A connected ridge hike across two peaks — Yongmasan (348m) and Achasan (295m) — offering panoramic views of the Han River and central Seoul that rival more famous mountains in the city. The full traverse covers 12.6km passing Goguryo-era fortress ruins at Achasanseong along the way. Trails are well-maintained and beginner-friendly with clear English signage, yet rarely crowded with tourists.
