Iljasan is a 134-metre hiking course that spans Dunchon-dong in Seoul's Gangdong-gu and Hanam in Gyeonggi-do. A circular trail runs along the summit, and the ridge is gentle, making for an easy walk. To the north are Herb Astronomy Park, Gangdong Greenway Family Camping Site, and Gildong Ecological Park, while to the south is the Gambuk-dong park cemetery. Walking the path, you pass exercise facilities and hear birdsong.
