Campgrounds and RV parks near St. Marys, WV

St. Marys sits on the Ohio River at the mouth of Middle Island Creek in Pleasants County, in the Mid-Ohio Valley of northwestern West Virginia. The town is the county seat and is best known for river access, kayaking on designated state water trails, and Middle Island, one of the few Ohio River Islands National Wildlife Refuge properties reachable by motor vehicle via a bridge from downtown. RV travelers use St. Marys as a base for both riverside recreation and the state-park country to the east. Castle Care Campground sits closest to town, while River Run at North Bend State Park lies roughly 20 miles east near Cairo, giving access to the 72-mile North Bend Rail Trail. Additional full-hookup options include Ashland RV Park and Blennerhassett RV Park across the river near Marietta and Belpre, Ohio, and American Way RV Park serves travelers on the Parkersburg side. Elevations in the area run roughly 600 to 800 feet, terrain is rolling, and cell service is stronger on ridges than in the valleys.

North Bend State Park operates two campgrounds. River Run has 49 sites, 26 with 30/50-amp electric and water hookups, and Cokeley has 28 RV sites with electric and water plus a coin-operated laundry. Both include Wi-Fi and ADA-compliant sites. Reservations for West Virginia state park campsites are made through the wvstateparks.com reservation system and can be booked up to 12 months in advance, with sites released on the first day of the month for the corresponding month a year later. Peak summer weekends and fall-foliage weekends fill early. Private parks such as Castle Care Campground, Ashland RV Park, American Way RV Park, and Blennerhassett RV Park are booked directly with the operator. GPS routing into North Bend can be unreliable for larger rigs, so calling the park office for the recommended approach via Harrisville is worthwhile.
