Cool off & play the day away at our drop-in activity, no registration required! Join the San Bernardino County Regional Parks’ Team for a fun-filled day at the splash pad, complete with exciting games, refreshing snow cones, and a hands-on environmental science adventure! We’ll kick off the day with an engaging oil spill simulation, where kids get to step into the role of conservationists, working together to clean up a pretend ocean disaster. This interactive activity will teach valuable lessons about protecting our waterways and the impact of pollution on marine life. Then, dive into the fun with splashing water play, classic lawn games, and icy treats to beat the heat! Whether you’re racing through sprinklers, tossing bean bags, or just relaxing in the sun, it’s the perfect way to enjoy summer while learning about nature. Don’t miss out on the ultimate family fun day—grab your swimsuits, towels, and game face, and we’ll see you there!
