With a pristine beauty that incorporates both the sparkling waters of the tranquil Greenwood Lake and the stunning peaks of the Seven Mountains, you’d probably struggle to believe that Greenwood Furnace State Park was once a prosperous mining company.

Where previously the area was filled with huge smoke stacks that covered it in dust and soot, the park is now a lush and vibrant green space that is full of native flora and fauna.

Offering a wide range of cultural, historical and recreational attractions, this PA state park acts as a haven for those who enjoy a wide range of recreational activities. This includes boating, fishing, swimming and hiking. As well as picnicking, hunting and winter activities like cross-country skiing and snowmobiling.

Laying adjacent to the 80,000-acre Rothrock State Forest, the park is the perfect place for a weekend nature getaway, or week-long vacation.

If you are coming from Pittsburgh, Philadelphia, Washington, Baltimore or New York, you’ll be pleased to know the park also has a good selection of RV and tent campsites available too.
