hello,, if you are out in riverside. there is a 10 square mile area for riding thats always under construction jumps trails and cross country riding for various levels. pretty close to milestone in the riverside area. i ride it almost everyday. its never seen more than a handful of riders at most.
its off mission blvd. and La Rue street just over the railroad tracks once you get over the bridge that goes over the 60 freeway. you can park to the right of la rue street and boom, the trail is right there and takes you all the back to where the tracks and trails are.
