Alpine Loop National Back Country Byway
These back roads in the San Juan Mountains were once used to haul mining equipment and supplies to high-elevation silver and gold mines. The extracted ores were then hauled out to the mills and train depots, helping to fuel the American expansion of the late 1800s and early 1900s.
Now a National Back Country Byway, the Alpine Loop offers a look into that era, with relics of the mining boom scattered along the way. You'll see ghost towns, cabins, mills, and mine sites, with interpretive signs that explain the significance of this road to the development of the American West.
Starting and ending in Lake City, the Loop winds through canyons, up into high alpine valleys, and above tree line to engineer Pass and Cinnamon Pass, each more than 12,000 feet in elevation. From either pass, the roads drop into the ghost town of Animas Forks. From there, side trips to the historic towns of Silverton and Ouray
are possible.
The Alpine Loop is about 65 miles around, so plan on spending at least a day to explore it.

Keep in mind that the Alpine Loop is narrow and twisty; drive slowly. Make sure you have a full tank of gas, food, solid footwear, raincoats and jackets with you.
ATVs and four-wheel drive vehicles are available for rent from local businesses.
