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.

Part of the coastal defenses along Coastal Trail, latest remnants here date from the WW II and early cold war era.

This is a great gravel road that takes you from the summit of Mount Tam to West Point. The road is wide and not very technical, but the views south across the foothills to Muir Woods are fantastic.

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.

I've been coming here for 11 years. It's always my first contact with the ocean after landing at SFA. The smell of eucalyptus and the salt-soaked air

After looping around West Point the Railroad Grade trail snakes through open and tree-lined sections with fun curves.
