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 National Park Service for closures and current conditions, and confirm land status before setting out.
