Families with children gravitate toward this KOA near Williamsport, drawn by the on-site activities and creek access. The campground sits alongside a waterway where campers can fish, and the property includes a small diner serving breakfast and a general store for basic supplies. Staff organize regular activities including crafts and entertainment shows that keep younger campers engaged throughout their stay.
Sites accommodate RVs up to 40 feet with full hookups, though maneuvering larger rigs requires patience on the narrow, winding internal roads. Cindy D. notes the campground has "a homey feel" with upgraded fire pits featuring swivel grills instead of standard fire rings. The single bathhouse serves the entire campground, which some campers find inconvenient during busy periods. Several reviewers mention the facility shows its age but remains functional.
The creek provides a natural soundtrack and fishing opportunities, while the property includes farm animals that children enjoy visiting. Sites vary in size and spacing, with some positioned perpendicular to access roads creating tight fits during peak times. Weekend arrivals often find the campground at capacity, particularly during fall when seasonal decorations add to the family atmosphere.
Access requires following KOA's specific directions rather than GPS routing, as standard navigation can lead to rough road conditions. The campground operates seasonally from March through November, with muddy conditions possible after heavy rains. Patrick M. found "sites, amenities, and bathrooms/showers were all clean and well kept" during his visit. Reservations are recommended, especially for weekend stays when the property fills quickly.
Campers seeking alternatives can consider Pilot Travel Center — Hagerstown for a more basic overnight stop with easier big-rig access.
