Best underwater experience on the island for kids who aren't strong swimmers — air-conditioned, no getting wet, and you still see coral, fish, and sea life up close. 45-minute tour descending 100 feet to a 25-acre natural coral reef. Children must be 36 inches tall. Sells out regularly — book well ahead. Pairs perfectly with a swim at Kamakahonu Beach next door.

Floating through century-old sugar plantation irrigation tunnels in inflatable kayaks — a completely unique and magical experience through remote Kohala rainforest. IMPORTANT: verify they are currently operating before booking as some sources indicate temporary or permanent closure as of 2026.

The only way to see private North Kohala waterfalls — the Kona side's answer to a waterfall experience since the west side is too dry for accessible waterfalls on your own. Ride in a 6-wheel-drive Pinzgauer off-road through sugar plantation history, hike a lush rainforest trail past 7 waterfalls, swim under a cascading fall, and finish with a private picnic lunch overlooking the dramatic Pololu Valley sea cliffs. Bring a bathing suit, closed-toe shoes, light jacket, and sunscreen. Rain gear provided.

8 ziplines, 6 sky bridges, and a rappel in the North Kohala rainforest. About 90 minutes from Kona resorts — transportation from resorts available. The Zip and Dip upgrade adds a private waterfall swim and picnic lunch — worth it for a full day adventure. Minimum age 8, weight restrictions apply — check before booking. Arrive 30 minutes early.
