For general info, they do have at least one group site that is way at the dead end of a dirt road with lots of room for multiple tents and a firepit. Probably a good place for a mini gathering. The swimming area comes directly off of Ice Gulch and Perkins brook, there is a so called warming pool that attempts to prewarm the water but it is decidedly "refreshing" most of the year.
The Gorham Town Forest is at the end of Jimtown Road and makes for some good walking, there is a connection to the south end of Ice Gulch, but the trail is only marginally maintained.
The campsites on the south side of the road are decidedly more "car campish"
The closest store Moes Variety at the intersection of Rt 2 and 16. With Shaws shut down, the beer selection in town has gone down.
