the trails start from various points on the mountain foothills. There are many private large properties, so dont jump fences or trespass. There are virtually hundreds of ways to descend. Many of the singletrack has excellent jumps and rocks to roll over. This is strictly a downhill adventure, so an extra vehicle at the bottom of Pachea Trail is an easy way to hit the hills for the majority of the day.
Interstate 15 to Highway 74 East to Hemet. Hwy74 in Hemet is Florida Ave. Take Florida to Gerard St. Gerard St south towards Ramona Bowl Amphitheater. Take right on Pachea Trail Rd. Follow road to the top where it deadends. Turn around and go down the street past the No Trespassing/Fire Zone signs and find a parking spot. Ride back to the top of the hill to the top half of the trails.
