The Twin Bridges Area at Grand Lake State Park is known for its quiet country atmosphere and excellent fishing for trophy-sized bass, catfish, bluegill and spoonbill. Bait and tackle are available at the gift shop. Lighted boat ramps, picnic areas, RV and tent campgrounds, snacks, lake huts, playgrounds, volleyball court and horseshoe pits are also available. Picnic facilities include tables, individual shelters and group picnic shelters for larger gatherings. Campsites range from RV sites with water and electric, and tent campsites. Comfort stations with showers are nearby. RV and tent campsites must be reserved online. The park also offers one-room lake huts with electricity, ceiling fans and screened windows. Outside the lake huts you will find grills, tables, water and restroom facilities. The park is near the Oklahoma Department of Wildlife Conservation's Paddlefish Research & Processing Center, which collects important biological data, processes paddlefish meat for anglers and salvages paddlefish eggs. The Paddlefish Research Center is open only a few months each spring. Contact the Oklahoma Department of Wildlife Conservation for more information about the Paddlefish Research Center.
