Best time to visit Great Seal State Park

Late spring through early fall, roughly May to October, is the most comfortable window for RV travel, with long daylight hours and dry trails for hiking and riding. October is a highlight, when the hardwood ridges turn brilliant gold, orange, and red. Summer weekends can be humid and buggy, so shoulder months of May, September, and early October offer cooler temperatures and lighter crowds. Winter visits are possible but trails are often muddy or icy and campground amenities are limited.

How to get to Great Seal State Park

The park sits just northeast of Chillicothe, Ohio, with the main entrance reached via Marietta Road and Rocky Road off U.S. Route 23. Columbus is about 55 miles north, roughly a 1 hour drive on U.S. 23, while Cincinnati is about 95 miles southwest and Dayton about 90 miles west, each around a 2 hour drive. Roads inside the park are narrow, hilly, and can have tight turns and steep grades, so larger motorhomes and long trailers should approach slowly and scout turnarounds before committing. The closest major airport for fly-and-rent trips is John Glenn Columbus International Airport (CMH).
