Magnificent historic city, plan a day to visit Bouligons a few kilometers away towards Valdrôme.

Interesting rock formation.

A beautiful climb to a picturesque village offering magnificent views. Two passes to choose from to continue the tour.

It all began in 1442 when a foundation broke away from the southern flank of Pic de Luc. As it slid, it hit a limestone spur, divided, broke into enormous blocks and blocked the Drôme at two points... thus two lakes were formed: the Petit downstream and the Grand upstream. The “Grand Lac” is 5 km long and arouses envy because it is full of fish. In 1561 it thus became the property of the Carthusians of Durban, monks to whom meat was forbidden. It was only in 1804 that a huge block, the “dad”, was pierced to let the water flow at the location of the current Saut de la Drôme. This vast dry body of water now gives way to an agricultural plain (ruined Bouligons farm and its formerly cultivated terraces) and the Bouligons marsh, the last vestige of the disappeared lake. The need to avoid the Claps during the construction of the “Briançonnais” railway line at the beginning of the 20th century also gave the site a magnificent viaduct, 244 m long and 44 m high.
