Gué Saffray quarry

Highlight • Other

Dug into the rock bar separating Mortain and Domfront, this former quarry offers beautiful landscapes. Below, the view mixes rock and vegetation. The small path that leads to the top is lovely. As for the heights, they release even more the vision for the greatest pleasure of the hikers.

Calvaire du Roc

Highlight • Monument

Each of these crosses, which the traveler often encounters in the fields or, as here under the name "Calvaire du Roc," at the top of the rock, is a sign commemorating the crucifixion and resurrection of Jesus Christ. "Here on earth, His memory exists, but in the Kingdom of Heaven is His presence: this presence is the joy of those who have already attained salvation. Remembrance is our comfort, we who are still wanderers, traveling towards our homeland." (Saint Bernard of Clairvaux, c. 1090–1153)

Fosse Arthour

Highlight • Gorge

70 meters deep, this gorge has many attractions. On the heights, you will find a superb panorama as well as a Calvary marking the highest point of the ridge. In the rocks, two legendary caves symbolize the chambers of King Arthur and Queen Guinevere, hence the name Arthur Pit (Arthur). Below, the river having dug the gorge, the Sonce, is transformed into a waterfall. An artificial pond that was created to regulate the flow is also nearby. Not to mention the inn on the site, ideal for regaining strength after strolling around the site: aubergedelafossearthour.com
