Perched atop Mount Bel-Air, the highest point in the Côtes-d'Armor region, the Notre-Dame du Mont-Carmel chapel watches over the valley. Its octagonal architecture and radiating aisles make it a unique place. The view from the summit alone is worth the climb.

The Gouessant River forms a body of water here, right in the heart of Lamballe. Fed by the river of the same name, it reflects the surrounding trees. It's a lovely spot for a quiet break or a stroll just a stone's throw from the center.
