The nature reserve of Scandola located along the Corse west coast is listed as a world heritage area by UNESCO. It is also a 4124 acres national natural reserve managed by the Corsican Regional Natural Park. It is first, with the Porto gulf, a stunning geological place where we can discover traces of the 250 million years volcano whose caldera collapsed. Further it's also a place of interest for its rich biodiversity undersea as well as on earth. Today the place is under pressure with tourism and it is not a good idea to visit it on July or August. It is too busy and it seems that the tourism boating activity is most of the time completely discordant with sustainable development. Rules are absent or not abided by 90% of local operators that do exactly what they want putting under pressure the area and in the same time the visitors that come and pay to be there. I am not sure that tenths of small boats with sometimes 1000 horsepower outboards engines for twelve passengers is a good choice especially when the 300 meters off shore speed limit is never respected or when the local coastal harbors are entered at speed exceeding the 5 knots limit. This causes smoke, noise, waves at an uninterrupted frequency during whole day.
