Camping—San Luis Creek sites have water and power hookups. Reservations are recommended for developed family or group campsites at Basalt and San Luis Creek campgrounds on warmer weekends and holidays.

Picnicking—The San Luis Creek dayuse area offers shaded picnic tables near sandy beaches. The OHV area also has picnic tables. Call (209) 826-1197 in advance to reserve group picnic areas.

Swimming—San Luis Creek’s North Beach area is the only roped area designated for swimming. Swimmers throughout the park should be cautious of boats on the water. No lifeguards are on duty. Scuba and other kinds of diving are not allowed.

Boating—All boats entering the park are inspected for invasive species. All watercraft must carry an appropriate size personal flotation device (PFD) for each passenger. Boats must remain at least 500 feet away from the dams and water structures. Watch for wind-warning lights and observe speed limits.

San Luis Reservoir—Wind-warning lights are located at the Romero Visitor Center, Quien Sabe Point, and the Basalt entrance. See map for details.

-O’Neill Forebay—Watch wind-warning lights at the southeast area of Medeiros, above the South Beach picnic area, and above the San Luis Creek group camp. Boaters may beach their boats at South Beach. O’Neill Forebay’s winds make it excellent for board sailing.

Trails—The five-mile San Luis Creek Accessible Trail runs along the O’Neill Forebay shoreline. The Basalt Campground Trail begins west of the campground road. The six-mile-round-trip Lone Oak Trail begins near the Basalt boat ramp.

Fishing—All anglers 16 and over must carry a valid California fishing license.

- San Luis Reservoir/O’Neill Forebay— Largemouth black bass, striped bass, crappie, shad, perch, and occasionally salmon and sturgeon are caught here. Overnight fishing is permitted in some parts of the San Luis Creek area. At Medeiros, only registered campers may fish after sunset.

- Los Baños Creek Reservoir—Crappie, bluegill, largemouth bass, catfish, and trout may be caught here.

Hunting—Federal and state game laws apply to in-season waterfowl hunting—including licenses. Only shotguns are allowed. Hunting is not permitted within 500 feet of campgrounds, picnic areas, boat ramp areas, or dam and water structures.
