As with most CT state campgrounds, there are no utilities available for the sites. Make sure your trailer battery is charged and your water tank is full. There are water spigots available. Very clean campground and the bathhouse is well maintained.
The main center camping area is pretty much open, so watch out for those hot summer days... they'll heat you up in no time. Driving up through the 2 other camping loops showed them as being nice too, but with more shade trees. I don't think there is a bad site in the place.
