Seven Seas Park is in Sunnyvale and has one of the best water park splash pads in the Bay Area! This park is located at 1010 Morse Ave, Sunnyvale, CA 94089. Seven Seas is well shaded with sunshades. There’s a separate playground area for babies, and a big pirate ship for bigger kids. There are musical structures throughout the large playing field. There is a basketball and tennis court. Most importantly with young kids, there are bathrooms here! There is also a nice large dog park pictured above. My boys and I rate this as our top favorite park this summer.
