Hoʻopiʻi Falls is a pair of modest cascades (the main drop around 20 feet) along a forested trail near Kapaʻa on Kauai, with the round-trip hike roughly 1.8 miles and about 160 feet of elevation gain. The swimming holes and easy jungle walk make it a local favorite.
At 20 ft, it stands above roughly 12% of the 775 documented falls in this guide.
Its water comes from Kapaʻa Stream. You'll find it in Kauai, Hawaii. It is protected within Kauai County / private easement.
This is a short hike waterfall: reached by a short trail, generally under about a mile each way. A short walk gets you to the viewpoint, so it works for most casual visitors and families. The walk to the main viewpoint runs about 1.8 miles round trip. Base a visit out of Kapaʻa, the closest town.
When to go: year-round. Like most waterfalls, Hoʻopiʻi Falls runs highest after snowmelt or heavy rain and can thin out in late summer, so it's worth checking recent streamflow and the land manager's conditions page before a long drive.
