Four Pass Loop - West Maroon to Buckskin

ALERT: Due to recent bear activity, bear canisters are required for all backpackers in the Maroon Bells-Snowmass Wilderness. The famous Four Pass Loop backpacking route within Maroon Bells – Snowmass Wilderness is an international treasure. This 26 mile (42 km) circuit climbs over four mountain passes higher than 12,000ft, past clear alpine lakes and among the rugged Elk Range peaks. Thousands of people every summer make the journey to see these sights. Make sure to plan ahead and know before you go! Early summer snowmelt makes the river crossing perilous and deep snow persists on the passes until late in the summer. Sudden thunderstorms can catch travelers exposed far from the cover of tree-line in mid-summer and snow fall returns to the high country early. Please observe all recommendations and regulations to help the US Forest Service protect this unique experience and wild landscape for all.
