Kentucky Route 1 allows access to Greenbo Lake State Resort Park and River Bend Golf Course, as well to the Oldtown Covered Bridge and the Jesse Stuart Nature Preserve. For general travel between Grayson and Greenup, Kentucky Route 67 is suggested over the much narrower and twisting Route 1.

Caney Falls, on the Little Fork of the Little Sandy, is to the south of Route 1, between Grayson and Route 3.
