Boryeong Mud Festival in Boryeong
Boryeong's Daecheon Beach fills with mineral-rich mud every July, drawing crowds for mud wrestling, mud slides, obstacle courses, and beachside concerts. What began in 1998 as a promotional stunt for local mud cosmetics turned into one of Korea's best-known summer festivals, known for its foreigner-friendly atmosphere and the simple joy of getting filthy on a beach with strangers, then rinsing off in the sea.
Daecheon Beach turns brown every summer when Boryeong pumps in tons of mineral-rich mud from its tidal flats and lets visitors wallow in it.
