Family Adventure in the Marin Headlands

Located at the very south end of Marin County, the Marin Headlands has much to offer for families and is one of our favorite destinations for a day of outdoor adventure. The Marine Mammal Center, wildlife, beaches, history, natural beauty, sweeping vistas of the Pacific and San Francisco — the Headlands has all that and more.

Now part of the Golden Gate National Recreation Area, the Marin Headlands was at one time home to a Spanish and Mexican rancho, military fortifications, and Cold-War-era Nike missile sites. It also narrowly escaped becoming a massive housing development called Marincello back in the 1960s. Thankfully that never came to pass, and we're left with a superlative national park enjoyed by countless Bay Area residents and visitors.

One of our must-visit Marin Headlands destination is Rodeo Beach. This dark-sand beach, accessible via a footbridge across Rodeo Lagoon, is a popular spot for surfing, bird-watching, kite flying, picnicking, surfing, dog walking, and just relaxing oceanside on a warm day.

The sand here is composed of tiny little pebbles of colorful stone, and children always have a great time picking through it for particularly colorful specimens, including jade, black agate, jasper, and carnelian. Like most beaches along Marin's coast, Rodeo Beach isn't safe for swimming, surfers notwithstanding.

Located nearby in Fort Cronhkite, the Marine Mammal Center is another Marin Headlands must-see. You can take a free self-guided tour and see seals and sea lions that the center is nursing back to health and learn more about our local pinnipeds. Admission to the Marine Mammal Center is free, but tickets must be reserved in advance. Read more about the Marine Mammal Center. 

Hiking trails abound throughout the headlands. One of our favorite kid-friendly hikes is to head up the hill on the Coastal Trail from Rodeo Beach. The trail winds up on the bluffs overlooking Rodeo Beach and Fort Cronkhite and offers some spectacular views. We also love to hike down to South Rodeo Beach, which is always less crowded but no less spectacular than its more popular sibling. Other worthwhile hikes nearby are on the Lagoon Trail and the Rodeo Valley Trail.

The other big draw at the Marin Headlands is history. Throughout the 20th century, the Headlands was the site of the US Army's Forts Barry and Cronkhite, as the countless leftover military buildings and fortifications attest. Kids love to clamber around the old concrete gun batteries that line the coastal bluffs here.

One of our favorite places to explore is Battery Mendell, at the end of Fort Barry Road near the Point Bonita YMCA. Built in 1902, Battery Mendell is sited high on a hill overlooking Rodeo Beach and the Pacific, and was once home to two 12-inch disappearing rifles — coastal artillery pieces that would hide themselves after each shot to avoid enemy detection.

Battery Alexander — once home to heavy mortars and now to picnic areas — is worth visiting, as is the later Battery Wallace, which looks like it's literally buit into the hillside. Keep in mind that while these historic structures are fun to visit and play on, they are constructed of materials like concrete and iron and weren't built with safety in mind, so exercise caution.

You can also visit a restored Cold-War-era Nike missile site, SF-88L, one of many that once dotted hills around Marin County and the San Francisco Bay Area. The Nike missile was an anti-aircraft weapon that deployed a nuclear warhead, and was meant to be the last line of defense again attacking Soviet bombers in the 1950s and '60s.

The Marin Headlands Nike Missile Site is currently open on Thursdays, Fridays, and Saturdays from noon to 3 pm. You can take a guided tour of the facility, the only restored Nike missile site in the country, and learn about its history from rangers and volunteers. On guided tours you can see everything up close and even watch as an (deactivated, thankfully!) Nike Hercules missile is lifted up into firing position from its underground storage area.

Tours are offered periodically during opening hours, and there's a Veteran Open House Day on the first Saturday of every month, where Nike veterans share their stories with visitors.

Another important historic structure you can visit at the Marin Headlands is Point Bonita Lighthouse. Built back in the 1850s to guide mariners away from the rocky shores of the Golden Gate, the lighthouse is accessed by walking down a winding trail and then across a recently rebuilt suspension bridge. (Point Bonita is the only lighthouse in America that's accessed via suspension bridge.)

It's an easy, fun, hike for the family, with amazing views, and is open Friday through Monday from 12:30 to 3:30 pm; starting May 2024, the lighthouse will be open on Friday through Sunday from 10:30 am to 3:30 pm and Mondays and Thursdays from 12:30 to 3:30 pm. The last entry is at 3:20 pm.

If You Go

To get to the Marin Headlands, take Highway 101 south to the Alexander Avenue exit. Go right at the stop sign and follow Alexander Avenue back under the freeway. Turn left on Danes Drive and take the famous, one-way, mile-long tunnel to Bunker Road. The tunnel is one-way, so you may have to wait for up to five minutes for oncoming traffic to come through. Follow Bunker Road into the headlands—it will lead all the way to Rodeo Beach and Fort Cronkhite.

You could also head the opposite direction at the Alexander Avenue exit and head up Conzelman Road into the Headlands, but the Bunker Road Tunnel is an important part of the experience, and a big hit with kids.

The Marin Headlands visitor center is open daily from 9:30 am to 4:30 pm (closed on Tuesdays as well as Thanksgiving, Christmas Day, and New Year's Day), and the park itself is open sunrise to sunset. Restrooms are available at the visitor center and at Rodeo Beach, and there are portable toilets located throughout the park. Plenty of picnic tables and BBQ grills can be found here, but bring your own food in as there's no place to get it at the park.

Northern California coastal weather can be unpredictable, so be prepared for anything from blazing sunshine to howling winds and fog. Dress in layers, and bring hats and sunscreen. Wear sturdy shoes for hiking and exploring old bunkers. Keep in mind that early 20th-century military fortifications weren't exactly designed with safety in mind, so keep an eye on little ones at all times.

It can get busy in the Marin Headlands on weekends and holidays, especially during the summer tourist season. If you go during the week, you'll find you pretty much have the place to yourself.
