Adventure Tours Hawaii

Plotting the rest of your day on Hawaii Island? Here are the tours with real, bookable space for today, refreshed as availability changes. Snorkel with manta rays off the Kona coast, stand at the edge of Hawaiʻi Volcanoes National Park, stargaze on Mauna Kea, or chase waterfalls and visit a working coffee farm. The Big Island's sheer size means there's usually something open somewhere, and many operators release same-day seats right up to departure. Choose your group size and the experience you want below to see what's confirmed for today, then book in a few taps. If today is filling up, check tomorrow — a little lead time opens up far more of the island's best tours.
