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.

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!

Cannon at Pointe de l'Isle

Highlight • Monument

The tip of the Isle looks out over the Atlantic, placid. There you will find a semaphore, an orientation table, and a cannon dating from the mid-18th century. Legend has it that the cannon was found at the foot of the cliffs, more than 200 years after its fall.

Saint-Cast

Highlight • Settlement

Saint-Cast is rightly considered one of the most beautiful coastal towns in northern Brittany: one and a half kilometers of white sandy beach on the Grand Plage (or Plage des Mielles) and everything that makes a seaside resort, in the district of La Garde, winding lanes steeply on the hillside in L'Isle , boat harbor, beach boulevard, shops and restaurants of all kinds.

View of the Emerald Coast from Lower Saint-Cast

Highlight • Viewpoint

At the bottom of a basin that makes your calves creak as you leave, but it's worth the look!
