Seward Street Slides
The Verdict
"Bring your own cardboard or grab a piece from the box at the top. The slides are faster than they look. At Seward and Douglass in the Castro, near the intersection with Corwin. Free and open during daylight."
What you need to know
A Concrete Thrill Ride in a Neighborhood Park
Two concrete slides sit at the bottom of a steep staircase in Seward Mini Park, tucked into a residential block in the Castro. They were built in the 1970s as a neighborhood amenity. Somehow, they became one of the most fun free things to do in San Francisco.
The slides are fast. Steeper than they look. You sit on a piece of cardboard (usually available in a pile at the bottom) and let gravity do the rest. Kids love them. Adults love them more than they expect to.
What Makes It Worth It
This is pure, stupid fun. No tickets, no line (usually), no app. Just two slick concrete chutes and a piece of cardboard between you and a very quick ride.
The park itself is tiny: a basketball court, a small playground, and the slides. The views of the Castro rooftops and downtown are a nice bonus. It’s the kind of place locals bring visitors when they want to show them something that isn’t on any official tour.
Skip this if you have mobility issues. The stairs are steep and there’s no accessible path to the slides. Also not great in wet weather; the concrete gets slippery and the slides close when it rains.
Visiting
