All about the fauna and flora From Belle-Île

Belle-île-en-Mer, the largest of the islands of Brittany, is classified as a site of European interest Natura 2000. A large part of the territory is dedicated to the protection of the natural heritage… Numerous plant and animal species flourish there. On land as well as at sea, Belle-île delights nature lovers.

Rare and protected natural resources

On the island schist plateau, alternating coastal landscapes and farmland support an original terrestrial and marine biodiversity of rare and sometimes unique species.

Dunes, moors, flowers

A rich and varied flora

Grey and mobile dunes, coastal moors and wandering heather moors (specifically island environments), cliff top lawns and rock crevice vegetation crown the island. Many varieties of protected plants can be discovered, such as the holosted plantain (regional protection), the gadeceau carrot (national protection), various orchids (national protection), the dodder of godron or the Greek toadflax (endemic – national protection) …

Sea, land, and air

A fauna present in all environments

To the fragility of this flora is added that of the animal populations, whose emblems are the nesting birds, without forgetting the amphibians – as an example, the green lizard is protected at the European level – or the butterflies and other more discreet curiosities.

At sea, often forgotten riches cover the seabed: banks of maerl, underwater meadows and, at the foot of the schistose cliffs, develops the most important population of French barnacle.

The main natural sites of the island

La Pointe des Poulains

This is undoubtedly one of the most beautiful sites on the island…Located at the northeastern tip, in the commune of Sauzon, nature is omnipresent here. This natural site has the distinction of also housing a high point of the island’s historical heritage with the fort of the tragedy Sarah Bernhardt.

I’m discovering!

The Needles of Port Coton

Located due west, on the commune of Bangor, the site allows you to take the measure of the sinuosity and the character so particular of the wild coast. Islands and rocks of all shapes have always fascinated many travelers, the most illustrious of whom is undoubtedly the painter Claude Monet. Before or after your walk to the Aiguilles de Port Coton, discover the Grand Phare de l’île, a stone’s throw away.


The port of Sauzon

If it is always pleasant to stroll along the quays of the port of Sauzon, this one shelters another particularity to discover: its long ria, this stretch of sea penetrating inland. During high tides, put on your boots to discover worms, shells, crustaceans and many other species that hide in the mud.


Donnant Beach

While this beach is well known to surfers for its beautiful rollers, Donnant Beach is also characterized by its dune, one of the most spectacular on the island! The dunes cover about sixty hectares on Belle-île and are home to a very large diversity of plants, sometimes rare and all adapted to the drought.
