge but a blazing river across the sky. Bring warm layers because temperatures drop into the 30s and 40s even in summer. A portable charger keeps phones alive for star photography apps and long-exposure shots.

Zipline Adventures

The Big Island has several zipline courses that take advantage of the dramatic terrain. The longest lines run over tropical gulches, past waterfalls, and through rainforest canopy. Most courses require participants to be at least 10 years old and weigh between 70 and 260 pounds.

The Kohala Zipline on the north end of the island runs nine lines through a canopy above old sugar plantation land. The Umauma Experience near Hilo includes a zipline plus waterfall rappelling for teens 12 and older. Both are worth the drive.

Hiking to Akaka Falls and Waipio Valley

Akaka Falls State Park is a short, paved loop that leads to a stunning 442-foot waterfall. It is easy enough for anyone but dramatic enough to impress. Waipio Valley, on the other hand, is a serious adventure. The road down is the steepest road in Hawaii (a 25% grade), and the valley floor features black sand beach, taro fields, and wild horses.

You can hike down (and back up, which is the hard part) or take a shuttle. Either way, bring KEEN water sandals because the valley floor can be muddy and you will likely cross streams. A waterproof dry bag backpack keeps electronics and snacks safe from rain and river crossings.

South Point and Green Sand Beach

Ka Lae, the southernmost point in the United States, is a windswept cliff where locals jump into the ocean from a 40-foot platform. Teenagers will be drawn to it like magnets. Whether or not you let them jump is a personal call - the water is deep and the ladders are there for climbing back up, but it is not supervised.

From South Point, you can hike 2.5 miles to Papakolea Green Sand Beach, one of only four green sand beaches in the world. The olivine crystals in the cinder cone give the sand its distinctive color. The hike is hot and exposed, so bring plenty of water in a CamelBak water bottle and wear reef-safe sunscreen.

Coffee Farm Tours in Kona

Teenagers who are starting to appreciate (or depend on) coffee will love touring a working Kona coffee farm. Several farms in the Kona Coffee Belt offer free or low-cost tours where you can see the trees, learn about processing, and taste freshly roasted coffee.

Greenwell Farms and Hula Daddy Kona Coffee are two excellent options. Even non-coffee-drinking teens enjoy the tasting experience and the beautiful hillside settings overlooking the coast.

Packing Essentials for Big Island Adventures with Teens

The Big Island's diverse climate zones mean you need to pack for everything from tropical beach days to chilly mountain evenings. Here is what we never travel without:

The Big Island is the Hawaii trip that transforms a reluctant teenager into an enthusiastic travel companion. The scale of the landscape, the variety of adventures, and the sheer novelty of walking on a volcano or floating with manta rays - it creates the kind of family memories that survive the teenage years and become the stories they tell as adults.
