Sugar Ridge Campground is an excellent campground. I actually have no negative comments about the facility. It appears that a lot of the sites are seasonal. All the sites are very well maintained and spacious. The campsite we stayed on was very private and the bathroom and free showers were clean. The campground offers many amenities such as, two pools, two playgrounds, rec hall, mini golf course (small fee), daily activities, bike rentals, access to the Lamoille Bike Trail, hiking trails with beautiful views right on the grounds and a fishing pond, since it's on private land you do not need a fishing license.
If you do not want to leave the campground you do not need to as there is plenty to keep everyone busy. If you are looking to do some exploring St. Johnsbury VT is about 15 minutes away. Cabot Cheese Factory is about 30 minutes away. There are also numerous hiking trails and outdoor activities in the area. If you are looking for a campground that offers a lot of amenities as well as close to other activities I highly recommend staying here. Website
