Mountain bike riding has become one of the more popular recreational activities enjoyed by visitors to Big South Fork. Currently at Big South Fork there are several trails which have been designed, built and are maintained by the Big South Fork Mountain Bike Club. In addition to bike only trails, mountain bikes are allowed on highway edges, back country roads and horse trails. This combination provides bikers of all skill levels with miles of trail options including:
- Duncan Hollow Loop
- Collier Ridge Loop
- West Bandy Trail
- Grand Gap Loop.
