This hike loops around a lake, formerly known as the Haledon Reservoir, which once served as the water supply for Haledon, North Haledon and Prospect Park. The 75-acre lake and the surrounding land was acquired by the Borough of Franklin Lakes in 2006 and is now known as the G. Thomas Donch Nature Preserve.
From the parking area, climb up the road leading to the dam, passing to the left of the locked gate. When you reach the top of the dam, you’ll notice (on the fence on the left) a triple white blaze that marks the start of the Preserve Shoreline Loop Trail. You’ll be following this white-blazed trail around the lake.
Turn left and cross the dam, with views of the lake to the right and of the Lower Pond to the left. At the end of the dam, turn right and follow a narrow dirt path between a chain-link fence (with High Mountain Road beyond) on the left and the lake on the right. Several short side trails on the right lead to viewpoints over the lake, and benches have been provided for those who wish to rest while admiring the views. Soon, you’ll reach an opening in the fence where the Red Trail to High Mountain Park Preserve begins on the left. The white-blazed trail now crosses an open grassy expanse and enters a wooded area.
After crossing a wooden footbridge over a culvert, the trail reaches the intersection of High Mountain Road and Ewing Avenue. Here, it bears right and begins to parallel Ewing Avenue. The trail crosses an inlet of the lake on another wooden footbridge and continues beneath tall evergreen trees.
Upon reaching the intersection with Waterview Drive, go through an opening in the fence on the left and use the road bridge to cross the outlet of a wetland to the northwest. At the end of the chain-link fence, turn right and reenter the preserve (just beyond a large sign for the G. Thomas Donch Nature Preserve).
Just ahead, a signpost marks the start of the blue-blazed Island Bridges Trail. Turn right and fo
llow this trail along a dike that juts into the lake, forming a lagoon on the left. Short paths lead out to the water on both sides of the trail, and there are fine views of High Mountain to the right (southwest). Along the way, the trail crosses two floating pontoon bridges over gaps in the dike.
Just past the second bridge, you’ll notice an open area on the shoreline across the lagoon to the left. This feature, known as Basalt Beach, is a large expanse of basalt rock (characteristic of the Watchung range). In another 500 feet, as the trail bears left, an expanse of basalt rock may be seen just to the right of the trail.
Soon, you’ll reach the end of the Island Bridges Trail at a junction with the Preserve Shoreline Loop Trail, marked by several jagged basalt boulders on the right. Turn right and follow the white-blazed Shoreline Loop Trail along a wide dirt-and-gravel woods road. After a while, you’ll pass homes on the left. Just beyond, you’ll notice a sign on the right for an Accessible Trail. The wide path on the right is a “lollipop”-loop trail that leads to a viewpoint over the lake. You can take this loop if you want to lengthen your hike a little.
Just ahead on the woods road, as you come to a pine grove, you’ll notice a continuation of the Accessible Trail on the right. You can either continue ahead on the road (the official route of the Preserve Shoreline Loop Trail) or follow the Accessible Trail, which winds through the pine forest and crosses a wetland on a pontoon bridge. Either way, you’ll reach the kiosk adjacent to the parking area where the hike began, completing the loop.

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 N.J. Route 208 to the Ewing Avenue exit in Franklin Lakes. Turn left at the end of the ramp (if coming from the west, turn right) and continue for about two miles until Ewing Avenue ends at High Mountain Road. Turn left onto High Mountain Road and continue past a lake and a smaller pond on the left. In 0.5 mile, at the end of the smaller pond, you will see a small brown sign for the G. Thomas Donch Nature Preserve on the left. Turn left into a driveway, passing old reservoir buildings on the right, drive across the dam of the Lower Pond, then turn left again at a sign for parking and continue to a parking area just below the dam of the Upper Lake. GPS address: 1196 High Mountain Road, North Haledon, N.J. 07508. NOTE: As of May 2024, the driveway leading into the Preserve is closed for repairs. After turning onto High Mountain Road, hikers should proceed past Temple Emanuel and the Vander Platt-Vermuelen Memorial Home and turn right onto Reservoir Drive. Park along Reservoir Drive and walk back to High Mountain Road. At the crosswalk provided, cross the road, go through the gap in the fence, and turn left to continue on the trail around the reservoir.
