Dry Run Creek / Rockhopper Trails
Just north of Mercer-Hunterdon County line is the Dry Run Creek trailhead, 20 minutes or so north of downtown Trenton by car. Maintained by the D&R Greenway Land Trust, it’s a delightful, 1.2 mile trail that descends into Dry Run Creek* and then climbs about 230 feet to 518 and another parking lot. There, if you look directly across the road, you can continue on the Rockhopper Trail. Altogether, you can walk an entertaining 10+ mile round trip hike.
