These shots were taken at the Unification Observatory atop Odusan. On an express bus, the trip takes about 45 minutes one way from Shinchon or Gwanghwamun. The observatory boasts very clear views of North Korea, which at this section of the border, is right across the river. It’s a good idea to stop by the nearby artist colony of Haeiri on the same trip as the area is like nothing you’ve probably experienced in Korea before: big houses with yards, low population density, non-apartment-type residences etc.
