The Cliffs of Carolles and Champeaux

The most beautiful kilometer in France

The cliffs of Carolles and Champeaux offer breathtaking views of Mont Saint-Michel and its bay. You’ll also discover two cabanes Vauban, small stone guardhouses built in the late 17th century along the coastline to fortify the French coasts. Last but not least, these cliffs are ecologically diverse, as well as being of great scenic interest.

Exceptional flora and fauna

and a marvellous view of the Bay of Mont Saint-Michel

The falaises de Carolles et Champeaux, safeguarded since 2001, present a great biological diversity but also a real landscape interest due to the magnificent panorama they offer over the Baie du Mont-Saint-Michel.

The high cliffs of this granite massif are perhaps the most beautiful belvedere to be found on the bay.

Averaging 60 to 80 meters in height, they are covered with heather, gorse, broom and blackthorn moors that offer, depending on the season, a formidable palette of colors ranging from lemon yellow to crimson pink.

This granitic massif is notched by a valley at the bottom of which flows the Lude, which empties into the sea at the Port du Lude.

These cliffs are renowned for being a mecca for bird migration, and several insects (locusts, grasshoppers, crickets) and reptiles (green lizard, smooth coronet) have made their home here.

The entire Carolles and Champeaux cliffs site extends over 5 km in length. This remarkable natural heritage benefits from a management plan by the Conservatoire du Littoral, which has counted 480 plants, 30 species of orthopteran insects, as well as 348 species of butterfly.

Hermel reef

Europe's largest

At the foot of this massif (below Champeaux), at low tide, we find the largest hermella reef in Europe, some reaching up to 1.5 meters in height.

These colonies of small marine worms build 30-centimeter tubes of sand grains and shell debris on the rocks.

Please avoid trampling these fragile natural habitats home to a diverse marine fauna.

At the foot of the cliffs, on the site du Sol Roc, low tide uncovers the remains of ancient stone fisheries dating back to the 12th century, witness to an intense traditional fishing activity.

Cohorts of fishermen still flock at ebb tide in search of “chevrettes”, the local name for grey shrimp. The foreshore allows fishing for cockles, clams and prawns. On the rocks you can find oysters, mussels, periwinkles.

In the distance, the huge oyster beds and bouchots at low tide bear witness to the bay’s formidable biological productivity, which enabled this veritable “shellfish industry” to emerge from the 1950s onwards.

The foot fishing is practiced all year round with a tide coefficient of at least 80.
