Alpine Loop Back Country Byway | Colorado

The Alpine Loop Back Country Byway (BCB) offers a rugged, immersive backcountry experience in Colorado's San Juan Mountains. This 4x4-only road traverses high alpine terrain up to 12,800 feet, connecting the historic towns of Lake City, Silverton, and Ouray. Along the way, visitors encounter sweeping vistas, abundant wildlife, vibrant wildflowers, and relics of the region's mining past — old mines, ghost towns, and natural wonders set against thrilling geography.

Tackling the full loop is easily an all-day experience. But the main loop is only part of the adventure — miles of designated side routes let visitors take a short tour or extend their trip over multiple days. The Alpine Loop embodies both adventure and education, offering an intimate view of Colorado's natural and cultural heritage.

Plan Ahead

The Alpine Loop is a true backcountry experience, and preparation is essential:

• Tell someone your travel plans before you go, and do your homework ahead of time
• Bring plenty of water, food, and fuel to reach your destination
• Don't rely on electronics — cell phones and wireless devices do not work in most areas of the Alpine Loop
• Download or print hard-copy maps before your trip, since you won't be able to pull them up on the road

For more information, contact the Gunnison Field Office or see the Alpine Loop brochure.

Byway Designation

The Alpine Loop is designated as a Type III BLM Back Country Byway, though some segments may qualify as Type I or II depending on road conditions and access. It is also recognized as a Colorado State Scenic Byway.

The byway is valued for its cultural, scenic, educational, historic, and wildlife-related intrinsic qualities. It has not undergone a change in byway type since its original designation. Management objectives across overlapping designations — including the state scenic byway status and tribal conservation agreements — are largely compatible with the goals of the BLM's BCB program.
