This old ritualistic tradition takes place on Ko Lanta during the full moon of the sixth and eleventh month in the lunar calendar. This is a religious rite performed by the sea gypsies of Ko Lanta, as well as, from other neighbouring areas, who gather on the beach near Sala Dan Village. They dance their famous "rong ngeng" round the boats of misfortune to be set adrift. Ceremonies feature singing and dancing. This festival is expected to bring prosperity and happiness to the participants.
