Boryeong, commonly known as Daecheon, is a city in South Chungcheong Province, South Korea. It is located on the coast of the Yellow Sea. It lies on the Janghang Line railroad, which connects it to Seoul via the Gyeongbu Line. It is also connected to the Seohaean Expressway. Boryeong is known around Korea for its beaches, particularly Daecheon Beach, and its annual mud festival around July, Boryeong Mud Festival. The city's beach-mud is widely touted for its cosmetic properties. As elsewhere along the southwest coast of the Korean peninsula, there are numerous small islands, many of which are connected by ferry to Daecheon Port.
