Heading north from NY 31, NY 260, named Sweden–Walker Road for the two communities it connects, proceeds to the north-northeast as a two-lane highway through a lightly developed area of the town of Sweden, crossing both the former right-of-way of an old Conrail line known as the Falls Road Secondary and the Erie Canal before entering the town of Clarkson.

Continuing on its north-northeasterly path, NY 260 passes through areas of increasingly rural nature as it progresses through northern Clarkson.

Outside of Walker, NY 260 traverses large areas of farmland as it continues toward and eventually ends at the Lake Ontario State Parkway.

[5][6] This extension, as well as the piece of NY 260 added c. 1931, was initially maintained by Monroe County as the unsigned CR 230, a route that continued north of the parkway to the lake along Walker–Lake Ontario Road.

CR 230, meanwhile, no longer exists in any form as the remainder of the route north to the lakeshore was transferred to the town of Hamlin by March 2009.
