HALLE RAVINE

Pound Ridge, Westchester County, NY


Directions:

Take I-684 north about 25 miles to exit 4. Go east (right) on Route 172 for 1.8 miles then northeast (left) on Route 22 for 1.2 miles, then east (right) on Pound Ridge Road for 4 miles. Go north (left) on Route 124 about 0.5 mile; turn northeast (right) onto Trinity Pass. Go 0.7 mile; the preserve is on the right, just before the intersection with Donbrook Road. Look for a white fence and gate.


History:

At the turn of the century the property was part of the Scofield Farm, but in 1928 it was bought by Hiram Halle, a local conservationist. These two ponds were built in the 1930s, presumably for enhancing wildlife use of the area. The unnamed stream that flows through the grounds descends about 100 feet from here through the winding 1/3-mile-long gorge. The trail crosses and re-crosses the stream several times.


Trail:

Halle Ravine is only 38 acres, but it is an interesting hemlock gorge. The trail follows a narrow stream that winds its way down from two ponds through hemlock trees to a more open area. Continuing one comes to a field.  Then you have to turn around and go back the way you came.
