This is a small park, but it's a good spot to stay to explore the area (nearby Mt. Ascutney State Park, Harpoon Brewery, the American Precision Museum, etc.).
Kayaking on the river is the big draw, which is a great place to be on a hot day.
The one hike across the road is steep so it would not be suitable for small children, but walking around the campground is very pleasant.
The grounds and facilities are immaculate.
The campground is small and quiet. The pond is clean and swim-able and great for kayaks/canoes (near Glen Lake and Lake Bomoseen for boating and more kayaking/canoeing). There are a couple of small hikes in the park and more hiking nearby. The beach is small, but it is never busy. No hookups but the bathrooms are clean and the showers ($) are hot.
