Big Island adventure activities and experiences

Adventure Seeker: Kāʻelo (The Thrill)

The rush of wind, the silent grace of giants, the endless stars from 14,000 feet

Written by a Local Expert

The Island is Your Adventure Park

The rush of wind in your face as you zip across a waterfall gorge. The silent grace of a manta ray gliding beneath you in the dark ocean. The thin air and endless stars from nearly 14,000 feet above sea level. The Big Island doesn't just offer adventure. It surrounds you with it.

A lot of folks ask me about the big adventure parks they've heard of, like Coral Crater. That's a great spot, but it's over on Oʻahu! Here on the Big Island, our adventure parks are the island itself. We don't need to build the thrill. We just strap in and ride through it.

From sea level to nearly 14,000 feet, from tropical rainforests to volcanic deserts - the Big Island is nature's ultimate playground where every adventure comes with a story and a connection to the island's incredible power.

High-Adrenaline Rush

Ziplines, ATVs & Waterfall Adventures

Kalani's Premier Pick: The Umauma Experience

This is my go-to recommendation for friends who want a bit of everything. Set along the dramatic Hamakua Coast, this adventure park offers the most comprehensive thrill package on the island.

The star attraction is their 9-line zipline course soaring over 14 waterfalls, including the stunning triple-tier Umauma Falls. But don't stop there. They also run guided ATV tours on a 5.5-mile trail, offer "Zip N Dip" packages combining ziplining with kayaking and swimming in a private section of the Umauma River, plus waterfall rappelling and horseback riding.

Kalani's Tip:

This is a full day of fun, so plan accordingly. The zipline over the falls is the money shot, but don't sleep on the ATV tour. You get muddy, and the views of the Hamakua coast are unreal.

Kalani's Cultural Pick: Aloha Adventure Farms

If you want your adventure to come with a story, this is the place. Their ATV tours take you on a journey through Polynesia, with stops at recreated "islands" representing Hawaiʻi, Fiji, Tonga, and Samoa. At each stop, guides share cultural knowledge and lead interactive activities.

The standout experience is their wood carving tour, where you learn from a 4th-generation Tongan master carver and create your own souvenir. It's less about pure speed and more about connecting with the spirit of Polynesia.

Kalani's Tip:

My kids love the carving tour. It's a meaningful souvenir they made themselves, and the cultural stories stick with them long after the adventure ends.

Into the Deep Blue

Ocean Adventures & Marine Life

Kalani's #1 Can't-Miss Experience: Manta Ray Night Snorkel

This isn't just an activity. It's a life-changing encounter. Picture this: you're floating in the dark ocean, powerful underwater lights illuminating the plankton-rich water below. Suddenly, massive manta rays appear, their wingspans reaching 12 feet across, gliding through the light in a silent, graceful ballet. They swim within inches of you, completely unbothered by your presence.

This experience consistently ranks as one of the most unforgettable activities in all of Hawaii. The rays come to feed on the plankton attracted by the lights, creating a magical underwater dance.

Kalani's Tip:

Don't just book the cheapest tour. Look for operators with smaller groups and a strong commitment to conservation, like Sea Paradise. And trust me, it's worth it to go with a boat. The shore snorkel is a different experience, but the boats take you to the main "Manta Village" off Keauhou Bay, which is the premier viewing spot.

World-Class Snorkeling Spots

Kealakekua Bay

Snorkeling here feels like swimming through a historical movie set. This protected Marine Life Conservation District offers water clarity up to 100 feet and vibrant coral reefs teeming with tropical fish.

The backdrop is the Captain Cook Monument, marking where the famous explorer first landed and later died. The challenge of getting here (requiring a strenuous hike or boat trip) helps preserve its pristine condition.

Hōnaunau Bay (Two Step)

This spot earns its nickname from the two natural lava rock "steps" that make ocean entry incredibly easy. Located right next to Puʻuhonua o Hōnaunau National Historical Park.

The calm, clear water teams with tropical fish, and Hawaiian green sea turtles are frequent visitors. It's ideal for snorkelers of all skill levels and families with children.

Kalani's Tip:

Visit Two Step early in the morning to beat crowds and see the most active marine life. For Kealakekua Bay, a guided boat tour is the best way to experience it. The captains share the rich history of the bay, and they take you directly to the best snorkeling spots without the grueling hike.

To the Heavens: Mauna Kea

Sacred Summit & Stargazing

Before we talk about the experience, we need to talk about respect. Mauna Kea isn't just a mountain with telescopes. It's a sacred place in Hawaiian cosmology, considered the realm of the gods. Approaching this summit requires cultural sensitivity and understanding of its deep spiritual significance.

The journey itself is an adventure in extremes. You start at sea level and rapidly ascend to nearly 14,000 feet, transitioning from tropical warmth to near-freezing temperatures. The highlight comes at sunset, when you're literally above the clouds, watching the sun disappear into an endless sea of white. Then, as darkness falls, the sky reveals itself in a way that seems almost artificial in its brilliance.

Critical Safety Information:

Vehicle Requirements:

• 4WD vehicle mandatory for final ascent
• Stop at VIS (9,200 ft) for 30 minutes
• Don't try with rental sedan

Health & Weather:

• Bring warm layers & gloves
• No ascent within 24hrs of diving
• Best viewing: April-October

Kalani's Tip:

Don't even think about trying to drive your rental sedan up here. It's dangerous, violates your rental agreement, and you'll likely get stuck. A guided tour is the safest, most comfortable, and most informative way to experience Mauna Kea. They handle the driving, provide heavy-duty parkas and hot drinks, and their guides share the stories of the mountain and the constellations.
