Zanja Peak, the highest point in the Crafton Hills at 3,543 feet, can be reached by several routes. The short but steep approach from Oak Glen Road has already been written up on this site, so on this post we’ll look at the longer route from the west, using the Thunderbird Trail and Hilltop Trail. Except for a very steep push to the summit, most of the hike is at a pleasantly moderate grade.

From the corner of 13th St. and Chapman Heights, head west briefly and pick up the Thunderbird Trail. You cross a small wooden footbridge and begin your ascent, weaving in and out of two shallow canyons. After 1.2 miles of moderate ascent, you reach a four-way junction. Turn right and follow the trail up a ridge. This is not the “official” Crafton Hills Ridge Trail but it’s a more interesting and challenging route. (You can continue straight along the Thunderbird Trail for a short distance to meet the Crafton Hills Ridge Trail, a fire road.)

From the top of the ridge, a steep descent brings you to the fire road. Though the road makes a few switchbacks, you can save a few minutes by following a use trail that continues the steep descent into the valley, passing by a lone oak ideally situated for a resting spot.

After rejoining the fire road, you continue to head east, enjoying good views of Redlands, Mentone and the San Bernardino Mountains on the left and the Yucaipa area on the right. You may get a glimpse of Old Sadddleback behind Box Springs Mountain.
At 3.4 miles, a bench makes another scenic rest spot; you get a good aerial view of Mill Creek and might see cars passing by on Highway 38, far below. At 4 miles, keep an eye out for a break heading sharply uphill. Bear right and climb 0.2 miles, gaining about 250 feet, to the summit.

From here you get a panoramic view of San Bernardino and San Gorgonio; San Jacinto; the Palomars; the San Gabriels and more, pending of course, good visibility. You can retrace your steps or if you’ve set up a shuttle, you can descend to one of several other trail heads.
