Pros: clean bathroom facilities, nice property and lake access, playground for the kids, quiet, easy access to ATV trails
Cons: no cell service because it's really out in the middle of nowhere (maybe you don't consider this a con), camping lots have no privacy between them, rules are you can only have 2 vehicles on your camping lot (2 4 wheelers count as a vehicle and 1 sxs counts as a vehicle), state park store is located 1/4 mile down the road and doesn't have a lot of essentials, no other conveniently located stores or liquor store (that I'm aware of because I didn't have cell service)
Place was beautiful would like to see a sink added in bath houses where people can do their dishes. Boats and kayaks weren't available to rent this was disappointing. Staff was very friendly. Did a couple of hikes around Dixville Notch.
