Kipahulu District, Haleakala National Park
Bamboo forest and a 400-foot waterfall past Hana.
The Pipiwai Trail climbs through a creaking bamboo tunnel to Waimoku Falls, and the short Kuloa Point loop overlooks the Pools of ʻOheʻo. The pools are closed to swimming, so come for the walking and the views. Keep driving past Hana town to get here, then budget real time for the trip back.
