Intermediate Mountain Bike Ride Fremont Loop

Highly experienced mountain bikers can explore one of the most rugged and remote areas of the Irvine Ranch Natural Landmarks from the trails of Fremont Canyon Nature Preserve on this moderately paced intermediate ride.  Fremont Canyon remains one of the most wild places in Orange County, with a diversity of rare plants and animals, and this ride includes natural trail hazards such as sand, tree roots, ruts, and exposed rocks.  PLEASE NOTE: there are multiple very steep climbs, with an approximate elevation gain of 3,500 feet over 19 miles.  This hard ride is for expert adult-only riders in excellent physical condition who will be rewarded with the remote wonders of Fremont Canyon.
