Do you need to re-energize yourself? Why not venture out to one of Korea's spectacular forests? Phytoncide, the organic compound derived from plants is known to help in relieving stress and restoring energy. You are sure to feel better after a day in the forest, soaking up all the fresh air and phytoncide. Admission fees for the recreational forests are nominal, about 1000 won. If you wish stay overnight, many parks also have wooden cabins available for rental and campsites as well. They are in high demand, so be sure to reserve a month in advance. For an experience within the city of Seoul, try one of the many mountains located within the city such as Mt. Inwangsan (인왕산) or Mt. Dobongsan (도봉산).
