The Pelagos Sanctuary for Mediterranean Marine Mammals. This sanctuary came about in 1999 as a result of a collaboration between France (Cote d’Azur and Corsica), Monaco and Italy (Liguria, Tuscany and Northern Sardinia). The area was included in the list of special protected zones under the Barcelona Convention and, as such, recognised by all countries of the Mediterranean area. These waters cover some 100,000 km² and are distinguished by particular environmental characteristics which provide nutrition to the various species of marine mammals that live there.

Considering the number of cetaceans in the Ligurian Sea, safeguarding their habitat is of fundamental importance and the adjacent land and sea areas are considered protected areas where boats, fishing and tourism activities that may damage or disturb the mammals are regulated by law.

Excursions take place between May and September and are usually conducted under the supervision of a researcher collecting data on the sightings made during the excursions.
