"This route commences south from Ouray on the Million Dollar Highway, US 550. If you wish to avoid the hardest section of Engineer Pass Road, the route can be commenced at Silverton. Special Attractions: Part of the historic Alpine Loop, with many famous mining sites; Driving through the twenty-foot deep channel in the snow early in the season. High-clearance 4WDs are recommended, though most stock SUVs are acceptable. Expect a rough road surface with rocks larger than 6 inches, but there will be a reasonable driving line available. Patches of mud are possible but can be readily negotiated; sand may be deep and require lower tire pressures. There may be stream crossings up to 12 inches deep, substantial sections of single-lane shelf road, moderate grades, and sections of moderately loose road surface."

"This trail, combined with Cinnamon Pass, constitutes the famous Alpine Loop. It is an exhilarating trip for drivers of all experience levels. There are many mines and points of historical interest along the route. The east side of the trail follows Henson Creek where you’ll find excellent places to camp and fish. The entire route is open to ATVs. You’ll find staging areas on the west, south and eastern entry points. Unlicensed vehicles must display an OHV permit and riders must possess a valid drivers license or vehicle operator’s license. Ouray and San Juan Counties require proof of liability insurance for unlicensed vehicles. Most of the route is easy, but there are still a few narrow, steep places on the west side of the pass that will get your attention. The trail climbs to an elevation of 12,800 ft. Caution should be used at all times especially in wet weather. Any 4x4 with moderate ground clearance and low-range gearing can do it."

One of the best 360 views that you can drive to. The trip from Lake City side is great. The side trip to Ucompahgre Peak is great with dispersed campsites everywhere.

Myself and Mrs. KFitz rented a Rubicon in Lake City and drove the Loop for the fourth time. The views are very spectacular, and we will do it again every chance we get. It's best to plan for a full day trip to be able to stop and "smell the (mountain) roses."

One of the most beautiful and scenic drives I have ever been on. We took the Animas Forks trail Northeast out of Silverton. The views are breathtaking and the climb is exciting. The difficulty of the trail is only intermediate but does require 4WD. Although the trail itself is well maintained a wrong move could still be deadly as the climb is mostly on a single lane shelf road.

If you are OK with the heights then this is a MUST DO if travelling to the Silverton area.
