Jeju National Museum, Jeju

Don't associate the name of the National Museum with the great museum in Seoul. It is a museum of the scale suitable for the place named Jeju Island. The building is well maintained and the exhibits are relaxed. It is a part of the national policy as well as the museum in Seoul that can be seen for free. It is possible to get there by bus, but it may be more convenient to take a cheap taxi than in Japan. If you are interested in history, you might want to take a look around the exhibits slowly, but if you're not too bright in history, you might end up looking at them in about 30 minutes. I didn't find any other place to kill time, so I might say it's appropriate to visit without too much expectation.
