So here is another post about another park in the area.
Greenwood is about 16 miles outside of state college off of rt 305 after Whipple Dam State Park.
This is a great place for summer fun. There is hiking, beach volleyball, a lake with a swimming beach, playground, snack bar in the summer, historic area, camping and probably lots more I don't know about.

We have really enjoyed visiting here. There facilities have recently been redone and are in great shape and the beach at the lake is great fun for the kids.
So if you are looking for a great day in the sun or a nice camping weekend or a hike, greenwood is the place for you.
There is also a fun grocery store, Couch's, that you can stop by on the way home for some delicious ice cream.
