Achasan Ridge

아차산

Gwangjin, Seoul · 서울

A low ridge on the eastern edge of the city with Goguryeo-era fortress remains along the top and a clear eastward view over the Han towards Guri.

Why it’s worth it

It is the sunrise hike locals actually do — short, lit at the bottom, and you can be back at Gwangnaru station for breakfast by eight.
