Step-by-Step Guide
By the end of this section, you will know exactly how to reach Battery Spencer, Battery Godfrey, and other key artillery positions near the Golden Gate Bridge. These sites are often mistakenly grouped under vague names like “Battery Construction 140,” but they are distinct, well-documented, and accessible via established trails.
Step 1: Choose Your Starting Point
The most common and convenient starting point for hiking to the coastal batteries is the Golden Gate Bridge Welcome Center, located at 1501 Fort Point Ln, San Francisco, CA 94129. This visitor center sits directly beneath the southern end of the Golden Gate Bridge and offers restrooms, parking, maps, and interpretive exhibits.
Alternative starting points include:
- Crissy Field – A former military airfield turned scenic park, offering a flat, paved 1.5-mile walk to the bridge’s southern end.
- Fort Point National Historic Site – Accessible via the same road as the Welcome Center, this 19th-century masonry fort is worth exploring before ascending.
- Park Presidio and the Golden Gate Park entrance – For those coming from the south side of the city, this route offers a longer but more scenic approach.
For most hikers, especially beginners, the Welcome Center is the ideal launchpad. It provides clear signage, parking (paid), and immediate access to the trail network leading to the batteries.
Step 2: Begin the Trail to the Bridge
From the Welcome Center, follow the paved pedestrian path westward toward the Golden Gate Bridge. The path is flat, well-maintained, and clearly marked. You’ll pass under the bridge’s southern anchorage and begin to see the iconic red towers looming ahead.
After approximately 0.3 miles, you’ll reach the pedestrian walkway on the bridge itself. Do not walk across the bridge unless you intend to go all the way to Sausalito. Instead, look for the trailhead on your right, just before the bridge’s main support tower. This is the Battery Spencer Trailhead, marked by a small wooden sign and a set of stairs ascending the hillside.
Step 3: Ascend the Battery Spencer Trail
The trail to Battery Spencer is steep, narrow, and roughly 0.6 miles long with an elevation gain of about 500 feet. It is unpaved and consists of packed earth, gravel, and stone steps. Hikers should wear sturdy footwear and carry water.
The path winds upward through coastal scrub, offering intermittent views of the bridge, the Pacific Ocean, and the Marin Headlands. As you climb, you’ll pass several interpretive signs detailing the history of coastal defense in the area. The trail is well-trafficked, so you’re unlikely to get lost.
At the top, you’ll emerge onto a flat, open plateau with a sweeping 180-degree view of the Golden Gate Bridge, the Marin Headlands, Alcatraz, and the Pacific Ocean. This is Battery Spencer. It was constructed in 1943 as part of World War II coastal defenses and housed two 155 mm guns capable of firing 9-mile shells toward enemy ships.
Take time to explore the concrete emplacements, observation posts, and remnants of the gun crew barracks. The view here is arguably the most photographed in the Bay Area—perfect for photos, quiet reflection, or simply enjoying the breeze.
Step 4: Continue to Battery Godfrey (Optional)
If you have additional time and energy, continue hiking north from Battery Spencer along the Battery Godfrey Trail, a less crowded but equally rewarding path. This trail is marked by a faint dirt path heading uphill to the left of Battery Spencer’s main platform.
Battery Godfrey, built in 1942, was designed to support Battery Spencer with additional firepower. Today, it features two large gun pits, underground ammunition rooms, and a restored fire control station. The site is less developed than Battery Spencer, offering a more authentic, rugged experience.
The trail between the two batteries is approximately 0.4 miles and includes moderate elevation gain. It passes through native grasslands and offers secluded views of the bridge’s northern tower and the Pacific coastline.
Step 5: Return or Extend Your Hike
You have several options for returning:
- Back the way you came – The most straightforward option. The descent is easier than the ascent but still requires caution on loose gravel.
- Connect to the Coastal Trail – From Battery Spencer, follow the paved path eastward toward the Golden Gate Bridge Toll Plaza. From there, you can access the Golden Gate Bridge Trail and walk back to Crissy Field or the Presidio.
- Loop via the Headlands – For experienced hikers, continue north along the Marin Headlands Coastal Trail to Rodeo Beach, then take the Rodeo Valley Trail back to the Presidio. This adds 5–7 miles to your hike but rewards you with coastal bluffs, tide pools, and wildlife.
Plan your return based on your fitness level, time available, and weather conditions. Wind can be strong at the top—dress in layers.
Best Practices
Hiking to the coastal batteries near the Golden Gate Bridge is a rewarding experience, but it requires preparation. Follow these best practices to ensure safety, respect for the environment, and maximum enjoyment.
1. Time Your Hike Wisely
The best times to hike are early morning (6–9 a.m.) or late afternoon (3–6 p.m.). Midday sun can be intense, and the trail offers little shade. Fog is common in San Francisco, especially between June and August. While fog can obscure views, it also creates dramatic, moody photography opportunities. Check the National Weather Service forecast for the Presidio and Golden Gate Bridge before heading out.
2. Dress for Variable Conditions
Temperatures at the top of Battery Spencer can be 10–15°F cooler than at sea level, even on sunny days. Wear moisture-wicking base layers, a windproof jacket, and a hat. Gloves are helpful for gripping railings on steep sections. Avoid cotton—it retains moisture and can lead to chills.
3. Pack Essentials
Even on short hikes, carry:
- At least 16 oz of water per person
- Snacks (energy bars, nuts, fruit)
- First-aid kit (bandages, antiseptic wipes)
- Map or offline GPS (cell service is spotty)
- Phone with fully charged battery
- Camera or smartphone for photos
There are no vending machines or restrooms at Battery Spencer or Battery Godfrey. Use facilities at the Welcome Center or Crissy Field before you begin.
4. Stay on Designated Trails
The GGNRA is a protected area. Straying from marked paths damages fragile native vegetation and disturbs nesting birds. Stay on the trail, even if shortcuts seem tempting. Respect all signage—some areas are closed for archaeological preservation or wildlife protection.
5. Respect Historical Sites
Battery Spencer and Battery Godfrey are part of U.S. military history. Do not climb on gun emplacements, remove artifacts, or graffiti. These structures are preserved for education and public appreciation. Take photos, but leave everything as you found it.
6. Be Aware of Wildlife
The area is home to coyotes, foxes, hawks, and the endangered San Francisco garter snake. Observe from a distance. Do not feed animals. If you encounter a coyote, make noise, wave your arms, and back away slowly. Do not turn your back.
7. Avoid Crowds on Weekends
Weekend afternoons, especially during holidays, bring large crowds to Battery Spencer. For a quieter experience, hike on weekdays or arrive before 8 a.m. The trail to Battery Godfrey is far less crowded and offers solitude if you’re seeking it.

Real Examples
Understanding how others have successfully completed this hike can provide valuable context. Below are three real-life examples of hikers who reached Battery Spencer and Battery Godfrey, each with different goals and backgrounds.
Example 1: The First-Time Visitor – Maria, 32, from Chicago
Maria visited San Francisco for a weekend trip and wanted to see the Golden Gate Bridge from the best possible vantage point. She arrived at the Welcome Center at 7:30 a.m. on a Tuesday, parked in the lot ($10), and followed the trail to Battery Spencer. She spent 45 minutes at the top taking photos and reading the interpretive signs. She then descended and walked back to Crissy Field, where she had coffee and watched the fog roll in. “I didn’t know batteries were part of the bridge’s history,” she said. “It felt like stepping into a movie set—except it was real.”
Example 2: The History Enthusiast – James, 58, Retired Military
James served in the U.S. Army for 28 years and has a personal interest in coastal defense systems. He hiked to Battery Godfrey with his grandson, who is 10 years old. He brought a printed copy of the 1943 Army Corps of Engineers manual on 155mm gun emplacements and explained how the guns were aimed using the fire control station. “Seeing the same concrete structures my father described in his letters—it’s emotional,” James said. “The preservation here is remarkable.”
Example 3: The Fitness Enthusiast – Dev, 29, Trail Runner
Dev trains for ultramarathons and uses the Battery Spencer trail as a speed workout. He timed himself: 12 minutes 45 seconds from the Welcome Center to the top of Battery Spencer. He then continued to Battery Godfrey and looped back via the Coastal Trail, completing a 7.2-mile circuit in under 90 minutes. “It’s the steepest 0.6 miles I’ve ever run,” he said. “But the view is the best reward in the city.”
Example 4: The Family Outing – The Chen Family, 4 Adults, 2 Children
The Chens brought their two young children (ages 6 and 8) on a Saturday morning. They started at Crissy Field, walked the flat path to the bridge, then took the Battery Spencer trail. They brought snacks, a stroller (which they left at the base), and a portable speaker playing nature sounds. “The kids loved spotting the birds and pretending the guns were lasers,” said Ms. Chen. “We didn’t make it to Battery Godfrey, but we didn’t need to. The view was enough.”
These examples illustrate the diversity of experiences possible on this hike. Whether you’re seeking solitude, education, exercise, or family time, the batteries offer something meaningful.
