Frequently Asked Questions

How long is the Potomac Heritage National Scenic Trail (and where is it)?

As of early 2017, approximately 924 miles of existing and planned trails are recognized as segments of the Trail network (i.e., 833 existing, 91 planned). The Trail corridor spans two major watersheds and portions of five physiographic provinces between two points at the mouth of the Potomac River -- Point Lookout in southern Maryland and Smith Point on the Northern Neck of Virginia -- and the northern terminus of the Laurel Highlands Hiking Trail in western Pennsylvania. View the extent on the maps page.

How do trails become part of the Potomac Heritage National Scenic Trail network?

Authorized in the National Trails System Act, trails and routes are recognized as segments of the Trail network through "agreements for management"; Trail segment managers--typically agencies of government and organizations--and the Trail administrator execute a "memorandum of understanding" designating a specific trail or route. This document is also used to authorize use of the official Trail marker by Trail segment managers.

Where can I get the Trail stamp for my Passport to Your National Parks booklet?

Potomac Heritage NST Passport stamps are available at many visitor centers and other facilities throughout the Trail corridor. The Passport stamp booklet is available from Eastern National.

How can I get involved?

Volunteers are important to complete and maintain the PHT network. You can help by volunteering with a Trail management partner or an affiliated organization.
