About This Trail

The Lehigh Canal (South) segment of the D&L Trail covers about 41 miles of the Lehigh River valley from Weissport to Hugh Moore Park in Easton, mostly on the Lehigh Canal towpath with stretches of former railroad bed. It squeezes through Lehigh Gap in the Kittatinny Ridge, where the Appalachian Trail crosses, then follows the canal past its locks through Slatington, Northampton, Catasauqua, Allentown, Bethlehem, and Freemansburg to the Chain Dam. The surface is mostly crushed stone with paved city sections and one on-road link on North Dauphin Street between Hanover Township and Allentown. The D & L Trail: Lehigh Canal (North) segment lies upstream; the D & L Trail: Delaware Canal Towpath segment continues from Easton.

RailTrailWx TIPS

D & L Trail: Lehigh Canal (South)

Your comfort. Prognosticated.

  • Lehigh Gap cuts through the Kittatinny Ridge. The gap funnels the wind; expect a gusty mile between the East Penn boat launch and Slatington on any breezy day.
  • Between Hanover Township Canal Park and Kimmett's Lock the towpath is gone and riders share North Dauphin Street; Hanover Township and Allentown planned paths to close the gap with construction starting in fall 2025.
  • The grade is towpath flat, dropping only about 250 feet over 40 miles, so wind and surface matter more than climbing.
  • Services are dense from Northampton to Bethlehem and thin north of Slatington; Weissport to Lehigh Gap is about 8 miles of bog and pond habitat with only the East Penn launch in between.

Trivia

  • At Lehigh Gap the New Jersey Zinc Company smelted zinc from 1898 to 1980, and its fumes stripped the Kittatinny Ridge bare; the EPA named about 3,000 acres one of the nation's first Superfund sites.
  • The Lehigh Gap Nature Center bought 756 acres of that barren mountain and reseeded it with a mix of 12 native prairie grasses, mushroom compost, and limestone.
  • The Appalachian Trail crosses the D&L at Lehigh Gap, the only place the two long trails meet.
  • Slatington's Fireman's Drinking Fountain, a statue on the main street, dates from 1909.
  • Between Allentown and Bethlehem, the trail runs a narrow strip with the Lehigh Canal on one side and the Lehigh River on the other.
  • Weissport, at the north end, was the canal's boatyard town, founded in 1792 by Colonel Jacob Weiss.
  • The Lehigh Coal and Navigation Company kept the Lehigh Navigation running until 1932, when maintenance costs finally outran revenue.

History

Josiah White and Erskine Hazard founded the Lehigh Coal and Navigation Company in 1818 to move anthracite out of the hills at Mauch Chunk. Their Lehigh Canal was rebuilt for two-way traffic from 1827 to 1829, 46 miles from Mauch Chunk to Easton. Pennsylvania dug the Delaware Canal from Easton to Bristol between 1827 and 1832, and the first coal boat reached Bristol that July. Upstream, the company dug the canal on through the Lehigh Gorge to White Haven by 1843 and chartered the Lehigh and Susquehanna Railroad to reach Wilkes-Barre. In June 1862 a dam failure above White Haven washed the gorge canal out for good. The Lehigh and Susquehanna replaced the drowned canal and the Central Railroad of New Jersey leased it in 1871, while Asa Packer's Lehigh Valley Railroad hauled coal down the far bank. The last paying boat left the Delaware Canal in October 1931, and the company closed the Lehigh Navigation in 1932. Pennsylvania made the Delaware Canal a state park in 1940. The Central Railroad of New Jersey gave up its gorge line in 1972. Lehigh Gorge State Park took the empty rail bed in 1980, and Congress created the Delaware and Lehigh National Heritage Corridor in 1988. Its namesake nonprofit has joined towpaths and rail beds into the 165 mile D&L Trail since. This segment is the long middle of the Lehigh Canal, consisting of both towpath and rail bed from Weissport through Lehigh Gap, Slatington, Allentown, and Bethlehem to the Chain Dam at Easton.
