Haspin Acres
Though not technically one of the ATV parks in Ohio since it’s located in Indiana, Haspin Acres is an honorable mention on this list because it’s near both Cincinnati and Dayton, and is popular among Ohio 4-wheeler riders.
The scenic 750-acre tract of woods and hills includes ATV and UTV riding trails with river crossings, hill climbs, and more. Additionally, there’s a 300-foot loose dirt drag strip, a pair of mud bogs, and a new UTV racetrack. Most of your exploring will be on unmarked trails except for occasional directional arrows.
