Moulon: boat arch-and-wall dive on the Côte Bleue
Moulon: boat arch-and-wall dive on the Côte Bleue
The normal setup is a guided boat dive from a Côte Bleue operator.
Moulon is a boat dive on the Côte Bleue between Méjean and Niolon, centered on a limestone arch, a coralligenous wall, and a deeper tombant. The reef and its blocks hold sars, loups, mostelles, and langoustes, with gorgonians making the route feel slow, scenic, and very Mediterranean. It is better treated as a guided, current-aware dive than as casual sightseeing, because the site can turn technical when the flow picks up.
