Mountain bike tours explore the gorgeous Coldstream Canyon area of the Park on a 10-mile beginner ride (9am-1pm). California State Park leaders will guide the group to scenic vistas to highlight Railroad Chinese contribution to the transcontinental railroad, indigenous culture, California emigration, and wildlife diversity. Tours are limited to ten riders. Participants bring their own (recently serviced) mountain bikes, helmets, sun protection, food, and water. Tours are free and parking fees apply.
