Gloomy San Francisco Days are always good for exploring ruins. This week, on a particularly grey and windy day, a friend and I took a stroll through the Sutro Baths in San Francisco…or at least what’s left of them. If I were making a low-budge, post-apocalyptic student film, I would probably use the site as my primary location. It’s been 40 years since the baths burned down, but what remains still has a definite ground-zero vibe. Mysterious pieces of concrete and brick walls jut out of the hillside growth and unusual sand formations. Navigating the site can be tricky—as Maude will surely attest—with pieces of bent, rusted metal and concrete holes aiming to trip up careless explorers. When the Sutro Baths opened in 1896, it was the world’s largest indoor swimming hole — complete with 7 different pools, a private museum and 8,000 seat concert hall.
