Abandoned military sites and sweeping ocean views make for a memorable stroll.
Two abandoned gun emplacements with marvelous ocean views bookend this 4-mile round-trip Marin Headlands hike from Battery Mendell to Battery Townsley. The coastal trek takes you across a lofty, iceplant-covered dune and along a beach that edges a lagoon frequented by large and small waterfowl.
Battery Mendell
After arriving at the parking lot near Battery Mendell (see full directions below), explore that emplacement. Atop a bluff overlooking the Pacific, Battery Mendell (sometimes spelled Mendel) exists in a photogenic state of decay.
Rodeo Beach
Walk north up Field Road to the Battery Alexander parking lot; at its northwestern corner you’ll find a trail that leads across a dune to Rodeo Beach.
Battery Townsley
Enjoy the views of the Pacific to the west and Rodeo Lagoon to the east before continuing north up the hiking portion (a dirt path, as opposed to the paved biking section) of the Coastal Trail to Battery Townsley.
From here you can backtrack directly to Battery Mendell or extend your hike on the 1.5-mile Rodeo Lagoon Trail Loop before returning to Mendell.

Getting Here
Battery Mendell is at the intersection of Field Road and Mendell Road.
By Car
The easiest way to visit the headlands is by car.
If heading north from San Francisco: Just after crossing the Golden Gate Bridge, take the Alexander Avenue exit, and turn left at the first opportunity. (As you make the left turn, you’ll see signs for the Marin Headlands coastal and tunnel routes. Follow the one for the coastal route.) After you pass under U.S. 101, you’ll be heading south back toward the bridge. Just before the bridge, head west (right) up Conzelman Road.
If heading south on U.S. 101 from anywhere in Marin: Take the Alexander Avenue exit (the last one before the Golden Gate Bridge) and immediately turn left, following the brown sign that reads Marin Headlands Coastal Route. In a hundred or so feet, head west (right) up Conzelman Road.
Once on Conzelman Road: Stop at any Conzelman Road vista points that strike your fancy, continuing on Conzelman when it becomes one-way heading west. After 2.3 miles make a left on Field Road, which dead-ends at Battery Mendell.
Tip: If the lot near Battery Mendell is full, you can park at the YMCA (it’s at Conzelman and Field roads) or nearby Battery Alexander.
