This park northeast of San Francisco Bay has countless islands and marshes with many wildlife habitats and many opportunities for recreation, including boating, windsurfing and swimming. The 329-acre (133 ha) park was established in 1952.The area offers fishing, including striped bass, sturgeon, catfish, bluegill, perch and bullhead. Southeast, accessed by the San Joaquin River, Frank’s Tract, a protected wetland marsh, is home to beaver, muskrat, river otter, mink and 76 species of birds. Another wetland also managed by Brannan Island's Park Rangers is Delta Meadows River Park near the town of Locke. Canoe tours of 'the meadows' may be reserved on weekends during the spring and fall season through Brannan Island SRA.Brannan Island SRA has a six-lane launch ramp, over 140 campsites and areas for picnicking and swimming. The visitor center is open weekends and by arrangement. Inside are displays on the cultural and natural history of the Delta, including a large interactive map of the San Francisco Bay Area and Delta. Day use areas include the Windy Cove windsurfing access, the group picnic area located at the Ramadas, and Seven Mile Slough picnic area. The group picnic facility and Seven Mile Slough day use area close at sunset. Windy Cove closes at the hour posted at the entrance road to Windy Cove. Seven Mile Slough picnic area includes picnic tables, barbecues and drinking water. New restroom facilities were completed late in 1997 and include flush toilets and outdoor cold showers. Seven Mile Slough's swim beach has lifeguards from Memorial Day through Labor Day. Ample parking is close to the beach. The Ramadas have shaded picnic structures with large barbecues, picnic tables, water and trash receptacles. A large open grassy area is adjacent to the site for games. The closest restroom to the Ramadas is located north of the swim beach along Seven Mile Slough. 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. The park was closed starting April 1, 2022, while California State Parks sought a new operator. The park was partially reopened from June to September, 2022, and fully reopened December 1, 2022, operated by Park Delta Bay, a nearby resort.

Decker Island is a small island in the Sacramento-San Joaquin River delta, in California. It is part of Solano County. Its coordinates are 38.0904745°N 121.7191214°W / 38.0904745; -121.7191214 (Decker Island).

Bradford Island is a 2,172-acre (879 ha) island of the Sacramento–San Joaquin River Delta, in Contra Costa County, California, United States. Bradford Island is inaccessible by roads, and is served by a ferry across the False River from nearby Jersey Island. Approximately 48 people lived on the island as of 2020; other uses of land include wheat farming, cattle grazing, and natural gas extraction. Bradford Island is a reclaimed peat wetland; as it lies below sea level, it is protected by flooding by levees. These, as well as a pump station and internal drainage canals, are administered by Reclamation District 2059, founded in 1921. The levees have been breached on several occasions, leading to the island becoming flooded. Bradford Island is one of eight Delta islands considered critical to the region's water quality by the California Department of Water Resources.

Sherman Island is an island in the Sacramento-San Joaquin River Delta at the confluence of the two rivers in Sacramento County, California, 1.2 miles (1.9 km) northeast of Antioch. The 5,500 ha (14,000 acres) island, mostly managed by Reclamation District 341, is the meeting point of Sacramento, Solano, and Contra Costa Counties, and is bordered on the north and northwest by the Sacramento River, on the northeast by Three Mile Slough, and on the east, and south west by the San Joaquin River. Sherman Island is a widely known kite and windsurfing area. Sherman Island was shown, in the same location but with a different shape, on an 1850 survey map of the San Francisco Bay area made by Cadwalader Ringgold and an 1854 map of the area by Henry Lange. Currently, it is 10 feet below sea level, due to the drainage of wetlands in the Delta which has dried out its peat soils, resulting in land subsidence. "In ... parts of Sherman Island, the land has now subsided 25 feet since the late 1800s—and continues to sink between half an inch and 1.5 inches yearly." It is possible that simultaneous levee failures on Sherman Island and surrounding islands, occurring in the wake of an earthquake, could threaten the fresh water supply for the Central Valley.

Jersey Island is an island in the Sacramento-San Joaquin River Delta of Contra Costa County, California, approximately 10 kilometres (6.2 mi) east of Antioch. The 1,425-hectare (3,520-acre) bounded on the west by the San Joaquin River-Stockton Deepwater Shipping Channel, on the north by the False River, on the northeast by Piper Slough, on the east by Taylor Slough, and on the south by Dutch Slough. It is administered by Reclamation District 830.

{{Merger with Franks Tract State Recreation Area has been proposed. Please see Talk page.}} The Antioch Bombing Target a 500-acre (200 ha) plot was a United States Navy target used from 1943 to 1952. It is now part of the Franks Tract State Recreation Area.

Franks Tract State Recreation Area (SRA) is a state park unit of California, United States, featuring a flooded area in the Sacramento–San Joaquin River Delta. It is accessible only by water. Franks Tract, and a smaller adjoining submerged property called "Little Franks Tract", are situated between the False River and Bethel Island. The recreation area is used primarily for fishing and waterfowl hunting, because of its exposure to frequent strong winds and fluctuating water levels. In times of high water, the entire site can be submerged except for portions of the old levees. The 3,523-acre (1,426 ha) park was established in 1959. It is managed from nearby Brannan Island State Recreation Area, 6 miles (9.7 km) to the northwest.

The Antioch Bridge (officially the Senator John A. Nejedly Bridge) is an automobile, bicycle, and pedestrian bridge in the western United States. Located in northern California, it crosses the San Joaquin River-Stockton Deepwater Shipping Channel, linking Antioch in Contra Costa County with Sherman Island in southern Sacramento County, near Rio Vista. Named after state senator John Nejedly, the bridge is signed as part of State Route 160. Unlike other toll bridges in California, it has only a single lane of traffic for each direction. It is one of several bridges in the Bay area that are traversable by pedestrians and bicyclists in addition to automobiles. The current bridge was completed 46 years ago in 1978, is 1.8 miles (2.9 km) in length, and opened to traffic that December.

Antioch/Oakley Regional Shoreline is a regional park that is part of the East Bay Regional Parks system. It is located on the south shore of the San Joaquin River in Contra Costa County, California, between the cities of Antioch and Oakley.

Antioch Bridge) was constructed across the river. The park was originally named Antioch Regional Shoreline, and was given its present name when Oakley incorporated as a city in 1999.
