About This Trail

The Bethlehem, Saucon, and Upper Bucks Rail Trail strings three rail trails into one 15 mile corridor on the former North Pennsylvania Railroad. It starts beside the old Bethlehem Steel works, follows the South Bethlehem Greenway through the city, then picks up the Saucon Rail Trail along Saucon Creek through Hellertown, Center Valley, and Coopersburg. The Upper Bucks Rail Trail carries it the last stretch into Springfield and Richland townships, ending at Veterans Park outside Quakertown. The grade is rail flat, rising gently the whole way south. It is paved in Bethlehem, crushed stone beyond, with one long boardwalk in Bucks County. Parks with restrooms mark most trailheads.

RailTrailWx TIPS

Bethlehem, Saucon, & Upper Bucks Rail Trail

Your comfort. Prognosticated.

  • The Bethlehem end sits about 300 feet lower than Veterans Park, so heading south is one long, faint climb and the return north is a rolling coast. You will feel it as minimal effort, not as a hill.
  • The trail runs mostly north to south with open fields along much of it. A south wind is a headwind on the climb toward Quakertown and a tailwind toward Bethlehem; shaded sections give some cover from a crosswind.
  • About half the corridor is under trees, in stretches rather than one long tunnel of shade. Expect sun and shade to trade off every mile or two, with the most open ground in the farm country south of Center Valley.
  • In Springfield Township an 800 foot wooden boardwalk carries the trail across low ground. Wood decking is slick under frost or wet leaves, so careful there in the shoulder seasons.
  • The Saucon section is open dawn to dusk only. E-bikes are allowed within the usual class limits, horses and motorized vehicles are not, and dogs must be leashed.

Trivia

  • The North Pennsylvania Railroad cut the trip between Philadelphia and Bethlehem from eight hours by stagecoach to three hours by rail.
  • Wooden mileage posts from the original North Penn Railroad still stand along the Saucon section.
  • The Upper Bucks section crosses an 800 foot boardwalk in Springfield Township built of Cumaru, a Brazilian teakwood chosen for durability.
  • Bucks County paid the full 1.5 million dollar cost of the Upper Bucks Rail Trail from its Act 13 Marcellus Legacy fund.
  • SEPTA spent 2 million dollars in 2008 just to pull the rails and ties out of the Saucon corridor before leasing it to the towns for thirty years.
  • The Highlands Trail, a long distance route across the Pennsylvania Highlands, runs on the Saucon Rail Trail for all 7.5 miles of it.
  • Bethlehem bought the last 0.9 mile of rail bed from Norfolk Southern in 2025, closing the gap between the Greenway and Hellertown.

History

Ground was broken for the North Pennsylvania Railroad in Philadelphia on July 2, 1855. Three years later the line reached Bethlehem, and stagecoach trips that took eight hours now took three by train. The road hauled anthracite south from the Lehigh Valley, plus iron ore, grain, groceries, mail, and commuters. In 1879 the Philadelphia and Reading leased it, and the corridor became the Reading's Bethlehem Branch. Coal traffic peaked around the First World War. The Reading was folded into Conrail in 1976. SEPTA kept running commuter trains to Bethlehem until July 26, 1981, ending 124 years of passenger service. The last train ran in 1984. Bethlehem bought about 2.5 miles of the rail bed from Norfolk Southern in 2008 for the South Bethlehem Greenway. The same year SEPTA paid to lift the rails and ties from the Saucon stretch, and in 2009 it leased that corridor to Hellertown, Coopersburg, and the two Saucon townships for thirty years. The first phase of the Saucon Rail Trail opened in 2011 between Hellertown and Upper Saucon Township, and the trail later grew to 7.5 miles. Bucks County built the Upper Bucks Rail Trail south from Coopersburg and opened it on November 19, 2020. In 2025 Bethlehem bought the final 0.9 mile from Norfolk Southern to tie the Greenway to the Saucon trail at Hellertown.
