A great beach for relaxing and swimming in summer, a hotspot for surfers and windsurfers all year round. In addition, the peninsula provides a reference point to the millennia-old history of Brittany.

Cape with good views towards the harbor and the open sea. You can still see traces of its former use with a ramp, seawater tanks and a quarry.

In addition to the obvious traces of the cape's former use (see description), you have a fantastic view of the harbor and the open sea. A real highlight.

This listed natural site has always attracted walkers. Following the GR34, the coastal path, we discover rocks with mysterious shapes: rabbit ears, the rhino, the corkscrew, the turtle or the rock of the victims. These rocks owe their particular shapes to phenomena of alteration and erosion caused by rain, wind and sea spray. An ancient Hercynian mountain range, formed between 480 and 300 million years ago, the site is also a gold mine for geologists. The landscape is magnificent during storms. Lovers of beautiful waves and raging seas must, however, never neglect the dangerous nature of the place, even in calm weather. The name given to the rock to the victims is not trivial. Picnic tables and parking are available to visitors.
