Overview

Hike 1.2 miles (1.9 km) roundtrip along a wide gravel roadbed that follows a mountain stream to a cascade surrounded by moss-covered rocks and mixed hardwood forest in Great Smoky Mountains National Park .

After a half-mile walk along Twentymile Trail to the first junction, take Wolf Ridge Trail one hundred yards from the first bridge and look to your right for a foot trail that leads to the Twentymile Cascade.

If you're up for more, you can continue on Wolf Ridge Trail to the Twentymile Loop Trail for a longer 7.6-mile (12.2-km) loop through one of the more remote areas of the Smokies known for its picturesque streams and shady hardwood forest. This longer loop includes narrower sections of trail with some muddy and rocky areas. Twentymile Trail is wider with fewer ups and downs than Wolf Ridge.

About this trail's facts

The lines are the National Park Service's public trails layer, the trailheads and the waterfalls, views, peaks and historic places along them the Service's public points of interest, read 2026-10-16 and simplified for the map; the length is the line's, end to end. The write-ups are the Service's own "things to do" text, unedited. Heights come from USGS 3DEP through Terrain Tiles on AWS (Mapzen/Tilezen), read along each line and rounded; a short trail on steep ground can be off by a few tens of feet. Closures change: check the park's own site before you go.
