This was a nice place for a day trip, although there seemed to be enough to do and see if you wanted to stay longer. They have rental cabins, some of which were close to the Potomac River (The Potomac River Retreat house.) There was a $3.00 vehicle parking fee for the day. We went to the pool which was along the river; there was a $4.00 per person per day fee. The pool was quite nice with bathrooms, showers, lifeguards, diving boards, and a slide. They also had a snack stand near the pool. There are also miles of trails. They also have lots of picnic tables. There were two picnic pavilions available for rent for large groups. This park was was worthwhile visiting.
