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.
Grande Traversata delle Alpi The Grande Traversata delle Alpi (GTA) is a long-distance hiking trail in the Italian region of Piedmont. In about 1,000 km and 55 day hikes, it runs through the arc formed by the western Alps from the Pennine Alps through the Graian and Cottian Alps to the Maritime and Ligurian Alps. There are a number of transverse valleys along the route. Day hikes typically connect high-lying valley communities with each other via historic pass routes.
