The trip to Potato Mountain (elevation 3,422) is a nice, moderate hike that provides a good variety of scenery. Even if the Inland Empire is covered in smog, the quiet trip up through Evey Canyon and the up-close views of the Ontario/Cucamonga Ridge are enjoyable.

From Mt. Baldy Road, pass the yellow fence and enter Evey Canyon and the Herman Garner Biological Reserve, operated by nearby Pomona College. You dip down into the oak-lined canyon, and then the trail begins ascending at a moderate grade. A seasonal stream runs through the bottom of the canyon. As you ascend, the trees thin out but the canyon’s steep walls block out most of the sun. You get a few views of Sunset Ridge to the north, dotted with some antenna structures.

At 1.4 miles, you reach a T-junction. You can reach the popular Claremont Hills Wilderness Loop by heading right, but to reach Potato Mountain, head left. You make another quick descent to a saddle, where you can see the summit of Potato Mountain to the right and Cucamonga Peak’s characteristic pyramid shape to the left in the distance. Clinging to the north side of the mountain, the fire road ascends, providing nice views of the canyon below. After a hairpin turn to the right, you arrive on Potato Mountain’s flat summit.

If visibility is good, the view here is one of the best in the L.A. area. From east to west, you may see San Gorgonio, San Jacinto, the Palomar Mountains, the Santa Anas, Catalina Island, the Palos Verdes Peninsula, downtown Los Angeles, the Hollywood Hills and the Santa Monica Mountains.

    1. You can reach the Claremont loop by heading right at the T-junction 1.4 miles up (instead of left, which takes you to the summit.)
