Webb Canyon has been a local favorite for three decades of riding. It has seen many changes just as the sport of mountain biking has. Webb isn't a single trail anymore but a series of downhill runs intermixed with jumps and (vandals permiting) wooden stunts. I would suggest for the a riders first visit to the area to take the option 1 parking area and hike the various routes that descend Webb. For most riders Webb is a shuttling downhill run. People usually park at the option 2 site and head over to the canyon. The Webb trail system can be linked with Johnson's Pasture and the Wilderness Loop. In this the spring this is area is covered in beautiful green wavy grass.
Take the 210 Freeway to the Towne Ave. exit in Claremont. Turn north onto Towne, the mountains are north at this point, and drive to Baseline Ave.
Option 1: Go straight to the end of Towne, less then a quarter mile and park along the road outside the church gates.
Option 2: Turn right onto Baseline and head east to the first light, Mountain Ave. Turn right or north onto Mountain and take it to its end passing through nice hillside homes. At the end of Mountain turn right at the last street and drive to it's end and park in front of the houses.
When to BikeYou can ride Webb Canyon year round, the only closures are dur to wildfire which happen a couple of times a decade.
