Ornithology Ecrehous

The Maîtresse-Île is the largest of the islands of the Ecréhous archipelago. It is above all an ornithological reserve of 300 meters long and 150 meters wide, on which are the ruins of a monastic chapel of the XIIIth century. Mammalogists - or even the most experienced - will be able to observe the presence of the famous grey seal. On the east side of the island, a marine pit serves as a refuge for sailors and can accommodate some boats.
