Château d'Entremont

Château d'Entremont stands as castle ruins perched on a narrow headland at 948 meters elevation, commanding views over the deep gorges of Frou and Entremont Valley. The remaining stonework allows visitors to trace the original defensive layout of this fortress.

The fortress was constructed between 1306 and 1339 by the Entremont family to serve as a strategic defensive stronghold. Its decline came during the French Revolution when such fortifications lost their importance.

The site carries the name of the Entremont family who established their stronghold here centuries ago. Visitors can sense how the location shaped life for those who lived within these walls, with the surrounding landscape playing a central role in their daily existence.

A loop trail of about 6 kilometers with a steady climb crosses bridges over the Guiers and Cozon rivers on its way to the ruins. Sturdy footwear is essential as the path includes steep sections and narrow passages, particularly after wet weather.

A stone orientation table at the ruins displays engraved names of the surrounding mountain peaks in the Chartreuse region. This marker helps visitors identify the ridge line and understand their position within the broader landscape.
