Magnificent beach with few people, one of Brittany's great assets

This pretty marina is very pleasant for a stroll. A promenade provides access to the beach and the town centre of Saint-Cast-le-Guildo.

The stairs are relatively steep and long, so it's better to walk instead of run. There is also a steep ravine for those who don't like steps.

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.

Nice section of the GR34, also marked by the VTT-22. Technical passages with steep inclines alternate with relaxed cruising. Lots of hikers in the season. Contrary to other statements, the further route towards Saint Cast is not passable.
