Of all the islands in the Balearic archipelago, Ibiza is the third largest. It lies in the west of the Mediterranean Sea, and enjoys a surface area of around 572 square kilometres, with 200km of coast. The island is home to some of the biggest, and most expensive nightclubs in the world, and so is perhaps most widely known for its party tourism. Thousands come from the world over just to enjoy these clubs, the availability of drugs, and nurse their hangovers on the beautiful coastline.
