Free things to do with kids in Sunnyvale

Sunnyvale's nautical-themed neighborhood park: a ship-play structure little captains climb all over, plus open lawn and picnic spots in north Sunnyvale.

A Victorian-themed park with a big playground plus a separate fenced-feeling tot lot, picnic sites with power outlets, tennis, and permanent restrooms. The gazebo and lawns make it a birthday-party staple.

Sunnyvale's Magical Bridge: wheelchair users and runners share the same swings, carousel, laser harp, and water play - inclusive design as the starting point, not an add-on. A two-story structure and sensory hideaways make it a South Bay essential.

70 acres of developed parkland at the edge of the bay: playground, big picnic grounds, permanent restrooms, and a gateway to the Bay Trail levees where planes float into Moffett. $6 parking March through October; free in winter.

Recently rebuilt neighborhood park with a modern playground, a separate tot lot for under-5s, sports fields, and permanent restrooms. A solid everyday park rather than a destination - clean, new, and rarely mobbed.
