Avid walkers and hikers have a number of scenic trails to choose from in Northeast Tennessee. The granddaddy of them all is the Appalachian Trail, which travels through 14 states and over 2,100 miles from Springer Mountain, Georgia, to Katahdin, Maine. The hiking trail crosses into Tennessee near the Nolichucky River, just outside of Erwin. The world-famous trail has multiple access points in the Johnson City area. Another one of the most enjoyed trails in the region is the Tweetsie Trail, which is a multi-purpose path that stretches 10 miles between Johnson City and Elizabethton. It is Tennesseeâs longest rails-to-trails project and runs along the the track of the former East Tennessee & Western North Carolina Railroad through Washington and Carter counties.
