Located along the Hangang River, Seoul has grown into a teeming metropolis with a population of more than 10 million. Over the years, the capital city of Korea has greatly expanded in the process of urbanization and industrialization and continues to grow as the thriving center of the country's political, economic, cultural and educational activities.

Seoul is the world's 10th-largest city. Its past and present coexist in a fascinating way: centuries-old palaces, city gates, shrines, gardens and priceless art collections attest to the city's illustrious past, while the glistening facades of soaring skyscrapers and the bustling traffic represent its vibrant present.

The old city was encircled by four inner mountains and four outer mountains. Bugaksan in the north, Naksan in the east, Inwangsan in the west, and Namsan in the south are "the inner mountains" as all were originally inside the old city walls of the Joseon capital. The four outer mountains are Bukhansan in the north, Yongmasan in the east, Deogyangsan in the west, and Gwanaksan in the south. Each mountain has a unique beauty of its own while boasting natural scenic landscapes and spectacular views overlooking the city of Seoul. There are also numerous mountain springs that freely provide clean, clear water to refresh weary hikers.

In Seoul, the must-see attractions are the ancient royal palaces of the Joseon Dynasty: Gyeongbokgung, Deoksugung, Changdeokgung, and Changgyeonggung. Jongmyo, the royal ancestral shrine of the Joseon Dynasty, and Changdeokgung's adjacent Huwon (Rear Garden also known as the Secret Garden) are noted for their beautifully landscaped gardens and classical structures.
