Larkey Park, right next to the Lindsay Wildlife Museum, has big grassy fields and tall trees providing plenty of shade, with picnic tables, restrooms, and a playground. The Briones to Mount Diablo Trail runs right through the park with connections to the Acalanes Ridge and the backside of Briones Regional Park, along with a few other local walking trails that connect here, making it a great base to park and satellite out to explore the surrounding areas.
