The Rio Grande National Forest is filled with riding opportunities for beginner and advanced riders. Several trails are within a couple miles drive from town, and some are specifically listed as multi-use for bikes…not to mention the hundreds of miles of forest service access roads open to cyclists of all abilities. Many trails are multi use - so be prepared for hikers, horses, and ATV’s along the way.

When riding any of the trails available you need to remember that we are at over 8,000 ft. on the valley floor, and you need to be prepared and physically fit before hitting the harder, higher altitude trails. There are numerous well maintained and beautiful trails.


When using any of the trails in the area around South Fork, it is asked that all riders follow the IMBA rules of the trail which are as follows:
    1. Ride on open trails only
    2. Leave No Trace
    3. Control your bicycle
    4. Always yield trail
    5. Never spook animals
    6. Plan ahead
