Wolmi Sea Train Wolmi Sea Station sits near Incheon Station. It is a sightseeing monorail that loops around Wolmi Island, with views of the sea, the harbor, and grain silos through the windows. The 6.1km course circles four stations and takes about 40 minutes, and passengers can get off at an intermediate station and ride once more. The train has two cars, so when it is crowded and no seats are available, passengers must stand.
