Deer Mountain Campground offers 23 primitive campsites located adjacent to the Connecticut River between Second and Third Connecticut Lakes, providing direct access for fishing and paddling enthusiasts.

The campground features basic amenities including fire rings, picnic tables, pit toilets, and drinking water, with sites available for tent camping, pop-ups, and one cabin, operating seasonally from late May through mid-October.

Its location in Connecticut Lakes State Forest near "Moose Alley" on Route 3 makes it an ideal base for exploring the remote north country, though visitors should note there are no electrical hookups and limited cell service.
