Air Line State Park Trail

Air Line State Park Trail is a rail trail and linear state park located in Connecticut. The trail is divided into sections designated South, North a piece of the East Coast Greenway, and the Thompson addition. An additional 3.6-mile spur to Colchester is sometimes designated as part of the Air Line trail. At the Massachusetts state line, the trail connects to the Southern New England Trunkline Trail, a 22-mile-long trail to Franklin, MA built on the same right-of-way. Since 2018, the town of Portland, Connecticut has also maintained a 2.3-mile portion of the Air Line trail, connecting to the southern end of the state park at the town line with East Hampton.
