Maurice K. Goddard State Park spreads across 2,856 acres in Mercer County, Pennsylvania, centered around the stunning 1,860-acre Lake Wilhelm — one of the largest lakes in the state park system. Established in 1972 and named after the former Secretary of the Department of Forests and Waters who championed Pennsylvania’s state park expansion, this park delivers a genuinely impressive lakeside experience in the northwestern corner of the state.

Lake Wilhelm is the main draw here. The lake’s size and no-horsepower restrictions on certain sections make it outstanding for fishing, particularly for walleye, muskellunge, largemouth bass, and crappie. A 12-mile hiking trail loops the entire lake, offering a solid day hike through mixed hardwood forests with frequent water views. In winter, cross-country skiing and ice fishing take over, and the frozen lake draws a dedicated crowd.

Boating is excellent, with multiple launch areas and rental options available seasonally. The park also features picnic areas, a swimming beach, and accessible trails for visitors of all abilities. Birdwatchers will find the marshy coves productive, especially during spring and fall migration when waterfowl congregate in large numbers.

Late spring through early fall is the prime window, with summer weekends bringing the most activity around the beach and boat launches. Fall foliage season turns the lake loop trail into one of Mercer County’s best walks.

Whether you’re casting a line at dawn or hiking the full perimeter, Goddard State Park rewards visitors who come ready to spend a full day outdoors.
