The "Haeundae Beach" is at the southeast end of the city of Busan which is in South Korea. Along the 12 km of coastline is Busan's most popular beach, and one of the most famous beaches in South Korea. "Haeundae" was so named by scholar Choi Chi-Won (857~?) of the Silla Dynasty (BC 57~AD 935). When he was walking past Dongbaekdo Island, he was fascinated by it and carved the words "Hae Un Dae" on a stone wall on the island. Haeundae is 1.5 km long, 30~50m wide, and spans an area of 58,400㎡. The white sand is rough and is rather sticky. The sand of this beach is composed of sand that comes from Chuncheon Stream and shells that have been naturally eroded by the wind over time.
