Inwangsan Shelter in the woods

Inwangsan Supsok Switeo is a public library reached by walking down the Inwangsan Fortress Trail toward Jahamun. It is a wooden building converted from an old military guard post, with floor-to-ceiling glass looking out onto the forest, and it is not a cafe that sells drinks. Books can be borrowed and read for free. Reaching it requires climbing steep stairs for 5 to 10 minutes from Chosobang.
