Offering some of the most picturesque views in the Rocky Mountains, Crater Lake is a clear, natural body of water located in the Maroon Bells Snowmass Wilderness outside of Aspen, Colorado. Crater Lake can be reached via a heavily-trafficked out and back hiking trail, about two miles from the Maroon Lake parking lot in the White River National Forest.
With a surface elevation of 10,075 feet, hikers must climb approximately 500 feet along rocky terrain to reach the shores of Crater Lake. The lake fluctuates in size before ultimately drying up in October each year. The trail is extremely popular all year round, with gushing spring waterfalls, cool summer nights, and vibrant autumnal colors.
At the lakeshore, visitors are greeted with panoramic views of the Elk Mountains’ most iconic features including the Maroon Bells, Pyramid Peak, and the Sleeping Sexton.
Due to its common name, Crater Lake may be confused with Oregon’s Crater Lake National Park, Crater Lakes Trail near Boulder, or the Carter Lake Reservoir west of Loveland, Colorado.
Crater Lake Accessibility
Crater Lake is most easily accessible via the Maroon Lake Trail. In the winter, access to Crater Lake remains open for hiking, snowshoeing, and nordic skiing, although the road to the parking lot is seasonably closed to vehicles approximately 7 miles from the trailhead.
Due to the area’s popularity, parking is very limited at the Maroon Lake Trailhead. In the summer and fall, visitors can take a shuttle from the Aspen Highlands Ski Area to the parking lot. Shuttle information can be found on the RFTA website.
In 2021, reservations may be required to visit the Maroon Bells Wilderness area. Information can be found here: aspenchamber.org
Despite the trail’s total roundtrip length of 3.8 miles, the journey to Crater Lake is still considered moderately difficult. In peak season, the area is very crowded and dogs must be kept on leashes. There are bathrooms and picnic facilities located near the parking lot.
