Driving Directions

Take the Taconic State Parkway to Route 202 and turn west. At the traffic light at Lexington Avenue, at 1.8 miles, turn right. Drive 0.6 mile to Morris Lane. Turn right and go into the parking lot at the bottom of the hill.


Sylvan Glen Nature Preserve is the site of a granite quarry that opened in 1895 and was abandoned in the fall of 1941 just before the advent of World War II. In its heyday, it employed hundreds of workers, and its high-quality stone was used to construct such landmarks as the Cathedral of St. John the Divine in Manhattan and the approaches to the George Washington Bridge. Operations at the quarry were terminated rather abruptly, with the result that much of the machinery was left behind and still may be seen today. The trails in this 408-acre park are blazed with colored plastic markers of the Town of Yorktown. 

From the kiosk at the end of the parking area, proceed ahead on the white-blazed Turtle Pond Trail, which follows a woods road, passing a pond to the right. After passing a fenced-in dog park on the left, the trail bears right, then turns left as it heads uphill.

At the top of the climb, three yellow blazes on a tree to the left mark the start of the Snake Hill Trail and almost immediately the end of the blue-blazed High Quarry Trail. Continue on the Turtle Pond Trail  which descends to cross a gas pipeline and reenters the woods on a footpath.

After reentering the woods, the Turtle Pond Trail passes through white pines and crosses Sylvan Brook. Foundations and remnants of quarrying operations and interpretive signs are along the trail. The trail turns, passes the High Quarry Trail (blue) to the left and turns right. At 1.1 miles, the trail turns left, passes the end of the Sylvan Glen Trail (red), and ascends. It turns left again and passes the now overgrown entrance to the High Quarry. 

When the Turtle Pond Trail ends at the High Quarry Trail, turn right and head steeply uphill. At the top, pieces of abandoned quarry machinery and cables are scattered along the trail. The trail goes under a rock bridge with more quarry equipment off to the left. It passes a water-filled quarry and then a stone shed that housed explosives. At 1.7 miles, take the side trail to a view into the quarry pit and to the west. Observe caution and stay back from the edge.

Leave the view and follow the co-aligned High Quarry (blue) and Sylvan Glen (red) trails away from the quarry operations. When the trails split, go straight on the Sylvan GlenTrail (red), which crosses wet areas and goes up and over a knoll. After going through several stone walls, it passes a large pond to the right.

At the junction with the Old Farm Trail (green) at 2.5 miles, turn left. To the right, the trail leads to parking on Stony Street. The Old Farm Trail heads uphill and passes an orange blazed trail to Quarry Drive (no parking). After going through a stone wall, it turns right onto the Ring Trail (yellow), an old riding ring. In about 100 feet, turn right to go through the stone wall a second time. The trail crosses a bridge over a large ditch dug in hopes of draining a wet area to the north. It passes the end of the Taconic Bridge Trail (pink) that heads to Granite Knolls Park and the bridge over the Taconic State Parkway.

After following a woods road, the Old Farm Trail ends at the High Quarry Trail at 3.0 miles. Turn left and follow the High Quarry Trail back to the quarry area and take the Sylvan Glen Trail (red) behind the pile of discarded rocks.

The Sylvan Glen Trail heads left uphill along a narrow path and turns around the end of the knob of the hill. It descends gradually at first and then turns to descend steeply. At 3.8 miles reach stone steps, built by the Jolly Rovers, a highly skilled group of Trail Conference volunteers who specialize in rock work. They spent 706 hours to build the 36 steps, moving 21 tons of stone in the process. A side trail at the bottom of the steps leads 200 feet to the 18-foot circumference Quarry Oak.

The Sylvan Glen Trail turns right, passes a large pile of discarded rocks, and enters the quarry. Large stones in the quarry floor are another place to have lunch or snack. The trail leaves the quarry and ends at the Turtle Pond Trail. These trails were built in 2010 by Trail Conference volunteers as part of the East Hudson Community Trails program in Yorktown. Go straight to follow the Turtle Pond Trail back to the parking lot for a 4.9-mile hike.

For a 3.1-mile hike, skip the loop after the visit the view to the High Quarry.

Where is it?

Very hard to figure out where this is based on the driving directions ... "Sylvan Glen Park" does not show up when doing a Google Maps search.  It would help to provide the name of the town where this is located with an intersection close to the park.  Don't mean to sound negative. The hike itself looks very interesting. 

In response to sfratini

You are right- the hike is very interesting. But enter at your own risk at the moment. The maps have yet to be updated at the entrance, there are currently 2 red trails, yet one is NOT marked on the map. Neither have the Green, Orange, Yellow and Red #2 trails been added to the map. If you stick to the White trail to Blue Trail- that is a 1 hour hike that takes you up to and through the Quarry. The park is in Yorktown, NY at the end of Morris Lane, off of Lexington Avenue.  As for bringing your dogs, the rules posted at the entrance are somewhat confusing. One sign says "No Dogs", while another is asking you to "leash your pets." This is a great place to bring your dog and many, many people do. Please be a responsible dog owner though and clean up after your dog, otherwise it will ruin it for those who enjoy being able to explore the woods with our favorite four-legged companions.
