    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.

    I stayed in one of the rustic cabins and it was perfect. The bed was soft, the heat was warm, and there was a USB plug to charge my phone in the cabin. The bathhouse had hot showers ($1 for 12 minutes) and laundry ($1 for wash, $1 for dry). A great stop on the Cohos Trail.

    We stayed at camp site 9a. The location was great. No cell service out here with Verizon. It was a nice park to walk around. Definitely a great place if you have atv and snowmobiles. Bathrooms were clean and stocked. Showers cost money (4 quarters for 12 min shower).

    This is my favorite NH State Park so far because it was rustic and beautiful and gave me a sense of freedom as I imagine NH should have. The campground is small and well groomed with good access to Diamond Pond. The office staff was good and helped me rent a kayak and plan trips to nearby waterfalls. Showers were clean and easy to access. The pond is not for swimming but offers superb beauty for boats and nature watching. We enjoyed the summer trip and hope to return in the fall or winter.
