Concrete Slide

If you’ve never slid down a massive concrete slide on a piece of cardboard, Codornices Park is where you fix that. This Berkeley landmark has been thrilling kids and fully grown adults for decades — bring your own cardboard or scavenge some from the pile locals leave behind. The slide is steep enough to feel genuinely fast, and watching first-timers figure that out is half the entertainment. Beyond the slide, there are trails threading into the hills, shade trees, and enough open space to make an afternoon of it. Honestly, it’s one of those spots that locals take for granted until they bring someone from out of town and remember how good it actually is.
