Warren and Sussex County, NJ

Directions (Columbia end):

From I-80, take Route 94 north one mile; turn right onto Brugler Road; the trailhead is on the left after going over a small bridge; but continue to the next intersection; turn right on Warrington Road; cross the Paulinskill River; park on the left in a small parking lot.


As the name suggests, the right-of-way generally follows the valley of the Paulinskill River. Most of the trail lies on riverine or glacial deposits, but outcrops of Kittatinny limestone occur in the vicinity of Hainesburg Junction and Paulina, and some isolated patches of Jacksonburg limestone show up just north of Hainesburg Junction, northwest of the railroad bed and across the river. Between Halsey and Warbasse Junction, the railroad bed crosses the Martinsburg shale, which can be seen in the railroad cuts in the area, then passes again over Kittatinny limestone.

The Paulins Kill Watershed Group and its tributaries include townships from southern Sussex and northern Warren Counties and drain an area of about 157 square miles. The access sites include the Lafayette Township Park; Swartswood State Park; the Paulins Kill Wildlife Management Area and Columbia Lake Wildlife Management Area.  The watersheds in the watershed group include the Upper Paulins Kill, Trout Book, Lower Paulins Kill and Delawanna Creek and Stony Brook.



The name Paulins Kill makes reference to Paulina, daughter of a Hessian soldier.

This railroad route was originally used to transport agricultural products and Pennsylvania coal to the cities of eastern New Jersey and New York City.

1876  --  railroad operations begin when the Blairstown Railroad runs a line from Blairstown to Columbia. It was built by John I. Blair. 

1881  --  the Midland Rail buys the line to make it part of its line to Jersey City.  This line taken over by the New York, Susquehanna, and Western Railroad ( NYS&W).

1960  --  service ceases.

1962  -- the rails removed. 

1993  --  the State of New Jersey acquires the land.

2002 (July 31) --  Green Acres added the property formerly known as the Cedar Lake Horse Farm in Blairstown Township, Warren County to New Jersey's system of open space. The property, located northeast of Cedar Lake, comprises over 100 acres including a parcel of 42 acres between the Paulins Kill and the Paulins Kill Valley trail.  (Source:

Two training rings, a number of paddocks and pastures as well as three barns containing over 100 horse stalls were included with the purchase. The property will allow fishing access along the Paulins Kill, and acts as floodway protection for Blairstown and surrounding areas.  The Division of Parks and Forestry, Kittatinny Valley State Park will operate the facility. A management plan is being developed that will allow for a multi-purpose equestrian facility. Horse camping, trail rides, event training, boarding, and handicapped riding facilities, are among the activities being considered.  The property commands a spectacular view of the Kittatinny Ridge and when opened will allow excellent access to the 26 mile Paulins Kill Valley Trail.  (Source:


The Paulinskill Valley Trail follows the abandoned New York, Susquehanna, and Western Railroad right-of-way for 27 miles, beginning at Sparta Junction in Sussex County and terminating between Hainesburg and Columbia in Warren County. The overall area of the right-of-way is approximately 193 acres.

Fron southest to northeast some of the towns the trail goes through are Columbia, Hainesburg, Blairstown, Paulins Kill (Paulins Kill Lake here), Washingtonville, Halsey, Warbasse, and Sparta Junction.  

For most of its length the right-of-way is 60 feet wide, though it becomes wider where there were stations, junctions, and sidings.

Plants noted during a 1991-1992 Botanical inventory of the trail for the Paulinskill
Valley Trail Committee, with a few additions from a Delaware Valley Fern Society trip on August 19, 2000, and a Torrey trip on August 4, 2001, as noted. Note that this list includes only species found within the trail right-of-way.

Scientific nomenclature is generally per Gleason & Cronquist, Manual of Vascular Plants of Northeastern United States and Adjacent Canada - Second Edition (New York Botanical Garden, 1991).

English names from a variety of sources.

Note: Species frequency definitions are somewhat subjective, but in general an abundant species is one that is present and easily found in all areas of suitable habitat, and areas of its habitat are extensive. A common species is one that appears to be present at low density in all areas of suitable habitat, but may require some searching; or, plant may be present in good numbers (over a hundred plants total) but in only a few locations. An uncommon species is one that is not present in all areas of suitable habitat, but has more than ten individuals or small stations. An occasional species is one for which fewer than ten individuals or small stations were noted. Habitats listed for species are those most typical for the species, or the habitat in which a particular species was actually found, and not necessarily all the habitats in which a species occurs.
