Mount Tamalpais State Park and Watershed

Mount Tamalpais (or "Mount Tam" as it is known locally) is the highest and most distinctive mountain in Marin County. The mountain actually has two peaks: the East Peak, its highest point, rises to 2,571 feet, while the West Peak is only slightly lower at 2,563 feet. The mountain is clearly visible from the city of San Francisco, most of Marin, and the East Bay region. The majority of the mountain consists of protected public lands, including Mount Tamalpais State Park, Muir Woods National Monument, and the Mount Tamalpais Watershed. It adjoins the Golden Gate National Recreation Area (GGNRA) as well as several Marin County Open Space Preserves. This provides nearly 40 miles of continuous publicly accessible open space stretching from the Golden Gate northward to Bolinas.
Mount Tamalpais State Park and Watershed is a trail running and hiking paradise, with over 100 miles of trails and fire roads, ranging from sea level to over 2,500' at the summit of Mount Tam. The trails to the east of the summit are primarily fire roads that were the birthplace of mountain biking. To the west of the summit, challenging singletrack runs from the summit all of the way to the beach. To the south, the area connects to Muir Woods and the Marin Headlands area of the GGNRA. To the north, the area connects to the Bolinas Ridge area of the GGNRA.
There are too many trailheads for the Mount Tamalpais area to list all of them here. The Favorite Runs described below start from the town of Stinson Beach. Other possible starting locations for runs include the Mountain Home Inn, the town of Mill Valley, or a multitude of other locations along Highway 1 or the Panoramic Highway

History of the Old Railroad Grade

The Mount Tamalpais & Muir Woods Railway was a scenic tourist railway operating between Mill Valley and the east peak of Mount Tamalpais. The railroad, which was in operation from 1896 through 1930, was powered by steam locomotives. Billed as the "Crookedest Railroad in the World," the line was renowned for its steep and serpentine route, winding through picturesque terrain to a mountaintop tavern that provided striking views of the Bay Area.
Despite its popularity, the railway met its ultimate demise following a devastating fire in 1929, accompanied by diminished ridership resulting from increased automobile use and the Great Depression. Today, the Old Railroad Grade Fire Road follows the upper four miles of the original railway and provides users a gentle route to the peak.

Favorite Run #1: Stinson to Pantoll loop (7.3 mi, ~1600' elevation gain)
This run starts from Stinson Beach and ascends the spectacular Steep Ravine Trail through a stunning redwood forest. Along the way you will climb the infamous 10-foot ladder! After a stop at Pantoll Ranger Station, the route follows the Matt Davis Trail along the ridge and then down dozens of steps to return to Stinson Beach.
You can park anywhere in town for this run, but our favorite place to start is Stinson Beach State Park which has bathrooms, drinking water, and a great beach to hang out on after your run! To begin the run, head away from the beach and through the gate that leads to Arenal Avenue. Turn right on Arenal Avenue and keep going until it ends at Highway 1.

Favorite Run #3: Mt. Tam Super Loop (26.0 mi, ~5100 feet elevation gain)
This run combines the all of run #1 and #2 into one massive loop, covering a ton of ground both in Mt. Tamalpais SP as well as Mt. Tamalpais Watershed. The route has it all, lakes, peaks, redwoods, waterfalls, easy fire roads, flowing single track, and even some short sections of rocky technical trails. If you want the full Mt Tamalpais experience, this run is for you.
Best to do this run in the Fall, Winter or Spring. It can get quite warm on this run and much of the end of it is exposed to sunlight so you'll be finishing your miles in the heat of the day without any shade Thankfully water is fairly available on this route, but some water stops may or may not be available depending on the time of year. Starting off of Lagunitas Road in the Mt. Tamalpais Watershed, the directions to the start of the run are quite different from the others on this page, so just be aware of that. |
