Lovely route, first along the coast on good cycle paths, then after the large car park via all sorts of narrow roads and villages back to the campsite in Ceaux.

The famous rock alignment known as the Druids' Line is as intriguing as it is fascinating. What are eighty quartz blocks doing, stretching over three hundred meters, in an area where this type of stone doesn't exist? Was it a religious or pagan practice? To date, no researcher has found the answer. The Druids' Line follows a general north-northeast orientation, despite numerous meanders. This type of alignment, in a single line, is quite rare in Brittany. It is mistakenly called the Druids' Line, as it is not a Celtic installation, dating back to the Neolithic period.

The Église Saint-Léonard was built in the 12th century and acquired its present form in the flamboyant Gothic style in the 15th and 16th centuries. During the French Revolution, the church was deprived of its sacred function, but in the 19th century, under architects such as Aristide Tourneux, it underwent extensive renovations, including a new main façade with a large rose window. Inside, 19th-century stained-glass windows depicting episodes from the life of Saint Léonard can be seen.
