San Jose, California
Mount Diablo State Park – Grand Loop
Contra Costa County
As mountains go, Mt. Diablo isn’t particularly tall – only 3,849 feet. However, the unobstructed view from the summit is remarkable. When visibilty conditions are best, you can see almost 200 miles. From the Farallon Islands to the Sierras and from Mt. Lassen to Half Dome. For this reason surveyors used Mt. Diablo’s peak to map out much of Northern California.
We will meet at the Juniper Diablo Valley overlook parking area.
On this hike we will enjoy the full panorama as we make a complete loop around the top of the mountain before ascending to the summit. We start off from Juniper overlook (2940’) down Deer Flat Rd. and Meridian Ridge Rd. (2000’). We then go up Bald Ridge Trail and near Prospectors Gap (2955’) we will have our meeting. After, we take North Peak and Summit Trails to the Summit (3849’). We then descend on Juniper Trail.Level: 3.5 - Miles: 6.25 - Elevation change: 1849' - Hosts: Troy and Amy
