Black Rock Mountain Loop from Reservoir Road Trailhead
Directions to trailhead
Address: 129 Continental Road, Cornwall, NY
From the south: Take the Palisades Interstate Parkway to its northern terminus at the Bear Mountain Circle and continue north on US 9W for 8.8 miles. About half a mile after passing a parking area marked with a blue sign, turn right onto Mountain Road. Immediately, turn right again and proceed through a very narrow underpass beneath US 9W (large vehicles may not fit). Continue ahead for 0.2 mile to a parking area for Black Rock Forest on the right.
From the kiosk just beyond the parking area, proceed ahead on the red-blazed Duggan Trail. In about half a mile, the red trail ends at a junction with the blue-blazed Reservoir Trail. Continue ahead on the blue trail, which crosses Ben's Bridge (a wooden footbridge) and climbs along a picturesque stream, with cascades and waterfalls, following an old woods road.
In about 0.4 mile, you’ll notice a pipeline crossing the stream on stone abutments. Then, in another 500 feet, a sign marks the start of the Honey Hill Trail. Turn right and follow this white-blazed trail, which continues to climb steadily. In a third of a mile, you’ll reach the crest of the rise, marked by a radio antenna on the right. The trail now begins to descend. A short distance ahead, a directional sign marks a broad viewpoint from a rock ledge to the right of the trail. Just ahead is Black Rock (which you will soon climb), and the Shawangunk Mountains are visible on the horizon to the northwest.
The Honey Hill Trail continues to descend. After a short switchback, it turns left onto a level footpath – the route of the pipeline that crossed the stream earlier in the hike. You’ll notice that rock walls have been provided to support sections of the pipeline.
The white-blazed Honey Hill Trail ends at a junction with the joint Stillman (yellow) and Highlands (teal diamond) Trails at the base of the Aleck Meadow Reservoir dam. Turn right onto the Stillman/Highlands Trail, which follows a woods road below the dam and, at the end of the reservoir, enters the woods on a footpath. Bear left at a junction with the white-blazed Black Rock Hollow Trail, then (in 300 feet) – with White Oak Road visible on the left - turn sharply right and climb to the summit of Black Rock Mountain (elevation 1,410 feet).
The summit affords a panoramic view, with Schunemunk Mountain and the Metro-North Railroad's Moodna Viaduct to the west, the Hudson River (crossed by the Newburgh-Beacon Bridge) to the northeast, and the Shawangunk Mountains on the northwest horizon. You'll want to take a break to rest from the climb and savor the view.
When you're ready to continue, turn left and descend steeply, continuing to follow the yellow and teal diamond blazes (do not follow the faded blue-and-yellow "footprint" blazes that head north across the summit). The grade soon moderates and, in about half a mile, you'll reach a wide gravel road.
Turn right and follow this road, known as Hulse Road, downhill. The road briefly climbs a little but then resumes a steady descent, rather steeply in places. Continue along this pleasant road for over a mile until it ends at a junction with the white-blazed Black Rock Hollow Trail. Route 9W is ahead, just across Black Rock Brook, so (unfortunately) you will hear the noise of traffic.
Turn right and follow the white-blazed trail along another gravel road, with Black Rock Brook to the left. You'll pass an old stone dam on the brook and some attractive cascades. Gradually, the road moves away from the brook and the trail, and the noise level decreases.
In half a mile, you'll reach a water filtration plant. Here, the Black Rock Hollow Trail turns right and starts to climb more steeply, but you should bear left, skirting the filtration plant, and continue on the blue-blazed Reservoir Trail.
A short distance ahead, you'll come to a junction where the Reservoir Trail turns right to cross Ben's Bridge. Do not cross the bridge or follow an unmarked trail on the left. Rather, turn very sharply left onto the red-blazed Duggan Trail and follow it back to the parking area where the hike began..
