What passes through Lyme, New Hampshire and is the longest hiking-only trail in the world?
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.
International Appalachian Trail The International Appalachian Trail (IAT; French: Sentier international des Appalaches , SIA) is a hiking trail which runs from the northern terminus of the Appalachian Trail at Mount Katahdin, Maine, through New Brunswick, to the Gaspé Peninsula of Quebec, after which it follows a ferry route to Newfoundland, and then continues to the northern-easternmost point of the Appalachian Mountains at Belle Isle, Newfoundland and Labrador.
