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.
