South Korea: DMZ – Peace Skyway
You can actually take a cable car ride over the Imjin River and loser to 2km Korean DMZ zone. This used to be a U.S. military base, but the Americans gave it back to the Koreans, who made an attraction and a museum out of it. As you ride in the gondola, you get great views of the rice fields (DMZ took some super fertile riverbank ground), and the Unification bridge. There is a museum on the other side of the river that displays a copy of the Armistice Agreement. Lots of “mine” signs on the fences.
