Discovery Bay Marina & RV Park has full-service RV hookups and pull-through sites with direct marina access, making it a prime choice for a toy hauler. Brannan Island State Recreation Area features RV-friendly campsites, boat ramps, and scenic Delta views that accommodate longer stays and equipment storage. Big Break Regional Shoreline is a scenic park with day-use parking and shoreline access when you prefer a waterfront picnic without an overnight setup. All three locations give easy access from State Route 4 and offer the space and amenities to park, unhitch, and launch toys from a secure base in Discovery Bay.
