Anyone who has ever visited Torrevieja will remember the surreal image of a pink water surface glistening in the sun. This unique natural phenomenon – officially known as Laguna Rosa – is located in the Las Lagunas de La Mata y Torrevieja Natural Park, together with the nearby Green Lagoon. The lake is not only a visual spectacle, but also a place where centuries-old salt extraction, special flora and fauna and a rare ecosystem come together.

The pink colour is created by halobacteria and the micro-algae *Dunaliella salina*, which produce pigments in this extremely salty water. This ensures an intense pink glow, especially in sunlight and when there is no wind. The salt concentration in the lake is between 300 and 350 grams per litre, comparable to the Dead Sea. The history of salt mining in this area dates back to the 13th century, but only really gained significance in the 19th century when Torrevieja developed into an important salt centre. Today, around 600,000 tonnes of salt are still produced here annually. The mud around the lake is also known for its healing properties.

What happens to that salt?
The salt extracted is partly used for consumption and food preservation, but the largest share goes to industry and road works. For example, a large part of the salt is exported to Northern and Central Europe, where it is used as road salt in the winter. In addition, chemical companies use it in water purification and the production of cleaning agents.

Nature lovers will also find what they are looking for here. Flamingos, waders and other water birds live around the lake, as well as saltwater fleas such as *Artemia salina*. Salt-loving plants such as *Salicornia* grow along the shores, and in spring you can even spot wild orchids.
