Maroon Lake to Crater Lake

The Maroon Lake to Crater Lake trail is one of Colorado's most celebrated hikes, originating at the iconic Maroon Lake in the Maroon Bells-Snowmass Wilderness outside Aspen. Trailhead access is via Maroon Creek Road, which is closed to private vehicles between 8 a.m. and 5 p.m. daily from late June through early October; hikers must use the mandatory Aspen Highlands shuttle, which costs approximately $8 round-trip and departs from the Aspen Highlands ski area parking lot. Outside restricted hours, visitors with a valid national forest pass may drive to Maroon Lake directly. No backcountry permit is required for the day hike to Crater Lake. The route covers 6.4 km (4 miles) round-trip with approximately 200 m (660 ft) of elevation gain, climbing through Maroon-Snowmass Wilderness from 2,977 m (9,767 ft) at the trailhead to 3,177 m (10,427 ft) at Crater Lake. The well-maintained dirt path begins at the east shore of Maroon Lake, offering the famous double-reflection view of the Maroon Bells across still water in early morning light. The trail proceeds through a riparian zone of willows and wildflower meadows along Maroon Creek before ascending into spruce and fir forest. At roughly the 2.5 km mark, the forest opens onto the boulder-strewn shore of Crater Lake, a glacially formed basin directly beneath the steep northwest faces of North Maroon Peak (4,274 m) and Maroon Peak (4,317 m). Trail surface alternates between packed dirt, rocky sections, and boardwalk bridging across wet meadows. The open meadow stretches have minimal shade with full sun exposure common from mid-morning onward. No drinking water is available on trail; pack at least 1.5 liters. Wildflowers peak in mid-July while the surrounding aspen groves turn golden from mid-September through early October, drawing large seasonal crowds.
