01
Best overall pick
Sandy Beach County Park & Campground
Just South Of Rio Vista Along The Sacramento River • Relaxed Riverfront Campground Beach • Easygoing All-Day Hangout
A classic sandy river beach with camping, shade, and gentle water a few minutes from downtown Rio Vista.
Sandy Beach is the go-to spot when you want a real stretch of sand without leaving town. The beach slopes gradually into the Sacramento River, making it comfortable for wading and cooling off on hot afternoons. Picnic tables, nearby restrooms, and the option to stay overnight at the adjacent campground make it an easy base for a full weekend by the water.
02
Delta adventure hub
Brannan Island State Recreation Area
Across The Rio Vista Bridge Toward Isleton • State Park Swim And Boat Beach • Best For Active Days On The Water
A maze of Delta channels with small swim beaches, launch ramps, and breezy shoreline perfect for mixing paddling and lounging.
Just over the bridge from Rio Vista, Brannan Island offers that classic Delta feel, with low sandy edges, tule reeds, and boats sliding by on the nearby sloughs. Small, designated swim areas give you a place to splash around, while ramps and docks make it simple to put in a kayak or fishing boat. It is a solid choice when your group wants both beach time and time exploring the waterways.
03
Wind lover's beach
Sherman Island County Park
Sherman Island, West Of Rio Vista • Windy Water-Sports Beach • Best For Kitesurfers And Windsurfers
A breezy stretch of Delta shoreline known for steady winds, kite lines in the sky, and sandy patches exposed at lower tides.
Sherman Island is where you go when the wind is up and you want more action than sunbathing. Launch spots along the levee attract a tight-knit crew of kitesurfers and windsurfers, with plenty of room to rig gear and watch the show from shore. On calmer days and lower tides, the small sandy pockets along the edge make for a quiet, open-feeling place to sit by the water and watch the shipping channel traffic roll past.
04
Most convenient in-town spot
Bruning Park Riverfront Beach
Downtown Rio Vista Waterfront • In-Town Picnic And Paddle Beach • Best For Quick Local Escapes
A small riverfront park with marina views, pockets of sand, and easy access for a quick dip or paddle near Main Street.
Bruning Park sits right on the Rio Vista waterfront, so you can grab a coffee or lunch in town and be at the river in minutes. The shoreline here has a mix of grassy picnic space, docks, and little sandy edges where kids can poke around in the shallows. It is not a big sprawling beach, but it is ideal when you want a low-effort hour by the water without driving out to the countryside.
05
Wildest waterside escape
Grizzly Island Wildlife Area Shoreline
South-Central Suisun Marsh, East Of Fairfield • Remote Marsh-Side Shoreline • Best For Quiet Nature Time By The Water
A rugged mix of levee roads and muddy shoreline that trades classic sand for big skies, wildlife, and open-water views.
Grizzly Island is less about towels and umbrellas and more about feeling tucked into the heart of the Delta marsh. From pullouts along the levees, you can wander short distances to the water's edge, watch waterfowl and raptors, and take in broad views of sloughs and open bays. It is the pick when you want a quieter, more wild version of a beach day and do not mind a softer, marshy shoreline underfoot.
