From the northwest corner of the parking area, proceed west to the stone Cooper Mill. The mill, built in 1826, is open for tours in the summer and on weekends in the spring and fall. Descend the stairs alongside the mill and continue south on the blue-blazed Black River Trail, part of the Patriots’ Path system (also blazed with the path-and-tree logo), which crosses several tributary streams on wooden bridges. About a third of a mile from the start, the trail turns left onto an abandoned railroad grade – the former route of the Hacklebarney Branch of the Central Railroad of New Jersey, built in 1873 to carry iron ore from mines along the river and abandoned in 1900. The trail follows this railroad grade for the next mile.
Half a mile from the start, you’ll pass Kay Pond (formerly known as Hacklebarney Pond) on the right. Here, the railroad had to be blasted through a rock cut, and the drill marks from the blasting may still be seen in the rock. The small building at the south end of Kay Pond was once used to store ice cut from the pond in the winter.
After passing the stone dam at the end of the pond, the trail goes by a fenced-in area to the left. This is the site of the former Hacklebarney Mine, where a considerable amount of iron ore was mined in the last quarter of the nineteenth century. Just beyond, the trail reaches a bridge over the river and turns left, continuing to follow along the river. Soon, the railroad grade ends and the trail continues on a slightly rougher footpath parallel to the river.
About 1.2 miles from the start, after crossing two wooden footbridges over tributary streams, the trail reaches abandoned concrete abutments in the river – the remnants of a former bridge. Here, the trail bears left and begins to head uphill. It bears left at the next fork and soon begins to parallel Chubb Brook. The trail now curves right and continues to climb more steeply.
At the top of the climb, the trail reaches a junction in a clearing, marked by a signpost. Here, the red-blazed Conifer Pass Trail comes in from the right. Turn left, now following both blue and red blazes, then turn left again at the next intersection. You'll pass open fields on the right and come to a parking area, with the Kay Environmental Center on the right.
Pass just to the left of the Environmental Center (note a Patriots' Path blaze on a tree to the left of a fence) and continue on the blue-blazed Bamboo Brook Trail. The trail follows a wide grassy path between fields and continues on a grassy woods road. It turns left at a T-intersection, then bears right to join the paved entrance road. It continues along the road for a quarter mile, then turns right onto Pottersville Road. After following Pottersville Road for 750 feet, the trail turns left (opposite a private home) and reenters the woods on a footpath.
In another quarter mile, the trail begins to climb the hillside on a rocky path. After reaching the top of the hill, the trail descends to a junction with the red-blazed Conifer Pass Trail (marked by a signpost). Turn right and follow the red-blazed trail as it descends to recross Pottersville Road.
On the other side of the road, the trail enters a beautiful pine forest and descends past old stone walls to cross Cedar Brook on rocks. It ascends on switchbacks through a grove of fir trees, continues through a deciduous forest to the crest of the rise, and descends once again to the Black River, passing two mine pits on the right along the way.
The red-blazed trail now heads north through the rocky gorge of the Black River, running directly along the river for part of the way. This wild and spectacular section of the river is an interesting contrast to the relatively placid section that you followed at the start of the hike. After about a quarter of a mile, the trail begins to climb out of the gorge. At the top of the climb, it turns right at a T-intersection, bears sharply left in 100 feet, then bears left again at a Y-intersection.
The trail continues high above the river, with views of the river below through the trees. In another 0.4 mile, you’ll reach a T-intersection with a wide dirt road. The red blazes turn right, but you should turn left and follow a green-blazed trail that heads downhill along the woods road. In another 750 feet, you’ll reach a Y-intersection. Here, the green blazes bear left, but you should bear right and continue ahead on the woods road, now unmarked, which heads north, parallel to the river. Continue along the road for another 600 feet to its end at the blue-blazed Black River Trail. Turn left and follow the Black River Trail north along the Black River for 1.2 miles, retracing your steps to the Cooper Mill parking area where the hike began.

Whether you are going for a day hike or backpacking overnight, it is good practice to carry what we call The Hiking Essentials. These essentials will help you enjoy your outing more and will provide basic safety gear if needed. There may also be more essentials, depending on the season and your needs.
Hiking Shoes or Boots
Water - Two quarts per person is recommended in every season. Keep in mind that fluid loss is heightened in winter as well as summer. Don't put yourself in the position of having to end your hike early because you have run out of water.
Map - Know where you are and where you are going. Many of our hiking areas feature interconnecting network of trails. Use a waterproof/tear-resistant Tyvek Trail Conference map if available or enclose your map in a Ziplock plastic bag. If you have a mobile device, download Avenza’s free PDF Maps app and grab some GPS-enhanced Trail Conference maps (a backup Tyvek or paper version of the map is good to have just in case your batteries die or you don't have service). Check out some map-reading basics here.
Food - Snacks/lunch will keep you going as you burn energy walking or climbing. Nuts, seeds, and chocolate are favorites on the trail.
Sunscreen and insect repellent
Rain Gear and Extra Clothing - Rain happens. So does cold. Be prepared for changing weather. Avoid cotton--it traps water against your skin and is slow to dry. If you are wearing wet cotton and must return to your starting point, you risk getting chills that may lead to a dangerous hypothermia. Choose synthetic shirts, sweaters and/or vests and dress in layers for easy on and off.
Compass - A simple compass is all you need to orient you and your map to magnetic north.
Light - A flashlight or small, lightweight headlamp will be welcome gear if you find yourself still on the trail when darkness falls. Check the batteries before you start out and have extras in your pack.
First Aid Kit - Keep it simple, compact, and weatherproof. Know how to use the basic components.
Firestarter and Matches - In an emergency, you may need to keep yourself or someone else warm until help arrives. A firestarter (this could be as simple as leftover birthday candles that are kept inside a waterproof container) and matches (again, make sure to keep them in a waterproof container) could save a life.
Knife or Multi-tool - You may need to cut a piece of moleskin to put over a blister, repair a piece of broken equipment, or solve some other unexpected problem.
Emergency Numbers - Know the emergency numbers for the area you're going to and realize that in many locations--especially mountainous ones, your phone will not get reception.
Common Sense - Pay attention to your environment, your energy, and the condition of your companions. Has the weather turned rainy? Is daylight fading? Did you drink all your water? Did your companion fail to bring rain gear? Are you getting tired? Keep in mind that until you turn around you are (typically) only half-way to completing your hike--you must still get back to where you started from! (Exceptions are loop hikes.)
Check the weather forecast before you head out. Know the rules and regulations of the area.
Take I-80 West to Exit 27A and continue south on U.S. Route 206 for 8.0 miles. Turn right onto County Route 513 and follow it for 1.2 miles to the entrance to Cooper Mill Park, on the left side of the road.
