Venture into the heart of Colorado’s San Juan Mountains on the Alpine Loop Back Country Byway, a 63-mile adventure that transports you through some of the most dramatic alpine scenery in the American West. This rugged backcountry route climbs through historic mining districts, crosses two spectacular mountain passes above 12,000 feet, and winds past ghost towns frozen in time.

The journey connects Lake City, Silverton, and Ouray—three charming mountain communities—while traversing Engineer Pass and Cinnamon Pass through terrain that feels wonderfully remote. Along the way, you’ll encounter wildflower-carpeted meadows, cascading waterfalls, abandoned mine structures, and panoramic views that stretch across countless peaks.

This isn’t your typical scenic drive. High-clearance 4WD vehicles are essential, adding an element of adventure that rewards intrepid travelers with access to landscapes most visitors never see. Stop at the Animas Forks ghost town, marvel at the engineering of century-old mining roads carved into cliffsides, and watch for marmots sunning themselves on rocky outcrops.

Best time to visit: Late June through September, when passes are snow-free.

Allow: A full day to properly explore, photograph, and soak in the alpine majesty. This is a drive meant to be savored, not rushed.
