Northampton County Major Trail Systems
Northampton County is a hub for major trail systems such as the Nor-Bath Trail, D&L Trail, September 11th National Memorial Trail and Liberty-Water Gap Trail connecting to over 300-miles of land and water trails.
Nor-Bath Trail 
Take a walk on this historic rails-to-trails walking and bicycle path – on an abandoned Northampton-Bath Railroad line. Nor-Bath Trail is a 10.4 mile out and back trail located near Northampton, Pennsylvania. The trail is good for all skill levels and primarily used for walking, biking, cross-country skiing and interpretive education. The trail crosses Dry Run and Catasauqua Creek. Parking is available at a trailhead on Savage Road and within the adjacent Wayne A. Grube and Bicentennial parks. The trail crosses through the Allentown Farm State Hospital National Historic District Eligible site.
The Delaware & Lehigh Canal National and State Heritage Corridor (D&L) is a 165-mile (266 km) National Heritage Area in eastern Pennsylvania in the United States. It stretches from north to south, across five counties and over one hundred municipalities. It follows the historic routes of the Lehigh and Susquehanna Railroad, Lehigh Valley Railroad, the Lehigh Navigation, Lehigh Canal, and the Delaware Canal, from Bristol (northeast of Philadelphia) to Wilkes-Barre in the northeastern part of the state. The backbone of the Corridor is the 165-mile (266 km) D & L Trail. The Corridor's mission is to preserve heritage and conserve green space for public use in Bucks, Northampton, Lehigh, Carbon, and Luzerne counties in Pennsylvania. It also operates Hugh Moore Historical Park & Museums, which includes the National Canal Museum.
The September 11th National Memorial Trail
The September 11th National Memorial Trail will eventually be a 1,130-mile non-motorized hiking and cycling trail; although initially it will have on-road sections connecting the memorials. The trail is shaped as a triangle forever connecting together the Flight 93 National Memorial, the Pentagon Memorial and New York City's National September 11 Memorial. 
The September 11th National Memorial Trail can be divided into three major legs:
From the Pentagon to New York City based on the East Coast Greenway route
From the Pentagon to the Flight 93 memorial based largely on the Canal towpath and the Great Allegheny Passage
From Garrett, PA to New York City using many existing trails, and connecting a variety of historic and patriotic locations along the way.
Liberty-Water Gap Trail
The Liberty-Water Gap Trail connects two national landmarks at each end: the Delaware Water Gap and the Statue of Liberty. This is a 130 mile linear park that runs the width of New Jersey. There are six trail segments:
- Hudson River Waterfront Walkway - Liberty State Park, Jersey City
- East Coast Greenway - Jersey City to Newark
- Lenape Trail - Essex County
- Patriots' Path - Morris County
- Sussex Branch Trail - Sussex County
- Paulinskill Valley Trail - Sussex & Warren Counties
The Paulinskill Valley Trail segment has recently been connected to Portland, PA.
Northern Tier Trail 
The planned Northern Tier Trail is an east to west 35-mile planned trail connection in the northern14 municipalities, along the Blue Mountain (regionally known as the Kittatinny Ridge) in Northampton County from Walnutport to Portland Borough. When complete, it will connect the outdoor recreation, tourism, and economic development.
