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 Humboldt-Toiyabe National Forest (USFS) for closures and current conditions, and confirm land status before setting out.
