Just north of San Francisco's Golden Gate is Mount Tamalpais. It has redwood groves and oak woodlands with a spectacular view from the 2,571-foot peak. On a clear day, visitors can see the Farallon Islands 25 miles out to sea, the Marin County hills, San Francisco and the bay, hills and cities of the East Bay, and Mount Diablo. On rare occasions, the Sierra Nevada's snow-covered mountains can be seen 150 miles away. Coastal Miwok Indians lived in the area for thousands of years before Europeans arrived. In 1770, two explorers named the mountain La Sierra de Nuestro Padre de San Francisco, which was later changed to the Miwok word Tamalpais. With the Gold Rush of 1849, San Francisco grew and more people began to use Mount Tamalpais for recreation. Trails were developed and a wagon road was built. Later, a railway was completed and became known as "The Crookedest Railroad in the World." It was abandoned in 1930 after a wildfire damaged the line. Facilities and Activities Hiking and Bicycle Trails: More than 50 miles of hiking trails are within the park and connect to a larger, 200 mile long trail system. Friends of Mt. Tam provides hike suggestions and hike schedules on their website. Road bikers are challenged by the infamous seven sisters and the twisting road to the top while mountain bikers can enjoy the Coast View and Dias Ridge multi-use trails as well as park fire trails.

The East Peak Summit features a Visitor Center and the Gravity Car Barn, a small museum of railroad history (open on weekends only). Picnic tables and a fully accessible restroom are also available. The Mountain Theater (AKA The Cushing Memorial Theater) was constructed by the Civilian Conservation Corps in the 1930s. The natural-stone amphitheater seats 3,750 people and features the Mountain Play each spring, produced every year since 1913.
