Vestiges of the railroad remain including several bridges, stations, mileage markers, telegraph poles and other railway artifacts like buildings both still standing and ruined. There are also numerous benches and signs explaining the history of the trail and what remains of the railroad. Over 200 species of birds have been sighted on the trail as well as a multitude of other wildlife. The Paulinskill Valley Trail intersects the
Sussex Branch Trail at Warbasse Junction just north of Newton. as well as the 3.5-mile Great Valley Rail Trail, along Paulins Kill Lake. 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. == History ==
