Busan Green Railway is a park that follows the coastal path between Mipo and Cheongsapo. The walking route looks out over the sea and takes in an electric train, haesong pines and the sunset. The Mipo–Cheongsapo section is currently under construction, so the pedestrian path after the Dalmaji Tunnel is closed and a detour is required. Detour signage is sparse, which makes the route inconvenient to follow.
