The Alpine Loop near Silverton is a backcountry byway, not a casual drive
The Alpine Loop links Silverton to high passes and old mining sites on rough roads that need the right vehicle and are closed by snow much of the year.

From Silverton, the Alpine Loop heads up into the high country toward Lake City and Ouray, passing old mining sites and crossing two high passes, Engineer and Cinnamon. It is a named byway, but the word “byway” can be misleading here.
Much of the loop is a rough mountain road managed by the Bureau of Land Management and the Forest Service. The lower stretches near Silverton can be fine for ordinary vehicles, but the highest sections over the passes call for a high-clearance, four-wheel-drive vehicle. Snow keeps the upper road closed for a large part of the year, often only opening in summer and into early fall.
Why this matters: people sometimes set out expecting a paved scenic drive and find a narrow, rocky shelf road instead. Weather can change fast at over 12,000 feet, and there are no services up top.
If you want to drive the Alpine Loop out of Silverton, check current road status and vehicle requirements with the BLM and the San Juan National Forest before you go.
