Potato Mtn - Wilderness Trail is a 5.8 mile out and back trail located near Claremont, California that offers scenic views. This track is connectable from the Claremont Loop or Marshall Canyon Trail. I understand you can head up Every Canyon as well, but heard you need a pass (free) to get on the trail.

This trail is primarily used for hiking, road biking & trail running. Connecting from Marshall Canyon Trail will provide quite a workout, as it's 8 to 9 miles of climbing. I wouldn't recommend this on a hot summer day as there is little respite from the sun. If coming up the Cobal Canyon - Claremont trail, you're looking at 5 to 6 miles. The trail is all fireroad and not very rocky at all. Additionally, the last dig up to the peak is a pretty good stretch and a bit steep. It's really the only tough section.

Once at the top the tradition is to leave a spud with your name on it at the concrete cylinder at the peak. Once up there, you get some good views of the Pomona Valley and Pacific Ocean on clear days.

Rewarding climb with awesome view at the top of Potato Mountain. Trail can be steep and loose in a couple sections. Actual riding is just a typical semi loose fire road with nothing to remember. Good adventure ride with a awesome spot at the top to enjoy the breath-taking views. Jul 5, 2015

On a business trip and rented a bike from Incycle in San Dimas (just a couple miles away from the trailhead). Did the ride through Marshall Canyon to the peak of Potato Mountain. The description doesn't lie, it's 8 or 9 miles of climb, climb, climb until you reach the top. Incredibly beautiful views all the way up. Incidentally, the trail is also shared with horses - they get the right of way at all times. Coming down from Potato Mountain all but makes up for the pain of the climb. Fast and fun. Apr 21, 2016
the climb is DRAINING! but the top is a cool place to hang out not very technical and the downhill is just a fire road but if you want to exercise and improve your climbing ability its cool! just be aware its not a well shaded trail and gets very hot in the summer! Jul 3, 2017
