Bike - The bike course is on multi-use trails within the Granite Bay State Park on Folsom Lake. The course features a fun, challenging combination of twisting single-track, wide double track, rolling cross-country with lots of turn that flow beneath the oak and pine forest. The course is perfect for first-timers and exciting fun for all levels. Please be respectful of other trail users including hikers and equestrian riders in this state park.
