With the city of Seoul alone boasting 37 mountains, you can easily imagine what Korea's terrain is like. There are more than 800 mountains in Korea, with each one of them offering their own special highlights. One of the local favorites is the impressive Seoraksan Mountain (설악산) during Autumn. Countless numbers of people venture out to view the autumn foliage. If you aren't up for hiking, there is a cable car that will lift you up 670 meters to Gwongeumseong Fortress (권금성) in about 5 minutes. The mountains within Seoul offer quite remarkable views of the city scape, and are easily accessible by bus and/or subway.
