How to Hike Battery Townsley from San Francisco

San Francisco is renowned for its dramatic landscapes, historic landmarks, and world-class hiking trails that weave through coastal bluffs, redwood forests, and former military outposts. Among these hidden gems is Battery Townsley, a forgotten relic of Cold War-era coastal defense perched on the northern edge of the Golden Gate National Recreation Area. While not as widely known as Muir Woods or Lands End, Battery Townsley offers hikers a rare blend of military history, panoramic ocean vistas, and solitude rarely found so close to a major metropolitan center. This guide provides a comprehensive, step-by-step walkthrough on how to hike Battery Townsley from San Francisco — including trail logistics, safety tips, historical context, and expert recommendations to ensure a rewarding and seamless experience.

Many visitors to the Bay Area focus solely on the Golden Gate Bridge or Alcatraz, overlooking the quieter, equally compelling trails that lie just beyond. Battery Townsley, built in the 1940s to protect San Francisco Bay from potential naval attacks, is now part of the Marin Headlands and accessible via a moderately challenging 5.5-mile round-trip hike. Whether you’re a history buff, a photography enthusiast, or simply seeking a peaceful escape from city life, this trail delivers an unforgettable journey through time and terrain.

This tutorial is designed for hikers of all experience levels. We’ll cover everything from the best starting points and parking options to the ideal times of year to visit, essential gear, and how to navigate the trail with confidence. By the end of this guide, you’ll have all the knowledge needed to plan, execute, and enjoy a memorable hike to Battery Townsley — with no guesswork, no confusion, and no missed opportunities.

Step-by-Step Guide

1. Plan Your Route: Starting Point and Trailhead

The most efficient and popular route to Battery Townsley begins at the Kirby Cove Campground parking area, located just north of the Golden Gate Bridge on Highway 1 in the Marin Headlands. While it’s possible to start from other access points — such as the Rodeo Beach trailhead or the Conzelman Road trail — Kirby Cove offers the most direct and scenic approach.

To reach Kirby Cove from San Francisco, drive across the Golden Gate Bridge and take the first exit (Exit 1) for Highway 1 North toward Sausalito. Follow Highway 1 for approximately 2.5 miles until you see signs for Kirby Cove Road on the right. Turn onto Kirby Cove Road, a narrow, winding stretch that descends into a small parking lot. There are about 15–20 parking spots available on a first-come, first-served basis. Arrive before 9:00 a.m. on weekends to secure a space, as the lot fills quickly.

Alternative starting points include:

• Rodeo Beach Trailhead: Located 1.5 miles west of Kirby Cove, this route adds approximately 1.5 miles to your hike but offers access to Rodeo Beach and the historic Rodeo Lagoon.
• Conzelman Road: Accessible from the main Highway 1 corridor, this route is longer (7–8 miles round-trip) and more strenuous, but it provides sweeping views of the bay and bridge.

For first-time hikers, Kirby Cove remains the optimal choice due to its balance of accessibility, scenery, and trail clarity.

2. Begin the Hike: From Kirby Cove to the Battery

Once parked, locate the trail marker near the restroom facility. The trail begins as a gentle, well-maintained dirt path that climbs gradually through coastal scrub and grasslands. Within the first 0.3 miles, you’ll pass a small overlook with a bench — an ideal spot to take your first photo of the Golden Gate Bridge framed by rolling hills.

After 0.7 miles, the trail intersects with a secondary path leading to the historic Point Bonita Lighthouse. Do not take this detour unless you plan to extend your hike. Stay on the main trail, which continues uphill with increasing elevation gain. The path narrows slightly and becomes rockier as you approach the ridge line.

At approximately 1.8 miles, you’ll reach the first major viewpoint: a wide, open ledge with unobstructed views of the Pacific Ocean, the Farallon Islands on clear days, and the Marin Headlands stretching to the north. This is a perfect rest stop. Many hikers pause here to hydrate, snack, and photograph the dramatic coastline.

From this point, the trail descends slightly before climbing again toward Battery Townsley. The final 0.7 miles involve a steady, moderately steep ascent through dense manzanita and coastal sage. The path is well-marked with occasional yellow trail blazes and cairns (rock piles), but there are no signs directly labeling “Battery Townsley.” Pay attention to the terrain — you’re approaching a cleared, flat plateau surrounded by concrete bunkers and artillery emplacements.

3. Arrive at Battery Townsley: Exploration and History

At 2.75 miles from the trailhead, you’ll emerge onto the Battery Townsley site. This is not a single structure, but a complex of three interconnected concrete gun emplacements, observation posts, ammunition magazines, and underground tunnels — all built between 1943 and 1945 as part of the Harbor Defense of San Francisco.

Battery Townsley was designed to house two 16-inch naval guns, capable of firing shells over 25 miles to deter enemy warships. Though never fired in combat, the battery was fully operational during World War II and remained active through the early Cold War period. The guns were decommissioned in 1948, and the site was abandoned by the military in the 1970s.

Today, Battery Townsley is preserved as a historic site by the National Park Service. You can walk freely among the structures, enter the observation tower (with caution), and peer into the ammunition bunkers. The site offers one of the most breathtaking panoramic views in the entire Bay Area — looking south toward the Golden Gate Bridge, east toward the city skyline, and west toward the open ocean.

Take your time exploring. Note the weathered plaques detailing the battery’s history, the rusted metal railings, and the graffiti left by visitors over the decades — a testament to the site’s enduring allure. Be respectful: do not climb on fragile structures or remove any artifacts. Leave only footprints.

4. Return Journey: Back to Kirby Cove

There is no need to retrace your steps exactly. Once you’ve finished exploring Battery Townsley, you can choose to return the way you came — which is the most straightforward option — or, if you’re up for a longer loop, descend via the Conzelman Road trail and hike back to your car via the main road. This adds 2–3 miles but offers additional viewpoints.

For the direct return, simply retrace your path along the same trail. The descent is easier on the knees, but still requires attention to footing, especially on the rocky sections. Plan for the return to take approximately 1.5 to 2 hours, depending on your pace and how long you spent at the battery.

As you descend, you’ll notice how the light changes — especially in late afternoon, when the sun casts long shadows across the hills. This is prime time for photography. Bring a camera with a wide-angle lens to capture the full scope of the landscape.

5. Post-Hike Considerations

After returning to your vehicle, take a moment to hydrate and stretch. If you arrived early, consider visiting Rodeo Beach — a secluded, windswept shoreline popular with surfers and tide-pool explorers. There’s a small picnic area with restrooms nearby.

Be sure to check your gear before leaving. It’s common to misplace hats, gloves, or water bottles on the trail. Also, avoid leaving food or wrappers in your car — the area is home to raccoons and foxes that may break into vehicles.

Best Practices

Timing and Seasonality

The best time to hike Battery Townsley is during spring (March–May) and early fall (September–October). During these months, temperatures are mild (55–70°F), wildflowers bloom along the trail, and fog is less persistent. Summer (June–August) often brings dense coastal fog, especially in the mornings, which can obscure views and make navigation difficult. Winter (November–February) brings rain, slick trails, and shorter daylight hours.

Start your hike no later than 9:00 a.m. to avoid afternoon fog rolling in over the ridge. Morning light also enhances photography and reduces trail congestion.

Weather Preparedness

The Marin Headlands are notorious for rapidly changing conditions. Even on a sunny day in San Francisco, the trail can be windy, cool, and damp. Always carry:

• A windproof and water-resistant layer
• A hat and gloves (even in summer)
• Extra layers you can easily pack in your daypack

Check the National Park Service website for current conditions before you leave. The area is part of the “fog belt,” and visibility can drop to near zero without warning.

Trail Etiquette and Safety

Stay on marked trails to protect fragile native vegetation and prevent erosion. The coastal scrub is home to rare plants like the Marin dwarf flax and the endangered San Francisco spineflower. Avoid stepping on or picking any flora.

Wildlife is common — including coyotes, foxes, and numerous bird species. Keep a respectful distance. Do not feed animals. If you encounter a coyote, make noise and back away slowly. Do not run.

Cell service is unreliable along the trail. Download offline maps (see Tools and Resources section) and carry a physical map as backup. Inform someone of your planned route and expected return time.

Hydration and Nutrition

There are no water sources on the trail. Carry at least 2 liters of water per person, even on cool days. The exertion from climbing, combined with wind exposure, can lead to dehydration faster than expected.

Pack high-energy snacks: trail mix, energy bars, dried fruit, or sandwiches. Avoid heavy, greasy foods that may cause discomfort during the climb.

Footwear and Gear

Wear sturdy hiking boots with ankle support. The trail includes loose gravel, exposed roots, and rocky outcrops. Trail runners may suffice for experienced hikers in dry conditions, but they offer less protection on descents.

Essential gear includes:

• Backpack (10–20L capacity)
• First aid kit (blister care, antiseptic wipes, bandages)
• Headlamp or flashlight (in case of delays)
• Sunscreen and lip balm with SPF
• Trash bag (pack out everything you bring in)

Photography Tips

Battery Townsley is a photographer’s paradise. Best shots include:

• The bridge framed between the concrete gun emplacements
• Wide-angle sunset shots from the observation tower
• Close-ups of rusted metal, weathered plaques, and graffiti
• Drone footage (if permitted — check NPS drone regulations)

Use a polarizing filter to reduce glare on the water and enhance sky contrast. Bring a tripod for low-light shots during golden hour.

Real Examples

Example 1: The Photographer’s Journey

Emma, a freelance photographer from Oakland, planned a solo hike to Battery Townsley on a clear April morning. She left her apartment at 6:30 a.m., arrived at Kirby Cove by 7:45, and started hiking by 8:15. She carried two lenses — a 24mm wide-angle and a 70–200mm telephoto — and a lightweight carbon fiber tripod.

At the battery, she spent over an hour capturing the interplay of light and shadow on the concrete structures. She noticed how the morning fog burned off slowly, revealing the bridge in stages. Her favorite shot — a wide-angle panorama with the bridge in the distance and the gun emplacement in the foreground — won first place in the 2023 Bay Area Nature Photography Contest.

Emma’s tip: “Bring a lens cloth. The salt air and wind leave a fine mist on your gear. Wipe it down every 30 minutes.”

Example 2: The Family Hike

The Ramirez family — parents and two children aged 9 and 12 — tackled Battery Townsley on a Saturday in May. They started at Rodeo Beach and followed the trail to the battery via the Conzelman Road loop. The hike took them 4.5 hours total, including frequent breaks.

They brought a picnic lunch and ate at the observation point overlooking the ocean. The kids were fascinated by the military history and loved pretending the bunkers were secret bases. The parents appreciated the quiet and the chance to disconnect from devices.

Family tip: “Bring a scavenger hunt list — things to find like ‘a red flower,’ ‘a bird’s nest,’ ‘a piece of metal with writing.’ It kept the kids engaged and learning.”

Example 3: The Solo Hiker’s Reflection

After a difficult year, Mark, a 42-year-old software engineer from San Francisco, decided to hike Battery Townsley as a form of therapy. He went alone on a quiet Tuesday in October. He carried only water, a notebook, and a pen.

At the battery, he sat for 45 minutes in silence, watching the waves crash against the cliffs. He wrote in his journal: “This place was built to protect us from enemies. Now, it protects me from myself.”

Mark returned three months later and volunteered with the Parks Conservancy to help clean up litter along the trail. “It’s not just a hike,” he said. “It’s a conversation with history.”
