Cathedral Lake trailhead

About

The Cathedral Lake trailhead in Aspen, Colorado, serves as the starting point for a moderate day hike to an alpine lake at 11,866 feet. The trail begins near the intersection of Highway 82, Maroon Creek Road, and Castle Creek Road. Hikers ascend approximately 1,986 feet over a round-trip distance of 5.6 miles. The route climbs through Pine Creek canyon, passing aspen groves, spruce-fir forests, and meadows. The initial 0.75 miles through the aspen forest are gradual before the terrain steepens near the creek. The final approach to the lake involves a steep climb with switchbacks on a shelf below the water. Fall conditions from September through November typically feature dry trails and yellow aspen foliage, though early snowfall is possible at this elevation. Parking is available at the trailhead, but designated bathrooms are not present on-site; hikers can use outhouses at the nearby Ashcroft Ghost Town. The trail is pet-friendly and popular, often crowded during peak foliage. No permits are required for day hikes, though overnight camping requires registration.
