Alpine Loop (12,800′), San Juan Range
The Alpine Loop Backcountry Byway is a rugged 4×4 road that winds through the spectacular scenery of the San Juan Mountains, connecting Lake City, Silverton, and Ouray. The Alpine Loop byway traverses passes up to 12,800 feet while showcasing old mines, ghost towns, natural wonders, beautiful wildflowers, and abundant wildlife. Take a 10 minute detour while on the way to Cinnamon Pass to treat yourself to American Basin, one of the most beautiful places in Colorado.
Tackling the loop in its entirety is easily an all-day adventure. However, the main loop is only part of the experience; miles of designated side routes allow visitors to either take a short tour or extend their trip to multiple days. Hurricane (12,730′) and California Pass (12,960′) are two such examples that take you north from the Alpine Loop. For something closer to Lake City, tackle Wager Gulch to the Continental Divide.
