June 21, 2025, Mount Tamalpais East Peak and Visitors Center

Mount Tam East Peak offers some of the most majestic views north of the bay. From this vantage point, you can see all of Marin, along with Point Reyes to the north and Oakland and San Francisco to the south. The stunning panoramic vistas make the journey well worth the effort. There are restrooms and picnic tables, ideal for a snack or lunch while you capture some incredible photos.

Often busy on weekends, this is a great spot to take moment before/after summiting Mt Tam. There are spigots to fill up water and bathrooms that are open during park hours. The parking lot is very close for those that drive up. There is access to MANY trails for those on foot/bike.

Pantoll Road is a beautiful, mostly paved route through Mount Tamalpais State Park, connecting the Panoramic Highway to Ridgecrest Boulevard. It winds closely along the curves of the hillside, with some shade from the trees in some spots. There are fantastic views along the way of San Francisco and the Marin Headlands, with incredible viewpoints over the Pacific coastline.

This tidal sanctuary runs along the Mill Valley-Sausalito Pathway and the Charles F. McGlashan Pathway. More than 400 species of migratory birds rest here after their long flights, and if you pass through in the early morning or late evening, the sunrises and sunsets reflect beautifully on the surface of this 106-acre marsh.
