The Morton Arboretum is an outdoor museum of woody plants established in 1922 by Morton Salt magnate, Joy Morton. Situated on the rolling Valparaiso Moraine in northern Illinois and bisected by the DuPage River, the grounds encompass 1,700 acres of magnificent natural systems. There’s a restored 100-acre prairie, oak and black walnut woodlands, savannas, winding streams, lakes and marshes—and all of it is accessible on nine miles of paved one-way roads and 14 miles of hiking trails.
