Horseshoe Falls is a 45-foot cascade on the Roaring River in Rocky Mountain National Park, Larimer County, Colorado, at about 8,682 feet. It sits at the head of the Alluvial Fan, the boulder field left by the 1982 Lawn Lake flood, and is seen from an accessible trail off the road to Endovalley.
The falls
The Roaring River comes down a long, steep descent here, where the notable cascade at the bottom drops about 45 feet. Below it the water spreads through the granite boulders of the fan. The 1982 flood likely reshaped the falls heavily.
Getting there
The Alluvial Fan is off the road to Endovalley, with a west parking area; the Park Service rebuilt the trail in 2020 and designed it to be fully accessible. It winds up to a 56-foot bridge across the Roaring River that leads to the east side of the fan, with views of Horseshoe Falls and the Mummy Range.
Admission to Rocky Mountain National Park is $30 per vehicle for one day or $35 for seven days, plus $100 per person for non-US residents aged 16 and older unless they hold an Annual or America the Beautiful Pass. From May 22 to October 12, 2026, a timed entry reservation is required to enter between 9 a.m. and 2 p.m.; the only cost is a $2 Recreation.gov processing fee.
When to go
Snowmelt drives the strongest flows in this part of the Southern Rockies. In autumn, aspen color shows in Endovalley.
On site
From April 15 to August 31, the park closes Horseshoe Park and the West Alluvial Fan to foot travel off roads and designated trails to protect bighorn sheep. During the elk rut, September 1 to October 31, Horseshoe Park is closed to foot travel and fishing from 5 p.m. to 10 a.m. Pets are allowed only within 100 feet of roads and parking areas. Restrooms are at the west parking area and the Lawn Lake Trailhead.
History and name
In 1982 the earthen dam at Lawn Lake failed and sent most of the lake down the Roaring River valley, sweeping away vegetation and dropping the debris that built the Alluvial Fan. Interpretive signs along the trail tell the story.
