La Banche Beach

Highlight • Beach

Due to the extreme tidal difference at this part of the channel, the lovely beaches are only good for bathing a couple of hours around high tide. At low tide the firm sand allows to cross the bay and even walk out to the Ébihan islands.

Guildo Castle

Highlight • Castle

The ruins of the Château du Guildo rise above the mouth of the Arguenon.
The castle was once the property of Prince Gilles of Brittany, whom his own brother, Duke François I of Brittany, had imprisoned and murdered for quarrels over inheritance and prestige.

View of Gilles de Bretagne Castle from Pont René Pleven

Highlight • Viewpoint

From the bridge, enjoy the view of the ruins of the castle on the right bank of the Arguenon. In the 15th century, Gilles van Bretagne lived here, a poet and womanizer who lived a merry life, hence the expression "courir le guilledou" (to go on a woman hunt). But his brother, Duke Francis I of Brittany, suspected Gilles of plotting and had him imprisoned. Because he didn't die fast enough, he was then strangled. Before his death, however, Gilles subjected his brother to divine judgment, and the duke also died, tormented by remorse.

Port Nieux

Highlight • Beach

There is no spa here, but nature, the evocation of the tragic events of the Second World War, mud and birds. Further on, the serene castle beach accessible by the coastal footpath, tropical at high tide, remains one of the most beautiful spots on the Côtes d'Armor. A must in good weather, especially when motor yachtsmen do not come to disturb this lost corner with Caribbean allure....

Le Guildo

Highlight • Settlement

The clean houses are in a side street on the left (when you drive to the ruin). So don't rush!
