Mānāwaiopuna Falls (Jurassic Falls)
A 400-foot plunge deep in Kauai's Hanapēpē Valley, famous as the 'Jurassic Falls' from the 1993 film Jurassic Park; on private Robinson-family land and reachable only by permitted helicopter landing, not on foot.
Before you go
Waterfalls are hazardous by nature — wet rock, cold water, and unstable edges — and flow varies enormously with season and recent rain. Trail figures here describe the route as documented, not conditions today. Check Private (Robinson family estate, Hanapēpē Valley) for closures and current conditions, and confirm land status before setting out.
