Benches along walking or cycling routes are not that common in the Drôme, but when they are there, they offer a beautiful view. The bench is hard to miss and is right next to the road, but there is rarely any traffic here, so take your time and enjoy this beautiful region.

Very friendly welcome from the couple who run it. They offered to store my mountain bike while I hiked the “vulture path”. Delicious food and beer…

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.
