The Fiestas of San Juan have long been a popular festival in June throughout the World and many regions of Spain. It has long been a tradition to celebrate the arrival of Summer in which most towns in Spain celebrate this yearly party.
The Fiestas see bonfires lit in towns and along beaches, some just enjoy the fire and in some towns it is known to jump over the fires. Food and drink vary region to region although you are likely to come across Jamon (Serrano Ham) at some point!
