Korea Expressway Corporation Arboretum (Jeonju Arboretum) is located in a relatively warm region of the country, reaching 20-30 meters in altitude. Operated by Korea Expressway Corporation, the garden is a non-profit aboretum that is free and open to the public. The garden was built to restore the local environment that was damaged during the construction of an expressway in 1972, starting with a nursery field. The builders then began collecting plants in 1983, and eventually opened the garden in 1992. The arboretum now sees an average of 200,000 visitors per year.
The garden operates various hands-on programs and summer educational programs due to its diverse plant species.
