Until Potrero Del Sol came along, this was San Francisco's only skatepark. It's a tiny park with a square bowl and a couple ledges. This is located in Crocker-Amazon park on the outskirts of San Francisco. From SF take 101 South and take a right a the Geneva exit. Go about a mile and you'll see Crocker-Amazon playground on the right. Or just save yourself the trouble and go to Potrero Del Sol in the Mission.
