San Pedro Mountain rises above the town of San Rafael on the east side of Marin County bordering San Pablo Bay. This is a mostly forested massif of 4 merging ridges with susequent sub ridges. It sits rather isolated from the rest of the hills and mountains of Marin to the west and south. The main ridge lines define the boundaries of San Pedro Mountain Open Space Preserve to the northwest, Harry Barbier Park to the southwest and China Camp State Park on the east. Fire roads and trails come up from every direction and connect to San Pedro Ridge Fire Road, the main ridge that runs along the top.
With many of the trail heads starting right out of local neighborhoods this is a very popular destination for mountain bikers, hikers and trail runners. San Pedro is great for short hikes and gives you that feeling of "off in the mountains" even though it is largely surrounded by an urban setting.
Access from the south: From Hwy 101 in San Rafael go east on Point San Pedro Rd. Access from the north: Take North San Pedro Road exit east.
These 2 approaches are basically the same road looping around the mountain from central San Rafael to north San Rafael.
The maps in the route section show access points from North San Pedro Rd., China Camp and Point San Pedro Rd.
Gold Hill is the most popular trail head out of San Rafael. It starts out in Harry Barbier Park.

There are too many routes and starting points to spend time covering them on this page. Generally speaking almost all the routes to the top involve roughly 1 to 2 hours round trip with 2 or 3 miles and 900 to 1000 ft of gain. There are also trails that run relatively level around the mountain at different elevations. Below are links to the maps from San Pedro Mountain Open Space and China Camp State Park which pretty much covers the main trails on the mountain.
