The park contains the highest point in Western Brittany, the Menez Hom, which reaches an elevation of 330 meters.
Its geological history includes traces of the Variscan orogeny, which shaped the landscape over 300 million years ago.
The Crozon Peninsula features rare examples of folded sedimentary rocks visible directly along the shoreline cliffs.
The park's territory includes the Ouessant and Molène archipelagos, which form part of the Iroise Sea Biosphere Reserve.
It is home to the last remaining Atlantic moorlands of the Armorican massif, providing habitats for rare species like the marsh fritillary butterfly.
The Aulne River estuary inside the park is a complex tidal environment that influences the local microclimate and biodiversity.
Armorique Natural Regional Park is a UNESCO Global Geopark spanning 125,000 hectares in Brittany, France. It encompasses diverse geological zones including the Monts d'Arrée sandstone ridges and the Crozon Peninsula's cliffside coastlines. The park covers four distinct geographic sectors: the maritime Iroise Sea islands, the Aulne estuary, the Menez Hom mountain, and the granite-based interior. It functions as a protected area for both biodiversity conservation and cultural heritage preservation of Breton traditions. The park office is headquartered in Le Faou, a historical village classified as one of the 'Petites Cités de Caractère'. It features expansive heathlands, peat bogs, and ancient maritime defense sites. The park promotes sustainable tourism through extensive hiking networks and geo-educational trails.
