Two windsurfers at Brannan Island SRAThe park, approximately 336 acres in size, is accessed by Highway 160 a few miles south of the city of Rio Vista in Sacramento County. The park is located on the lower peninsular extension of Brannan Island, and is surrounded by the Sacramento River on the west, Three Mile Slough on the southeast, and Seven Mile Slough on the northeast. The park has a 6 lane launch ramp, over 140 campsites and areas for picnicking and swimming. A small visitor center just inside the entrance is open on weekends. The park is a high use recreation area which receives heavy use from May through October. The late fall, winter and early spring months are much slower paced at the park and offer some of the best fishing opportunities of the year. The climate in the Delta is mild, with winter temperatures usually ranging between 45 and 55 degrees and summer temperatures between 75 and 95. An occasional heat wave will push the temperatures in summer to 100 degrees or more but the Delta breeze is never far away.
