West of Newark and North of Phillipsburg near Columbia, the 6,200 acre Worthington State Forest has 26 miles of hiking trails. A stretch of the Appalachian Trail passes through the forest. Some of the most rugged terrain and splendid views of northern New Jersey are found in Worthington State Forest. A rocky and sometimes steep trail follows Dunnfield Creek from the Delaware River to Mount Tammany or hikers may choose to follow the trail to Sunfish Pond, one of the most popular sites in the area. Millions of years in the making, the pond was carved out by glacial forces during the last ice age and is one of fourteen rock-basin lakes between the Delaware Water Gap and the end of Kittatinny Ridge. A trail circles the pond, with many boulders and openings for resting and observation.
To reach the trailhead, take SR80 west to the last exit in New Jersey (Millbrook/Flatbrookville). At bottom of ramp, turn right. Office is three miles on left.
Overall, Worthington State Forest is the 17th most popular hiking trail of all 29 hikes in New Jersey.
