Marin Headlands: Guardians of the Golden Gate

Long before the bridge or its paint, an army officer looked through this strait and reached for a Greek name borrowed from a famous harbor across the world. The gold that would make the label fit hadn't been found yet…

A signed shoulder on the lower two-way grade where the span opens out beneath you. Here you gain enough height to look straight down the bridge's length instead of up at it from the shoreline, and you can see how a si…

For drivers heading south on US-101 toward the Golden Gate Bridge from Marin/Sonoma. Turn-by-turn onto Conzelman Road — Exit 442 Alexander Ave before the bridge, left at the stop, immediate right up Conzelman — plus t…

Now hold up a second, friend, and put your hand flat against one of these roadcuts. Feel that? Cold stone, quiet as anything. But this rock is a traveler, and it has come a mighty long way to sit here under your palm.…

The rusty banded rock exposed where Conzelman Road cuts the ridge is radiolarian ribbon chert, built grain by grain from deep-Pacific plankton shells. It traveled north on an ocean plate and was scraped onto Marin as…

Boone's take on how the Golden Gate came by its warm hue. Consulting architect Irving Morrow noticed the reddish primer on the arriving steel and pushed to keep a warm color so the span would read against water, sky,…

For drivers crossing the Golden Gate Bridge northbound from San Francisco. Turn-by-turn onto Conzelman Road — pass Vista Point, take the Alexander Ave exit, left under the freeway, right up Conzelman — plus who Quinn…

Everyone knows the Golden Gate as Joseph Strauss's bridge, but he shared the credit. Strauss was the chief engineer and tireless champion, while engineer Charles Ellis ran the structural calculations that let the span…

A short, flat stroll from a cramped roadside pullout out to weathered concrete gun pits from the 1890s, staring straight down at the Golden Gate Bridge's north tower. The old artillery is long gone; what remains is a…

A high perch on Conzelman Road where autumn sends the largest known gathering of migrating birds of prey along the Pacific Coast streaming over the strait. It's also the final two-way pullout before the pavement drops…

Fort Barry's Field Road loop is the orientation pause on the valley floor, anchored by a former army chapel that now houses the Marin Headlands Visitor Center. Stop in to confirm which limited-hours attractions are ru…

Behind an unassuming gate off Field Road stands SF-88, kept much as it looked when crews here watched the skies for Soviet bombers. The exhibit follows the leap from the conventional Ajax to the nuclear-tipped Hercule…

One foggy February night in 1901, the inbound steamer City of Rio de Janeiro missed the Gate, tore open on the rocks by Fort Point, and went down in about ten minutes with scores of sleeping emigrant passengers. Boone…

Before any foghorn, the Army met Point Bonita's blinding gray with a booming surplus siege gun — said to be the West Coast's earliest fog signal. Boone tells of the thunder rolling through the murk and the worn-down s…

Boone's stop at Point Bonita: the human story of a light reached only through a hand-cut rock tunnel out to a wind-lashed point, where keepers minded the wick and fog signal until the Coast Guard automated the station…

Earn Point Bonita on foot: a half-mile trail threads a hand-cut rock tunnel out to a low light moved down near the water to slip beneath the summit fog. Its historic Fresnel lens still turns. The suspension footbridge…

A cautious ocean pause on Mendell Road above the south end of Rodeo Beach, looking down on the rocky hump of Bird Island. Scan the offshore rocks for hauled-out harbor seals any month of the year, keep an eye out for…

Passing Rodeo Lagoon, where a pebble bar thrown up by the surf traps a salt-and-fresh wetland alive with herons, ducks, the occasional otter, and the federally threatened red-legged frog. All wildlife framed as season…

Where the valley road dead-ends behind the lagoon: a beach that crunches underfoot, paved in surf-polished Franciscan pebbles — reds, greens, and honey tones of jasper, carnelian, and agate you can admire but never po…

Trailhead intro: why the half-mile climb to Battery Townsley is worth it — the most secret WWII fort at the Golden Gate and its giant 16-inch guns.

Boone on Battery Townsley: the secret WWII fort, its two 16-inch battleship guns, the 150 soldiers, and guns that never fired a shot in anger.

Park at Rodeo Beach and hike up the Coastal Trail to a hulking WWII casemate that once housed two sixteen-inch guns. Walk the concrete exterior above the Pacific, hear why these battleship-scale weapons never fired a…

Behind Fort Cronkhite's old Nike launch pads sits a hospital for seals and sea lions, one the Center itself calls the world's largest of its kind. Staff rehabilitate ocean mammals stranded along hundreds of miles of C…

In the 1960s Gerbode Valley was slated to become Marincello, a Gulf Oil-financed city of ridgetop high-rises, a mile-long mall, and a hilltop hotel that won county approval in 1965. Ceremonial gates and a wide bouleva…

A quiet drive-by glance north into roadless Gerbode Valley, where a mid-century planned town called Marincello nearly rose before the ground became parkland instead. Quinn traces how an approved city unraveled and the…

Standing above Rodeo Lagoon, Boone reframes these headlands as Coast Miwok homeland — and insists on the present tense. The Coast Miwok live on today as citizens of the federally recognized Federated Indians of Graton…

The last leg out of the Headlands runs through a narrow single-lane bore on Bunker Road, where signals at each end take turns letting one direction through at a time. Named for the two forts it connects, Baker and Bar…
