Italy's Costa Smeralda (Emerald Coast) is one of the most beloved and appreciated tourist destinations in Sardinia and all of Italy. The reason is simple: here, you’ll find some of the most beautiful beaches in Europe and the sea is crystal clear. Moreover, in the various towns along the coast, there are plenty of things to do and see, with numerous events and festivals organised every day. But have you ever wondered where the name "Emerald Coast" came from? We'll give you a clue - it has nothing to do with the colour of the sea. 

It would certainly be logical to think that the name Costa Smeralda refers to its crystal-clear waters that have an emerald tinge. However, the origin of the name is quite different. It is said to come from an idea by Giuseppe Mentasti, the owner of Acqua San Pellegrino and the island of Mortorio.
