Fodor's Expert Review Bukhansan National Park

Only a short subway ride from central Seoul, Bukhansan is both the tallest and most beautiful of the city's many easily accessible mountains. The mountain and the surrounding 30-square-mile Bukhansan National Park is an ecological island in the city. In addition to fresh air, views of the city, and more than 1,300 species of plants and animals, Bukhansan is home to numerous historical and cultural sights. Of note are the Bukhansanseong Fortress and more than 100 temples scattered throughout the area. Hikers looking for solitude, however, are in for a disappointment. It is full of other hikers year-round and is listed in Guinness Book of World Records as the "Most Visited National Park per Unit Area."
