This lovely spot provides a home to the Cincinnati Flower Show each year.. In Short Cincinnati is known as a city of parks, and Ault is its fourth largest at nearly 224 acres. The park's popularity reaches a peak each spring during the annual flower show, but nearby Hyde Parkers frequent it throughout the year. Top attractions include the pavilion, lookout point and formal gardens. There's an outstanding collection of roses and a grove of trees chosen specifically for their ability to grow in the Cincinnati area.
