Its newer playground is the big draw for kids: a 30-foot-high play structure with an enclosed slide, bridges, swings and a cargo-net climbing course, a toddler area for sand play, climbing, sliding, swinging and making music, and a rock-formation splash pad with jets, waterfalls and sprinklers that runs April 1 to October 1. Families can also fish year-round at Cottonwood Lake, picnic at first-come family sites, and watch riders on the park's Olympic-size open-air banked velodrome. Kids with a phone or tablet can also play Agents of Discovery, a free 30–45 minute educational mission game on the paved paths that starts near the playground. ## Similar picks in San Jose - [Magical Bridge Playground at Central Park — Santa Clara](https://grassyknees.com/san-jose/activities/magical-bridge-playground-at-central-park-santa-clara--listing-34a65dd43489ac15b72ef945) — Free and open every day, dawn to dusk. · Magical Bridge Playground, Central Park, Santa Clara · All ages · Free · checked Oct 24.
