Cottonwood Campground at Brannan Island State Recreation Area offers 102 spacious campsites with direct access to the Sacramento River and surrounding sloughs, featuring a 10-lane boat launch ramp for boating and excellent fishing opportunities.

The campground provides amenities including flush toilets, showers, potable water, and a 3-mile paved loop trail, with sites accommodating RVs up to 36 feet; however, note that sites lack utility hookups and strong winds (25+ mph) are common, requiring secure tent setup.

Reservations are recommended 2-3 months in advance during peak season (May-October), with winter offering quieter conditions ideal for fishing.
