The route proceeds southeastward as a two-lane highway, winding its way past a handful of homes built on the side of a valley surrounding the lake.

The residential surroundings begin to taper off at the top of the valley's edge, where NY 423 meets the south end of County Route 70 (CR 70).

From here, the highway turns slightly eastward, passing through a wooded, marshy area surrounding a small creek.

[4] Past the marsh, NY 423 leaves the woods for a 2-mile (3.2 km) stretch of mostly open fields and a small number of isolated homes.

[5] The road between Saratoga Lake and the historic site was taken over by the state of New York in the early 1920s,[6][7] and the two intersections with modern CR 70 were reduced to a single junction by 1929 after a new direct connection was built between the two formerly separate east–west segments.
