 KY 70 from the Mammoth Cave park's southeast boundary to the junction with KY 90 is part of the Cordell Hill Scenic Byway, most of which is the core route of the annual Roller Coaster Yard Sale, which includes parts of KY 90 and KY 63 in the southern part of the state.After departing Cave City, KY 70 eventually crosses US Route 31E, and heads for Hiseville, and then crosses into the northern part of Metcalfe County.Once it crosses into Metcalfe County, it will go through Sulphur Well.
