Four Pass Loop

Nestled in the heart of the Elk Mountains, the Four Pass Loop is an iconic trek that takes you through some of the most breathtaking landscapes in the Maroon Bells-Snowmass Wilderness near Aspen, Colorado. This challenging loop covers approximately 42 kilometers (26 miles) and features a cumulative elevation gain of around 2300 meters (7,500 feet), offering seasoned hikers an exhilarating experience.Getting to the TrailheadThe journey begins at the Maroon Lake Trailhead, which is accessible by car or public transportation. If you're driving, take Maroon Creek Road from Aspen to the parking area near Maroon Lake. During the summer and fall, access by car is restricted, and you'll need to take a shuttle bus from Aspen Highlands. This helps to reduce traffic and protect the natural environment.Navigating the LoopThe Four Pass Loop can be tackled in either direction, but many choose to hike it counterclockwise to spread out the elevation gain. HiiKER is an excellent tool for navigation, providing detailed maps and waypoints to keep you on track.Maroon Lake to Crater LakeFrom the trailhead, you'll be greeted with the iconic view of the Maroon Bells, two of the most photographed peaks in North America. The first leg of the journey takes you to Crater Lake, a distance of about 2.7 kilometers (1.7 miles), with a modest elevation gain. The trail is well-traveled and offers stunning reflections of the peaks in the lake's waters.Ascending West Maroon PassLeaving Crater Lake, the trail becomes steeper as you approach West Maroon Pass, the first of the four passes. The ascent covers roughly 6.4 kilometers (4 miles) and takes you through wildflower-filled meadows and aspen groves before reaching the pass at an elevation of 3,658 meters (12,000 feet).Frigid Air Pass and BeyondAfter descending into the valley, you'll make your way towards Frigid Air Pass. This section of the trail offers a chance to spot wildlife, including elk and marmots. The pass itself sits at an elevation of 3,658 meters (12,000 feet) and provides panoramic views of the surrounding peaks.Trail Rider PassThe next segment leads to Trail Rider Pass, crossing through a landscape dotted with alpine lakes and streams. This pass is also at an elevation of around 3,658 meters (12,000 feet) and marks the halfway point of the loop. The descent from Trail Rider Pass brings you to the serene Snowmass Lake, a perfect spot for a rest or an overnight camp.Buckskin PassThe final pass, Buckskin Pass, is reached after a steady climb from Snowmass Lake. At an elevation of 3,962 meters (13,000 feet), Buckskin Pass offers some of the most dramatic vistas on the loop, with views of Pyramid Peak and the Bells.Completing the LoopThe descent from Buckskin Pass takes you through Minnehaha Gulch and back to Crater Lake. From there, you'll retrace your steps to Maroon Lake and the trailhead, completing the loop.Flora, Fauna, and HistoryThe Four Pass Loop traverses diverse ecosystems, from aspen forests to alpine tundra, and is home to a variety of plant and animal species. The area is rich in history, with the Ute Indians being the original inhabitants. Miners and settlers later came in search of silver and gold, leaving behind traces of their endeavors.Preparation and ConsiderationsDue to the high elevation and remote nature of the trail, it's essential to be well-prepared. Weather can change rapidly, and snow can be present even in summer. High-quality gear, including a map, compass, and GPS device, is recommended. HiiKER can serve as your digital map and guide. Be sure to pack enough food, water, and clothing for the unpredictable mountain conditions.Leave No TraceAs always, practice Leave No Trace principles to preserve the beauty and wilderness of the Maroon Bells-Snowmass area for future generations to enjoy.
