Second Natural Park to have been created in France in 1969, the Armorique Regional Natural Park is a concentrate of all breton landscapes. It covers four distinct areas: the Iroise Sea islands (Ouessant, the archipelago of Molène and Sein), the Crozon peninsula, the maritime Aulne and the Monts d'Arrée. The park covers 172000 hectares, including 60000 hectares of sea and coastline. It  radiates strong charisma and boasts great wildlife, for instance otters, beavers and salmons.
The Iroise Sea  harbours the greatest seaweed field in Europe, and most fish species of the Atlantic coast of France are represented. Colonies of great mammals, like grey seals and bottlenose dolphins, have settled down in the well-preserved waters of the Molène archipelago, which bears the label “Réserve de la biosphère”, awarded by the Unesco. Same as Ouessant, which, by the way, features one of the busiest sea passages in the world.
The Crozon peninsula enjoys great renown  due to the beauty of its imposing landscapes, like the cliffs lining the “cap de la Chèvre” with pine trees, as well as to the blooming wealth of its plants and animal wildlife. On the edge of the heath, a small wild flower has chosen home. The “Crozonnaise”, a protected species, peppers the landscape with a blue touch, unusual for this type of vegetation.
The maritime Aulne links Brest harbor to the canal from Nantes to Brest, between the Monts d'Arrée and Ménez-Hom. As the estuary of one of Brittany's greatest coastal rivers, this stretch of the sea offers a  wide rang of habitats for the local fauna, due to the wealth of the environment between land and sea,  and between salt and fresh water: saltmarsh, saltmeadow, tidal mud flats, lagoons, dunes, pine forests,... Lesser known, this outstanding setting is yet well-worth exploring, and  especially favorable for hiking.
A stroll along the arid escarpments of the Monts d'Arrée will undoubtedly provide you with a complete change of scene. Offering stunning panoramas over the region, these ancient rocks, rounded and boldly sculpted by time and weather, tower up at 384 meters heights. With the rocky outcrops amongst the short heather, the wild and mysterious appearance of the setting reminds of certain Welsh or Irish landscapes. Lunar scenery spreads out as far as the eye can see, and noone would even think of being surprised if a fairy should suddenly show its face.
