Pymatuning State Park is Pennsylvania state park covering 21,122 acres and contains the 17,088 acres of Pymatuning Lake --- three-quarters of which is in Pennsylvania and one-quarter of which is in Ohio.
In its three campgrounds, Pymatuning has the most campsites in the state park system. Visitors can enjoy boating, fishing, swimming, camping and other recreational opportunities.
Pymatuning Lake was formed in the 1930s by a dam on the Shenango River, the lake features multiple beaches and camping areas in both states. The northeastern part of Pymatuning Lake, east of the spillway and three miles south of Linesville, is a protected gameland where colonies of 20,000 Canada Geese and many more ducks winter each year.
Because the lake crosses state lines, there is also a Pymatuning State Park in Ohio.
The park is generally open 24 hours a day to allow for overnight camping, but call for specifics.
Free, on-site parking is available.
