Hugging the Koolau Mountain Range, this 3-mile, windward-side loop is a relatively short and easy hike leading to a 20ft waterfall with a deep swimming hole, where swimmers take turns scaling various-sized boulders to jump into the freshwater pool below. To reach the falls, you’ll have to ford Maunawili Stream a few times, and meander through tropical fruit groves, kukui nut, coffee, and monkeypod trees. This path, like many waterfall trails, is especially muddy, so prepare to dirty up your hiking shoes and car floor mats.
How to get there: From Waikiki, take the H-1 Highway west and merge onto the Pali Highway. Turn right onto Auloa Rd and park on the side of the road in the residential neighborhood.
