Rocky Mouth Falls
Rocky Mouth Falls is a waterfall of roughly 70 feet tucked into the Wasatch foothills on the east side of Sandy, reached by a short 0.8-mile round-trip hike up wooden steps and a dirt-and-rock trail that gains about 285 feet. Dogs are not allowed because the area is within a protected watershed.
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 Sandy City / Uinta-Wasatch-Cache National Forest for closures and current conditions, and confirm land status before setting out.

Spring snowmelt (Apr-Jun). Waterfall flow swings enormously with snowmelt and recent rain, so a fall that roars in spring can be a trickle by late summer.
