This loop, which explores the eastern end of the Crafton Hills, is proof that a hike doesn’t have to go into the wilderness to feel rugged and wild. Although the sights and sounds of civilization are always at hand, this route’s dramatic mountain views (of San Bernardino Peak in particular), sharp switchbacks and up-close aerial perspectives on Highway 38 make it more visually interesting than many hikes that are more geographically remote.

From Grape Avenue, take the unsigned trail into a patch of chaparral and climb to a ridge (0.3 miles). Follow it briefly and look for a trail leading downhill to the right. You drop down to a service road, cross it and pick up the trail which climbs to another ridge, providing views of the East Reservoir. The trail merges into a paved service road which you follow a short distance.
Right before the road curves sharply downhill, leave it and follow the trail to a junction (0.9 miles from the start). This is the beginning of the loop, which can be hiked in either direction. By hiking clockwise, as described here, you can knock off the majority of the climbing early on. (The left fork is signed for Zanja Peak; the right fork is signed as the 38 Loop due to its proximity to that highway).

Bear left and head uphill, zigzagging your way across the eastern slope of the Crafton Hills. In addition to the imposing view of San Bernardino Peak and the Yucaipa Ridge, you also get an aerial view of the reservoir and in the distance, if visibility is good, you may even be able to pick out the Palomar Mountains of San Diego County.

After almost a mile of steady climbing, you reach a junction (1.8 miles from the start). This is the high point of the loop. You can extend your trip to Zanja Peak by heading left, but to continue with the loop, take the right fork and begin your descent. On the way down, you get a good view of the eastern San Gabriel Mountains.
The twisting descent follows both sides of a ridge, dropping down into a canyon and coming out at the service road (3 miles). Turn right and follow the road briefly to pick up another trail, which climbs back up to the junction, completing the loop. From here, retrace your steps back to Grape Avenue.

Nice. I had no idea there was a reservoir up there. When ever I visit Oak Glen, I think I should explore some of those trails into the Crafton Hills, but still haven’t made time for that.
Yeah, it’s worth doing if you’re in the area. Thanks for the heads up on the Adventure Pass hikes, I’d been meaning to change those and just finally got around to them today.
