We had the entire campground to ourselves.  The actual campground is called Whitetail Campground, located on Deerfield Reservoir. 

Be aware that you must have water in your tank if you come in an RV.  The campground pumps do not have threaded hose connections. 

We hiked the Deerfield Lake Loop and found the signage to be missing in many places, causing us to take a 15+ mile hike instead of the advertised 11 mile hike.  The trail was overgrown and washed out (lost into the stream) in 5 or 6 places where we had to  cross.  It is not well traveled when you get 6 miles in.

There are two loops to the campground and we stayed in the one furthest from the lake (as it was full....) The bugs weren't too bad and we had a fire one evening.  The thunderstorms were pretty regular every afternoon and things stayed wet.

We would definitely return.
