Tips from the Community

Gianmaria
March 15, 2026, View of the City Skyline

Climbing up Mount Tamalpais, you'll find many great spots for admiring the scenery, but this one particularly struck me because, almost immersed in nature, you can see the city skyline in the distance. I found it so moving that I stopped my bike and stood there contemplating the landscape for a few minutes. The climb is a bit steep, but it's definitely worth it!

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.

Fern Creek Trail is an excellent trail – scenic views, technical underfoot, loose at times, mind your head on low branches. Close to the bottom there have been caribou land slips and tree falls over the years that have meant the trail is rerouted up and over ever so slightly. Absolutely adore this trail.

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.
