Choansan is a low mountain in Wolgye-dong, Nowon-gu, Seoul, used for walks and light exercise. The trail starts beside Exit 2 of Wolgye Station and passes Nokcheonjeong and Choansan Sports Town before reaching the summit and descending toward Nokcheon Station. Stone statues of scholars remain around the tombs of Joseon-era eunuchs, and the whole of Choansan is designated as a cultural heritage area. The slope is gentle enough to climb in sneakers, and exercise facilities along the way make it a route for light walks.
