Have you visited the Prehistoric Playground in Laguna Hills yet? It has toddler/big-kid swings, dinosaur skeletons, diggers, super large jungle gym, bridges, water play and more! It's well maintained and perfect for all ages!
A replica of fossil reef has been recreated by the playground bridge and has imprints of actual fossils that are over 15 million years old. Under the bridge, a 70 million year old fossil replica of a Hadrosaur is imbedded into the bridge wall, along with fossil pieces of a saber toothed cat, duck-billed dinosaur and mammoths.
The prehistoric playground contains fossils - real and replicas - that represent a rich diversity of ancient life from the changing Laguna Hills environments. To walk across the playground is to walk through time. By enjoying the many paleontological features located throughout the playground, visitors can discover the ancient life that walked, swam, and flew thousands of years ago in the Saddleback Valley. While you are there also check inside the Laguna Hills Community Center to see their extensive fossil display.
FYI - this park appears as "Dinosaur Park" in Google Maps.
