Adams Falls is a 50-foot series of cascades on East Inlet in Rocky Mountain National Park, Grand County, Colorado, a 0.3-mile walk from the East Inlet Trailhead on the edge of Grand Lake. It is the first stop on the East Inlet Trail on the park's west side.
The falls
East Inlet drops in steps through a narrow rock gorge. Lidar measurements indicate a cumulative drop of about 50 feet; earlier records noted two drops, and local estimates give about 55 feet. Stairs lead to two overlooks above the water.
Getting there
The East Inlet Trailhead, at 8,400 feet, is less than a mile from downtown Grand Lake. The walk to the falls is 0.3 mile one way with 79 feet of gain, suitable for hikers of all abilities, including families with young kids, taking under 30 minutes. The lot fills, so arrive early; there are restrooms at the trailhead.
Admission to Rocky Mountain National Park is $30 per vehicle for one day or $35 for seven days ($15 or $20 on foot), plus $100 per person for non-US residents aged 16 and older unless they hold an eligible annual pass. From May 22 to October 12, 2026, a standard timed entry reservation is required between 9 a.m. and 2 p.m., covering East Inlet: print the confirmation and display it on the dashboard. The reservation carries a $2 processing fee.
When to go
The trail is open year-round; in winter, snowshoes, Nordic skis or microspikes may be needed. Spring runoff brings the strongest and most dangerous flow.
On site
In 2022 a 21-year-old woman died after a fall near the falls. The park warns that its streams are extremely cold, deeper and swifter than they look, and flanked by slippery rocks during spring runoff; stay on the overlooks and away from the water. Dogs are not permitted on park trails.
History and name
The falls are named for Jay E. Adams, one of Grand Lake's earliest settlers.
