This route can be ridden either direction. It can be started anyplace along the track, but is shown as a big loop going clockwise, starting and ending at the base of Big Bear ski resort where there is ample parking.
This route is generally an INTERMEDIATE ride, but it includes some very challenging dirt roads and trails. Sections of the SART are extremely sketchy with very serious and hazardous exposure. Caution and skill must be employed here. The section going up Clark's Grade is a category HC climb (if ridden up as described) and will seriously challenge any rider's endurance.
Recommend you ride with a group or at least a buddy and bring plenty of provisions and spares - especially lots of water. Don't forget your camera - there's some incredible views you'll want to preserve.
This is an ALL DAY RIDE. Start this route EARLY to give yourself time to get back to the start before the sun sets.
There are many other trails that can be accessed and explored along this route. Example: This route follows the fastest way back to the start (2N10) after summiting Clark's Grade; however, if a rider has time and inclination they could just as easily ride the Skyline Trail east instead of 2N10 and basically get to the same place.
