The route heads northeast through the heavily forested area as a two-lane road, passing a small number of isolated houses along the way.

It intersects with County Route 7 (CR 7 or Macomb Road) before entering a stretch with several farms ahead of the De Peyster town line.

About 2.5 miles (4.0 km) into De Peyster, the route crosses over Fish Creek and briefly traverses a marshy area surrounding the waterway.

Past the stream, NY 184 curves northward for roughly 1.5 miles (2.4 km) prior to taking a more pronounced northeasterly track toward the town of Oswegatchie.

[4] Near the De Peyster–Oswegatchie town line, the route begins to parallel the south bank of the Oswegatchie River as it merges with the alignment of CR 10 (Old State Road).
