Ecorium is inside the National Institute of Ecology in Seocheon and displays ecosystems from tropical, desert, Mediterranean, temperate, and polar regions. It is close to the west gate behind Janghang Station, and exhibits include ants, desert cacti, fennec foxes, fish, birds of prey, and gibbons. Viewing can take four to six hours, and the walk from the parking lot by the west gate ticket office to Ecorium is easy. The shuttle bus at the main gate entrance has long wait times.
