National Park System units within a drive of Cincinnati
Four National Park System units sit within an estimated two hours of Cincinnati, seven between two and four hours, and 43 between four and eight. The closest is William Howard Taft National Historic Site, about 5 minutes by road from the metro's Census centroid. Mammoth Cave National Park is the nearest unit carrying the National Park designation within four hours. The metro is the Cincinnati area as the Census Bureau defines it, home to 2,302,815 people in the 2024 estimates.
Each drive time is an estimate made from the straight-line distance between the metro's Census centroid and the unit's listed coordinates, multiplied by 1.25 for roads and divided by 55 mph, so a real trip will often take longer.
