This sheltered respite, just a stone's throw from Union Street shopping, is almost always warm even on the windiest San Francisco day. Ideal for babies to preschool-aged children, this fenced, sand-surfaced mini-park just isn't large enough to please older children. A Tiny Tots program is available Tue,Wed,Fri from 10:30am-12:30pm for 2.5- to 5-year olds and Mon from 10:30am-11:30am for 1- to 2-year olds. Parties: A nice place to throw a party for little kids. The clubhouse can be rented.
