The 16th annual Boryeong Mud Festival, which kicked off this past weekend and will run until July 28, hopes to beat its record of 3 million participants last year.
Organizers say this year's mud bath is expected to attract 300,000 foreign tourists, up 22,000 from last year. Korean media have reported that trains to Boryeong are already packed with dirt-ready foreigners.
Call it the world's biggest mud fight or its largest group cosmetic treatment -- either way, millions of visitors are making their way to Boryeong, South Chungcheong Province this week for South Korea's most popular festival.
