According to the United States Census Bureau, the town has a total area of 23.0 square miles (60 km), all of it land.
Halcott is in the Catskill Mountains. The west and south town lines are the border of Delaware County. The northern and eastern borders are the range of mountains from Bearpen Mountain to Halcott Mountain, beyond which lies the neighboring town of Lexington. The town of Halcott is basically the valley of Vly Creek, and ringed by mountains on three sides. Most access to the town is from the south, via the Delaware County village of Fleischmanns.
The pass between Bearpen and neighboring Vly Mountain is traversed by Halcott Mountain Road, an unimproved county highway which reaches 2,800 feet (850 m) at the col, making it the highest elevation free public through road in New York State. It is also the only route between Halcott and the rest of Greene County. Like Hardenburgh in nearby Ulster County, to reach the rest of the county via a paved road one must leave and go through a portion of either Ulster or Delaware counties.
Due to this geographic isolation, Halcott is the only place in Greene County whose telephones are in the 845 area code.
