Pont Naturel du Bonheur is located close to the village of Saint-Sauveur Camprieu on Causse de Camprieu (Cèvennes National Park) on Gard department of France. The natural bridge was formed by the collaspe of the roof of the former natural tunnel just before that Bonheur river fall into his undeground course about several hundred meters until the river exit out from Abîme de Bramabiau. The natural bridge has a measured depth of 95 meters. From the village center, a short signed trail goes to this area called Perte du Bonheur. Edouard-Alfred Martel (a french caving pioneer) & friends was the first in 1888 to connect Perte du Bonheur to Abîme de Bramabiau following the narrow underground river.
