Deer Mountain Campground is located in Connecticut Lakes State Forest, adjacent to the Connecticut River between Second and Third Connecticut lakes, Deer Mountain Campground is just five minutes south of the Canadian border. It is adjacent to the stretch of US-3 north of Pittsburg, referred to as Moose Alley, which makes it a prime location for moose viewing. The campground consists of a 25-site primitive campground. It opens for walk-in camping beginning in May.

High in the mountains of New Hampshire, you’ll find the Connecticut Lakes and headwaters of the Connecticut River. Starting as just a trickle in the small town of Pittsburg, the Connecticut River flows through a chain of lakes, the Connecticut Lakes, as it makes its way from the US-Canadian border in New Hampshire to Long Island Sound. Its journey of 400 miles begins at the height of land, becomes the diving border between Vermont and New Hampshire, then flows through the industrial valley of Massachusetts and into Connecticut before finding the sea.
