August 25, 2025, Coastal Path in Parc Naturel Régional Vallée de la Rance - Côte d'Émeraude

A dream of a hiking trail, but not for light footwear or those in poor physical shape. It's all up and down over roots and rocks and dusty paths.

Quite nice here 😉 At least for a little picnic and break, as the coastal path is quite challenging.

A quick respite from the ups and downs of the coastal path with easy access to the beach. Sometimes the air here just isn't so fragrant 🤢

Ruins of a historic mill that was fed by the Ru de Matignon. The mill is not only a popular hiking destination, but can also be easily incorporated into a mountain bike tour. The trails along the Ru de Matignon or from La Forge are absolutely worthwhile.

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.
