South Korea is situated in the southern part of the Korean Peninsula, nestled between the Yellow Sea and the East Sea. It is a mountainous enclave where ancient tranquility intertwines with intense urbanism. Its capital, Seoul, is a modern metropolis featuring countless skyscrapers while preserving the historic Gyeongbokgung Palace. The often overlooked city of Gyeongju possesses an undeniable golden heritage of the Silla Kingdom, revealed through silent stone pagodas and royal burial mounds. For a volcanic retreat, Jeju Island offers a surreal landscape of basalt pillars and the emerald slopes of Hallasan.
