East Ridge Bell Canyon Loop Trail is a 6.8 mile moderately trafficked loop trail located near San Juan Capistrano, CA that features beautiful wild flowers and is good for all skill levels. The trail offers a number of activity options and is accessible year-round. Horses are also able to use this trail.
These are many trails that loop around within "Caspers Wilderness Park" off the Ortega HWY. Google their website for a map of all these trails (or see link below). All are located within the campground, I think day use access is free. Great hiking, lots of horses and some mountain biking.
