Tourism Mer d'Iroise
The Iroise Sea is part of the Atlantic Ocean stretching from theisland of Sein to that of Ouessant.This sea is known because it is one of the most dangerous in Europe, it is typically driven by strong currents:the passage du Four, the Raz de Sein... Its many coral reefs and for the most emergent at low tide, make navigation difficult.Nevertheless it is also considered one of the richest in biodiversity, is what motivated its classification as a biosphere reserve by UNESCO in 1988. It was the first Marine Park in France in October 2007.
