Lewis Falls
Lewis Falls is an approximately 30-foot waterfall on the Lewis River just south of Lewis Lake in southern Yellowstone National Park, easily seen from the road about 11 miles inside the South Entrance. Parking lots flank the Lewis River bridge on either side.
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 Yellowstone National Park (NPS) for closures and current conditions, and confirm land status before setting out.

Frequently Asked Questions
Lewis Falls drops about 30 feet. That makes it the 532nd-tallest documented waterfall in this inventory, taller than roughly 23% of the falls listed here. Height comes from published land-manager and survey records, not from our own measurement.
Access is documented as roadside. No trail distance is on record for Lewis Falls. The nearest town is Grant Village. Confirm access and land status with Yellowstone National Park (NPS) before setting out — some documented falls have no public route at all.
Summer (June-September). Waterfall flow swings enormously with snowmelt and recent rain, so a fall that roars in spring can be a trickle by late summer.
