North of New City, CR 33 serves as an alternative route for the US 9W/US 202 multiplex in northern Rockland County.
[2] CR 33 runs through Pearl River, Nanuet, New City, Garnerville, and Stony Point.
Unlike most of the county routes in Rockland, CR 33 runs through many business areas.
Here CR 33 is still named Middletown Road, but it is also considered Main Street within the business district of Nanuet.
After this intersection, CR 33 proceeds north into residential areas of Nanuet running parallel to NY 304.
CR 33 continues north through New City for another 2.6 miles (4.2 km) before beginning its trek through Hi-Tor State Park.
CR 33 then proceeds into the town of Stony Point for the final mile and a half of its run.
It really would be impossible to extend CR 33 further north as Bear Mountain State Park lies close to its northern terminus.
