There is a lot of history here and a lot ot learn about Native Americans, geology, plants, animals, etc. Great park for a weekend or a whole week. We mostly did hiking and canoeing, also lots of fishing. Great hiking trails for kids since there are a lot of neat geologic features, bridges, etc. to keep their attention during a hike.
Yay: This park has a lot of extras like playing fields, kayak rentals, ranger programs, educational signage (history and nature), etc. We stayed at a tent site near the little lake and it was just lovely. There are also adorable cabins to rent.
**Nay: some campsites are a little crowded but nothing unusual. **
Surprise: absolutely beautiful old stonework, bridge, buildings, etc. add so much to the natural scenery!
