If you are tired of the city trip in Seoul, I would like to recommend you to visit any mountains in Korea. Almost 70% of the lands in South Korea are mounts and mountains.

The national parks which have the shelters are: Seoraksan, Sobaeksan, Jirisan, Deogyusan. Most trekking routes are blocked to avoid the prevalent fire accidents in the spring time. I planned to do the 3 days trekking in Jirisan, but the route was also blocked until May. Therefore, I had to decide to go to the Sobaeksan which is not that far from Seoul. The name Sobaek means small-white. It must be very beautiful in Winter time. The top of the Sobaek mountain, 1439m.
