Olomana "Three Peaks" Trail is the best hike on O'ahu

Three Peaks is simply my favorite hike to do in Hawaii. It has breathtaking views, rock climbing, and a challenging incline. The hike is over four miles and can be considered a challenging. The third peak should only be attempted by experienced climbers. It is on the windward side of the Island, near Kailua. If you are looking for an adventure, try Three Peaks.
