Hanakāpī‘ai Falls is without a doubt the best day hike on Kaua‘i. It offers both challenges and rewards to satisfy any explorer's dream of an authentic Hawaiian adventure. This hike averages 4-miles round trip if starting at Hanakāpī‘ai Beach and 8-miles round trip from Kē‘ē Beach. This adventure is just the first leg of the world famous Kalalau Trail, which twists and turns along the mountainous Nāpali Coast. After coming to the Hanakāpī‘ai Valley the path becomes a strenuous journey inland, fit for serious hikers. Beginning three-quarters of a mile in, the trail passes through flowing streams. All efforts are rewarded as the sight of the Hanakāpī‘ai waterfall graces the path before you as water crashes to a pool below, falling an amazing 300-ft from pure, green cliffs. Hikers should be warned to never attempt the trail in the rain as the streams are prone to flash floods. Check weather conditions before attempting and keep safety first!
