The highway heads southeast from the junction, running along the northeastern edge of Lake Tiorati as it passes by the dense forests that comprise most of Harriman State Park.

[1] After 1 mile (1.6 km), the highway serves the Tiorati Workshop, a collaboration between the State Park and Bank Street College of Education, located adjacent to the eastern lake shore.

[2] Past the workshop, the road takes on a more southerly routing and descends down a hill before crossing Tiorati Brook by way of a dam.

Just south of the dam is Day Camp in the Park, where Tiorati Brook Road turns back to the east to follow its namesake waterway away from the lake.

[4] In May 1915, the Palisades Interstate Park Commission took over maintenance of the road, which ran from the dam at Cedar Ponds to the village of Stony Point.
