Rating: Moderate. A 3.8 mile loop with total climb of 1000 feet beginning at the Juniper Trail. Follow Juniper trail, contouring south along the western slope of the mountain, to the Summit Trail then take Summit Trail toward the summit (you will have to maneuver across a debris parking lot to locate the continuation of the Juniper Trail leading to the Summit Trail.)

Please wear sturdy hiking shoes and bring two quarts of water, snacks, and lunch in a small backpack.

Trail Description:

 Trailhead: Begin hike at campsite #17 turning left on Juniper Trail. Facilities are at Juniper Campground, lower Summit Parking Lot, and at the Summit Museum .

 First leg (Juniper - Pioneer) follows the top of the landslide topography, which rings the main peak, a steep grassy savanna, a showplace for poppies in spring. Second leg to summit penetrates chaparral areas in various stages of post-fire development; fine stands of buckbrush (very aromatic in early spring), and grey pines. Third leg (Juniper Trail) follows dramatic upper reaches of Moses Rock Ridge (Franciscan rock outcrops, dwarf wildflowers), plunges into oak-laurel forest, survivor of many fires.
