The Iles Chausey archipelago ( 16 km off Granville) has an exceptional tidal range. The landscape can change very quickly. It is a well preserved place with areas accessible only at low tide which allows the birds to rest. The interior of the island also has a hedgerow area allowing migrating passerines to rest. Red-breasted Merganser nests here as well as in certain years the very rare Roseate Tern. On your way to the main island Chausey you can easily observe dolphins and many seabirds like Northern Gannet, Common Eider and Atlantic Puffin.


Français: Archipel granitique à 16 km au large de Granville, avec un marnage exceptionnel, le paysage change très rapidement. C'est un lieu préservé avec des zones accessibles uniquement à marée basse ce qui permet le repos des oiseaux. L'interieur de l'ile posséde aussi une zone de bocage permettant aux passereaux en migration de se reposer. Le harle huppé niche également ici ainsi que certaine année la sterne de Dougall. Dès le trajet en mer vous observez facilement dauphins, fou de bassant, eider, puffin.



The easiest way is to park at the Granville ferry terminal (Rue des isles 50400 GRANVILLE) and take a boat to go to the island (there are no cars on the island, everything is pedestrian). Once on the island you can walk on the paths. In one day a tour of the island is very easily done. For more info on the ferry, see the weblinks below.
