It's quite a trek to Aroostock State Park, nearly to the Canadian border, but it's worth the journey. I came here to attend the Crown of Maine Balloon Festival, which occupied my early mornings and evenings. During the day I would explore on foot or take the car through the countryside and enjoy the Amish farmlands.
Sites the sites are more or less level and wooded with some privacy, but there's less privacy if you are located in the middle of the loop and people take trails to the latrine in the middle. There is also a bathroom/showerhouse near the beginning of the campground loop, near the divide between the loop and the uphill section.
Near the back of the loop a trail heads up south peak for a short scrabble and nice loop hike. There's a rickety tent platform with great views of the valley at that end and a lean-to on the other end of the ridge. Threre's a playground for kids. Bring your kayak or canoe or they have some available to rent.
