Pe'e Pe'e Falls (pronounced Peh-eh Peh-eh Falls) is fed by the Wailuku River which also feeds Rainbow Falls further down river. Getting an up close view of Pe'e Pe'e requires a short hike down a hill and some rock skipping. The flow is determined by rainfall. The multi-spouted falls fills up a small pool at the base. Beware of mosquitoes. Take the right fork after Mile Marker 1 on Waianuenue Avenue in downtown Hilo and follow the signs to Rainbow Falls. Continue past Rainbow Falls for approximately one mile to Peepee Falls.There are restrooms at the park which opens at 7 a.m. and closes at 6:30 p.m.
