This trail is a classic with stellar vistas and classic sections such as the "Thousand Steps". Once upon a time there was the Mid State Trail. Then there was the Tuscarora Trail. Next there was the idea to LINK the two trails together! And thus (short version), the Link Trail was born. This guidebook is your best resource for traveling the 71 miles of the Link (now named the "Standing Stone") Trail. Author: The Keystone Trails Association.
