We hope you will enjoy exploring the Pennsylvania Highlands website and delve deeply into the substantial conservation and trail-planning information that has been assembled into one place. The Pennsylvania Highlands Trail Network as envisioned is being co-located with many existing trails in the region, from the D&L Trail in the easternmost Highlands to the Mason Dixon Trail west of the Susquehanna River. The Pennsylvania Highlands Trail Network (PHTN) will link these trails and many more across the 13-county Pennsylvania Highlands region.
