High Falls is a hamlet (and census-designated place) in Ulster County, New York, United States.

The first bridge to nearby Stone Ridge, on the main road through the valley between the Shawangunks and Catskills, was built during this time.

The stone Jacob DePuy House, from 1797 (expanded in mid-19th century), reflects this era and retains much of its original fabric.

In the early 19th century, a cotton and woolen factory in the hamlet made it a center of local manufacturing, serving many of the farms in the surrounding area.

The D & H was built to transport anthracite coal from Northeastern Pennsylvania to New York City via Kingston, where it was transferred to ships plying the Hudson River.

The road extending down from the Shawangunks had made High Falls a point of embarkation via carriage for canal or rail travelers destined for Mohonk Mountain House atop the ridge.
