Brannan Island State Recreation Area is a popular spot near Discovery Bay with RV sites that offer electrical hookups, boat launches and direct access to the delta waterways. Camanche State Recreation Area is another option within reasonable driving distance, with full hookups and campsites that can accommodate larger rigs, plus boat ramps and shoreline fishing. Both campgrounds are serviced by nearby towns where you can find fuel and basic supplies, so planning for propane and diesel is straightforward. Reservations are recommended during summer and holiday weekends to secure pull-through or larger sites.
