Sussex Branch Trail New rail trail opened By bromaine in 6/5/2012 4:15:21 PM | A new rail trail has opened that connects the Sussex Branch Trail to the Paulinskill Trail. It is a 13.5 mile loop. Real nice ride. My wife and I road it Sunday. We started at the Warbasse Junction. Rode the Sussex Branch to the new trail I think it is the Leigh New England Line in Augusta. This trail follows the Paulinskill River. Then to the Paulinskill Trail and back to the Warbasse Junction. It was very well marked. There is a map of the loop at Warbasse Junction.
