Rim Nordic’s Mountain Biking territory includes 15 miles of single-track paths
and fire roads, from beginner to advanced levels. It is operated under a special use permit from the US Forest Service located in the San Bernardino National Forest. In winter they offer cross-country skiing and snowshoeing, and in summer, they are open for mountain bike riding on a challenging trail system, weekends only starting Memorial Weekend thru Labor Day. They regularly host bicycle racing events sanctioned by USA Cycling. They even offer free Kid Races on the same day as the adult races for children 11 and under. The park has a Retail Shop with clothing, new and used equipment, and a Snack Bar.
