The Man and the Money

Adolph Sutro arrived in San Francisco in 1850 as a twenty-year-old German-Jewish immigrant and left it, four decades later, as the city's twenty-fourth mayor. The fortune in between came from a tunnel. The Comstock Lode, a vast vein of silver and gold under Nevada's Virginia City, was flooding faster than its mines could pump it dry. Sutro proposed a drainage adit — a horizontal shaft four miles long, twenty feet wide, more than a hundred feet deeper than any mine — and the skeptics in the room said it could not be done. After years of argument and partial collapse and political warfare in Washington, the Sutro Tunnel opened in 1878 and ran for decades, venting the mines and draining the ore. He sold his interests and came home to the coast with more money than he had any obvious use for. So he bought land. He bought so much of the western slope of San Francisco, the contemporary press stopped counting acres and started counting neighborhoods. Look toward the Cliff House to see the headlands he owned.

On the ground

Checked against official sources on the dates shown. Nothing here is a price or an opening hour — those go stale.

Which way in

  • Merrie Way lot, then the stairs

    The ruins sit directly below the Lands End trailhead lot. Take the stairs down from the parking area.

    checked 2026-09-07
  • Geary Boulevard, all the way west

    Driving, stay on Geary until it runs out and you are at the ruins. The site is where Geary and the Great Highway converge at the north end of Ocean Beach.

    checked 2026-09-07
  • The 38 bus

    The 38 runs closest. The 5, 18 and 31 also get you within reach.

When to come

  • A weekday

    The ruins get fairly crowded at weekends.

    checked 2026-09-07
  • Sunset

    The best time is argued over, but most people land on the light at sunset.

    checked 2026-09-07
  • Around a tide change

    The ruins sit at water level, and the place reads differently as the tide rolls in and out.

    checked 2026-09-07
  • September or early October

    The most reliably clear months. July is statistically the foggiest.

    checked 2026-09-07

When not to

  • Turning your back on the water among the pool walls

    Sneaker waves sweep across the beach without warning and take people off rocks into the sea.

    checked 2026-09-07
  • Treating this as a swimming or beachcombing shore

    Rough surf, rip currents and cold water make the coastal beaches here unsafe for both.

    checked 2026-09-07
  • The slope down to the cave, in poor footwear

    It is a steep, uneven gravel descent and people stumble on it.

    checked 2026-09-07
  • Leaving the trails on the cliffs

    The fire department has warned hikers off the cliffs here after three rescues in a fortnight.

    checked 2026-09-07

Where the shot is

  • The sea cave at the far end of the ruins

    A quarry tunnel from the late 1880s, about ten feet wide and a hundred and fifty-two feet long, with the open Pacific framed at its mouth.

    checked 2026-09-07
  • Between the rocks at the far mouth of the tunnel

    Pieces of the original mine-cart track, still there.

"The walk down the ruins is short but has 141 steps, so you get a little workout."

Tip: If you have knee or mobility concerns, treat the 141 steps as a real descent and ascent and plan a slower return.

Frequently asked

What were the Sutro Baths?
The largest indoor swimming establishment in the world when it opened in 1896: seven pools at different temperatures under a glass and iron roof at the edge of the Pacific, with a museum, an amphitheatre and a concert hall attached. It could hold 10,000 people at a time and rented out 20,000 bathing suits and 40,000 towels.
How did the Sutro Baths burn down?
A fire in June 1966 destroyed the building down to its concrete foundation while demolition crews were already at work on the closed site. Investigators determined the cause was arson. The glass roof came down overnight and the iron frame was left standing bare.
Can you visit the Sutro Baths ruins?
Yes. The site is part of the Golden Gate National Recreation Area, open and free, with no ticket and no gate. You can walk down into the foundation and stand where the pools were. The concrete is uneven and slick where the tide reaches it, so flat shoes matter more than they sound like they should.
Who was Adolph Sutro?
A mining engineer who made a fortune engineering a drainage tunnel for the Comstock Lode, then bought a large share of San Francisco and served as its mayor from 1895 to 1897. He built the baths on the principle that working people should have access to what the wealthy took for granted.
How big were the Sutro Baths?
The glass house measured 499.5 feet by 254.1 feet and covered about three acres. Filling it took on the order of two million gallons of seawater, drawn in at high tide, which turned the whole volume over in about an hour. The pumps took five.
