Old Albany Post Road passes through heavily wooded and lightly populated country along the southeastern edge of the Hudson Highlands.
Houses, many on large lots, are the only development along the road, and there are no settlements along its length.
The countryside is rugged, with the road going up and down several hills.
Some areas are scenic, with meadows and views of the nearby hills and mountains.

It branches off to the northwest at the point where Gallows Hill Road becomes Sprout Brook Road.
From there it takes a west-northwestward, meandering course at first, narrowing almost to one lane at some points and climbing steadily to where the Catskill Aqueduct crosses, but soon bends to the north-northeast and widens.
It climbs and then descends over the next two miles (3 km) to the Lake Celeste area, where it becomes more northerly.
Then it bends to the northeast again, going up and down several hills through mostly undeveloped areas, to Chapman Road, where the Appalachian Trail crosses.

Out of that intersection it resumes its northward course, traversing around Fort Defiance Mountain, to Canopus Hill Road.
There it turns to the northwest.
At the corner of Travis Corners Road, a monument explains the historical importance of the road.
From here it runs almost straight north-northwest past some farms and more open land to cross Philipse Brook at the junction with Philipse Brook Road.

Beyond, the road remains mostly straight and northwestward, eventually returning to more wooded country along a ridgetop where the southwestern corner of Clarence Fahnestock State Park is nearby.
It then turns more to the west and descends to the intersection with Indian Brook Road, near the Bird and Bottle Inn.
From here it parallels nearby Route 9, reaching some more developed areas until it finally ends with a merge onto the highway.
