Tips from the Community

October 18, 2023, Hoʻopiʻi Falls Trail

Hoʻopiʻi Falls Trail is a trail through the jungle and leads from Kapahi Road to the Hoʻopiʻi Falls. The trail, that partly follows Kapaʻa Stream, is really short and completely flat, so you don't need any experience.

Upper Hoʻopiʻi Falls are the first falls along Hoʻopiʻi Falls Trail. The water falls into a little pool, where you can go for a little swim and cool down. Please be aware, that the path to the main falls in the eastern direction is on private property and behave accordingly if you wish to continue.

Cross Bach twice on the way there, shoes that are allowed to get wet are recommended, and because of the mud on the way there are good soles

The second waterfall of the walk along the Kapa’a stream. This one has a nice rocky exposed area that offers fantastic views of the fall.
