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.
Colorado Trail The Colorado Trail is a long-distance trail running for 486 mi from the mouth of Waterton Canyon southwest of Denver to Durango in Colorado, United States. Its highest point is 13271 ft above sea level, and most of the trail is above 10000 ft . Despite its high elevation, the trail often dips below the alpine timberline to provide refuge from the exposed, storm-prone regions above.
