The Parks Forward Commission has collaborated with others to create a new app, caliparks.org, that allows you to find parks, trails and other recreation opportunities near you within California.
When I clicked through to State Parks and typed Walnut Grove, CA into the search bar, 4 nearby parks came up:
- Stone Lakes
- Stone Lakes Wildlife Refuge
- Franks Tract State Recreation Area
- Brannan Island State Recreation Area.
In addition the application allows you to locate camping sites, mountain bike trails, dog walking opportunities, and beaches.
