A 50-acre wonderland of history and exploration in rural northwest Tennessee is the best way to describe Discovery Park, the brainchild of a local philanthropist. Located in Union City - the county seat of the agricultural Obion County - Discovery Park features indoor and outdoor exhibits and areas to explore, including natural history and regional museum areas, scientific and transportation areas, and pioneer and agricultural areas. Uniting everything about the Discovery Park is one thing - hands-on exploration. 50,000 square feet of exhibits inside and 50 acres of park-like grounds outside provide literally hours of exploration - for kids and adults alike. The park is closed on Mondays with the exception of Memorial Day, Labor Day and the Fourth of July.
