Isla de sa Porrassa
Isla de sa Porassa is located in the bay of the village of Magaluf, Majorca, Spain.
Measuring over across at its widest point, the island is a feature at the heart of Magaluf Bay. It is above sea level. The island is uninhabited, but visited during the summer season by many holidaymakers, either swimming or on personal water craft from Magaluf Beach.
Since 2014, British holidaymakers have unofficially dubbed the rock "Big Swillers Island" due to it being seen as a rite of passage for young party-goers to try to reach the island whilst intoxicated. However local police have advised against this due to the risk it entails.
