I know it reopened in February, but we just finally took the kids by Hal Brown Park (formerly Creekside Park), across from Marin General, and the renovation is impressive. It has great play structures, a large grassy area for playing soccer, an awesome loop for kids to ride their bikes around, and really sweet views of the lagoon and Mt. Tam. Great spot to picnic or have a kids birthday party. If you haven’t made it by it’s worth checking out while the weather is still nice.
