Ride Description

Bonelli park in San Dimas is a multi recreational park that offers camping, boating, hiking, golfing, and of course, mountain biking. It is adjacent to Raging Waters, and it is quickly accessible from any county. There are approximately 9 miles of trail network in our featured loop, most of which circles around the lake and the park. There are also plenty of trails to ride within the center of the park itself if our loop keeps you wanting for more. Be advised that this ride is all sun exposure, and there is plenty of climbing to keep your legs pumping. San Dimas can be a scorcher in the summer so get there early and bring plenty of hydration to avoid heat related injury. There are trail maps available on their website, with trail names, but you will notice signs that only state “Bonelli Park”. Follow these and you’ll be fine. The general idea is to loop around the park in a clockwise motion.
