Tips from the Community

May 13, 2026, Battery Townsley

Batterij Townsley is a place where nature and history meet. As you climb along the rugged cliffs of the Marin Headlands, the old coastal defense slowly emerges from the landscape. Once at the top, a panorama opens up that will leave you speechless: the Pacific Ocean, the Golden Gate Bridge, and the endless horizon. The abandoned bunkers and tunnels give the place a mysterious atmosphere, as if time has stood still here. A perfect stop to enjoy, wander, and completely immerse yourself in the view.

The park pays homage to a 19th-century fishing village of Chinese immigrants who harvested shrimp from the bay. Much of the village has been preserved, and for a couple bucks you can pay to enter and explore the old town and pier.
