Cox Arboretum, located in Dayton, Ohio, is part of the Five Rivers Metropark. It was founded in 1962, when the Cox family donated their property to create an arboretum.
Cox Arboretum covers 160 acres, and features 19 gardens. These include a water garden, rock garden, clematis arbor, a children's maze, conifer collection, and an Edible Landscape garden, which in the spring is especially pretty with its blooms of tulips, hyacinths, and daffodils.
For those who like to hike, there are plenty of trails. You may want to bring a lunch and picnic in one of the pretty gazebos. If you're lucky, you might get to meet Zipp, the working Border Collie, who works diligently to chase away the Canadian geese.
The arboretum is open daily from 8 AM to 8 PM. Admission is free.
