About
Cooney State Park sits on Cooney Reservoir, a 770-acre impoundment 22 miles southwest of Laurel in Carbon County. The reservoir is renowned for excellent walleye and rainbow trout fishing and serves as a popular destination for boating, water skiing, jet skiing, and swimming. The surrounding landscape offers scenic views of the Beartooth Mountains. The park features five campground loops with 82 total campsites plus three group use areas. Marshall Cove Campground offers the most developed amenities including metered showers and flush toilets. Nineteen sites have electric hookups with 15, 20, 30, and 50 amp service available, and some sites offer water and sewer connections. Pull-through sites accommodate larger RVs. All campgrounds have vault toilets, drinking water (seasonal), fire rings, and picnic tables. Beyond camping, the park provides multiple boat ramps, docks, a fish cleaning station, swimming beach, playground, volleyball court, and horseshoe pits. Winter activities include ice fishing and cross-country skiing. A camp host is present during the busy season, and ADA-accessible sites are available.
