★★★★★★★★★★4.5 · 45 reviews · 6 hours (approx.) · from $196Our pick

Downhill bike into Pu'u 'Ohia rainforest, then an optional waterfall hike with hotel pickup, helmets, rain gear, and expert guides in Honolulu.

“Loved our guide. He was very informative and helpful. My only complaint would be about the length of the bike tour itself. We all wished it had been longer and not necessarily all downhill.”
