This wild and lovely park stretching from Madison Valley up to Union Bay offers a wide variety of gardens, a wetlands nature trail and 200 acres of mature forest threaded by paths. More than 5500 plant species grow within the arboretum’s boundaries. In the spring Azalea Way, a meandering trail that winds through the arboretum, is lined with a giddy array of pink- and orange-flowered azaleas and rhododendrons.
Trail guides to the plant collections are available at the Graham Visitors Center. Free guided tours of the grounds take place at 1pm on Sundays from January to November.
