This exposed trail gets firecracker hot in summer, so we recommend hiking it before then. The trail also gets steep, so wear shoes with good tread. Park at Juniper Campground off Summit Rd. There are two paved roads; walk down the one on the right to Deer Flat Rd. Continue on Deer Flat Rd. for 1.5 miles until you reach Deer Flat. Go right on Meridian Ridge Rd. Continue on Meridian Ridge Rd. for about a mile through Murchio Gap and up to Prospector’s Gap Trail (an Eagle Peak side-trip can be made at Murchio Gap). Continue up the Prospector’s Gap Trail for 1.3 miles until you reach Prospector’s Gap (a North Peak side-trip can made here). Go right, up the North Peak Trail toward Mount Diablo’s summit. Reach Devil’s Elbow after 1 mile and go right, then up the Summit Trail to the lower summit parking lot. Walk to the back of the lot and descend the Juniper Trail 1 mile back to your car. No dogs.
