Paulinskill Valley Trail

The Paulinskill Valley Trail is a rail trail along the Paulins Kill river in New Jersey. It is the sixth longest trail in the state at 27 miles (43 km). It was originally a right-of-way of the New York, Susquehanna and Western Railroad[2] and the Blairstown Railway. Vestiges of the railroad remain including several bridges, stations, mileage markers, telegraph poles and other railway artifacts.[3] There are also numerous benches and signs explaining the history of the trail and its artifacts.[4] Over 560 species of birds have been sighted on the trail as well as a multitude of other wildlife.[5]

The Paulinskill Valley Trail intersects the Sussex Branch Trail at Warbasse Junction just north of Newton[6] as well as the 3.5-mile Great Valley Rail Trail, along Paulins Kill Lake.[7][8]

The trail is frequented by hikers, bicyclists, joggers and people who are just out for a stroll. Horseback riding is also permitted. Access is denied to motor vehicles, however, although trailheads typically provide some modest amount of parking. Although the trail is generally well-maintained from the Paulinskill Viaduct north, south of that location the quality of the trail is somewhat uneven. Over the years there have been surprisingly few encroachments onto the right-of-way. The most notable encroachment is at Blairstown Airport where the trail ceases to exist for about a half-mile (1 km). Signage directs the hiker to where the trail continues.
