The département of Calvados' leading natural preserved site, the Orne estuary is of major ecological interest. It provides a habitat for a remarkable array of fauna and flora, including many rare species, protected regionally or nationally. Marked walking routes, orienteering tables, information panels and observatories offer visitors the ideal environment to discover the estuary.
In the heart of this natural site, the Maison de la nature et de l’estuaire (Nature and estuary centre), the property of the Calvados Council, invites you to discover the estuary's many treasures.
