Sinnemahoning State Park


Featuring beautiful deep valleys and home to the rarely seen elk and bald eagle, Sinnemahoning State Park is a perfect destination for RV travelers who love mountains. The park features 1,910 acres of beautiful scenery, outstanding wildlife habitat and is truly a gorgeous place to visit. The history of the park dates back to when Native Americans began living in the area around 10,000 to 12,000 years ago. They came to be in the area by following the receding glaciers and found that the area had a great supply of fish, wildlife, berries and nuts. The Sinnemahoning area was left mostly unsettled and wild due to the natives suffering diseases and the ill effects of the American Revolutionary War until the late 19th century. During this time is when the logging boom took off and old growth rainforest was cut down and floated down Sinnemahoning Creek to various other rivers.

The first amenities in the park were built in 1955 when the 142-acre man made George B. Stevenson lake was constructed by the Commonwealth of Pennsylvania as part of the flood control project on the West Branch Susquehanna River. The park officially opened in 1962 and in 2011 a visitor center and office opened that is known as the Wildlife Center at Sinnemahoning. The building features interpretive exhibits and opportunities to view wildlife throughout various times of the year. Recreational actives are aplenty in Sinnemahoning State Park with recreational boating, fishing and ice fishing being popular on the lake. Visitors can also hiking, hunting and participate in winter recreation. Camping at Sinnemahoning State Park is available in one campground that has 35 sites available from the second weekend of April and closes in mid-December. Peak season at Sinnemahoning State Park runs from April until the end of October.
