South Korea is an East Asian country that has built one of the world's most dynamic modern cultures on a foundation of Confucian philosophy, Buddhist heritage, and extraordinarily rapid development. Seoul is a city of remarkable energy, design, and food, while the temple stays, coastal islands, and mountain national parks of the wider country offer a quieter counterbalance. Those who love cities, food, and the particular intensity of Korean creative culture will find it endlessly stimulating.
