The Watchung Reservation History Trail is a 6-mile trail that visits and identifies sites of historic interest in Union County’s Watchung Reservation, a 2,000+acre preserve located in the northern portion of the County. The stops along the History Trail recall features from the early years of the Watchung Reservation, or describe uses of the land before it was incorporated into the park. The trail is marked with pink blazes, with signs on posts along the trail identifying the location of each site. The trail is designed to start and end at the Trailside Nature & Science Center, but can also be accessed from parking areas at the Deserted Village of Feltville and Lake Surprise.
