Best Oʻahu hikes & hiking tours

There is no single best hike on Oʻahu — Diamond Head is the most iconic, Manoa Falls the prettiest waterfall trail, and Koko Head's 1,048 steps the most challenging of the popular climbs. Well-marked trails like Diamond Head and Manoa Falls don't need a guide, but guided hikes earn their cost on hidden-waterfall and off-the-beaten-path routes with access rules or real exposure. Note that Diamond Head now requires an advance reservation through the state parks system.

Oʻahu has some of the most dramatic hiking in the Pacific — volcanic craters, jungle waterfalls, ridgeline trails with views of both coasts, and bamboo forests that feel prehistoric. The tours below range from easy boardwalk strolls to serious scrambles, all vetted for guide quality and trail conditions.
