Wando Arboretum features the largest and oldest broadleaf evergreen colony in the nation, along with over 3,800 other flora on a grand plot of land. The arboretum is comprised of an exhibition hall, greenhouses, walking paths, an observatory, campground, basketball court, and more.

Created in 1991, Wando Arboretum is the only warm temperate arboretum in Korea where only 15% of the landscape is considered a warm temperate region. The broadleaf evergreen tree forest has high medicinal value, and is home to many species of rare warm temperate plants such as goodyera, calanthe striata, and cephalanthera falcata. There are 30 special gardens based on different plant types. From the observatory, visitors can enjoy the view of Dadohaehaesang National Park and the southern sea. The observatory offers an opportunity to educate visitors on nature and the environment and allows them to take a rest during their visit.
