The Harbour of la Vanlée
Situated in the south-west of the department, between Agon-Coutainville and Granville, is an estuary where the river Vanlée flows. The harbour’s particularity is an immense “tongue” of sand, stretching to the North; its end is named “the end of the world”. The harbour of la Vanlée is an arm of sea – turning Saint-Martin-de-Bréhal into a peninsula – and consists of salt marshes, where sheep like to graze when the sea is out. But when the tide range is at its maximum, the sea floods the submersible road.
The harbour of Blainville
Just off Blainville-sur-Mer, behind a strip of coastal dunes, the silted harbour has been partly converted for agricultural activities, oyster farming and tourism purposes.
The harbour of Regnéville
In Regnéville-sur-Mer, the river Sienne flows into the Channel; its estuary, where fresh and sea water meet, covers almost 900 hectares, between the headlands of Agon and Montmartin-sur-Mer. Brent geese, oystercatchers and Kentish plovers enjoy this environment where they come to winter and nest in the spring.
The harbour of Geffosses
The harbour of Geffosses is a reserve of 185 hectares which spreads onto the communes of Geffosses and Anneville-sur-Mer. The site is a migratory stop-over location, and a wintering and breeding site for many birds and waders.
The harbour of Surville
The dunes spread deep into the land here, and are relatively well preserved from urbanisation and agriculture. The site is characterised by a dense network of watering “ponds”, ideal for the breeding of amphibians. It is in the vicinity of such a pond that a cluster of Fen orchid was found; this species of orchid is particularly rare and was thought to have completely disappeared in Lower-Normandy.
The harbour of Saint-Germain-Sur-Ay
It is the largest harbour on the West coast of Cotentin (600 ha), delimited to the north by the “Pointe du Banc” in St Germain sur Ay, and to the south by the dunes of Créances.
Constituted of dunes and salt-marshes, you will find here Kentish plovers there but also many amphibians and of course the famous “pré-salé” lambs.
The harbour of Portbail
Situated on the commune of Portbail, it is formed by the mouth of the river Olonde. The dunes of Sainte-Marie and the southern part of the dunes of Lindbergh form a strip of sand.
The harbour of Carteret
The port of Carteret was created in the natural harbour, sheltered by the headland of Carteret; a lighthouse was built here in 1837.
