Daegu Arboretum is located at the site of an old sanitary landfill. The restoration of the area passed through many stages from 1996 until the opening in May 2002. It is home to more than thousands of species of plants including giant cacti, flowers, medicinal herbs, and trees in 21 gardens. The arboretum serves as an ecological education center and rest area for Daegu citizens. Ecology experience programs for students and young children are held regularly during summer vacation. Nearby attractions include Apsan and Duryu Parks, as well as Palgongsan and Biseulsan Mountains.
