Appalachian Trail The Appalachian National Scenic Trail, generally known as the Appalachian Trail or simply the A.T., is a marked hiking trail in the Eastern United States extending between Springer Mountain in Georgia and Mount Katahdin in Maine. The trail is about 2,200 miles (3,500 km) long, though the exact length changes over time as parts are modified or rerouted. The Appalachian Trail Conservancy claims that the Appalachian Trail is the longest hiking-only trail in the world. More than 2 million people are said to do at least one day-hike on the trail each year.
Tunxis Trail The Tunxis Trail is a 79 mi "Blue-Blazed" hiking trail "system" that traverses the western ridge of the central Connecticut valley. The mainline (official "Blue" and "non-dot") trail is not completely contiguous, notably there are two gaps of several miles (between the Southington and Burlington sections and between the Burlington section and the Nepaug section).
