Cap Fréhel Lighthouse: This impressive lighthouse dates back to the 20th century, but is a successor to earlier structures. It can be climbed – in good weather, you can see as far as the Channel Island of Jersey.

This small communal road allows you to drive in complete peace while admiring Cap Fréhel and its characteristic moors in the distance, tinged with beautiful shades of pink and yellow against the blue backdrop of the sea.

One of the must-see places on the Emerald Coast, beautiful view of the Ehbiens archipelago and the surrounding area. Very different landscapes depending on the tide.
