North of Red Creek, NY 104A continues on a northerly alignment for another , roughly paralleling the nearby Wayne–Cayuga county line. At the end of this north–south stretch, the route curves to the northeast to enter Cayuga County and the town of Sterling. Just inside the county line is the small village of Fair Haven, where NY 104A passes Little Sodus Bay and the surrounding Fair Haven Beach State Park. While in the village, it crosses the Cato–Fair Haven Trail, a foot trail linking Fair Haven to the village of Cato to the southeast. East of the village, it continues on a generally linear routing across farmland to a junction with the northern terminus of NY 38. At this point, NY 104A turns back to the north, following the right-of-way of NY 38 to the hamlet of Sterling.
