Twin Bridges State Park is located on the north side of the Grand Lake o' the Cherokees in northeastern Oklahoma. It was named for the two (or "twin") bridges which carry U.S. Highway 60 over arms of the lake which connect to the Neosho River and the Spring River. Twin Bridges State Park is known for its quiet country atmosphere and excellent fishing for trophy-sized bass, catfish, bluegill, and spoonbill. A fishing center with bait, tackle, and enclosed fishing dock is located within the park. 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 semi-modern RV sites to tent camping and offer comfort stations with showers. The park also offers one-room lake huts with electricity, ceiling fans, and screened windows, grills, tables, water, and restroom facilities. The park is also home to the Wildlife Department's Paddlefish Research & Processing Center which collects important biological data, processes paddlefish meat for anglers, and salvages paddlefish eggs. The Paddlefish Research & Processing Center is open from February 15 to May 15.
