Washington Park Arboretum
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.
