The Limestone Spring Shelter is located in Connecticut and is more than half a mile off the current route of the Appalachian Trail on a blue blazed trail that was once the main route of the Trail. This shelter is maintained by the Appalachian Mountain Club.

The Mohawk No. 1 Shelter is located on the Mohawk Trail in the Mohawk State Forest, a trail that was the route of the Appalachian Trail in Central Connecticut until the 1980s. This shelter was built by the Civilian Conservation Corps sometime in the 1930s. The 1968 Guide to the Appalachian Trail in Massachusetts and Connecticut describes the shelter as having a fireplace and no bunks. Hikers had to obtain permission from the Forest Ranger in the Mohawk State Forest before camping there.
