The island of Sardinia in Italy, with its rugged cliffs, secret beaches and endless shades of blue, is undeniably a Mediterranean treasure.

This island has a coastline that stretches over 1,700 kilometres.

While natural rivers are few, with Tirso being the longest, Sardinia has embraced innovation with 54 artificial lakes and dams.

Among the most significant are Lake Omodeo and Lake Coghinas, key sources of water and electricity for the region.
