This wild trail along a lakeshore path offers new perspectives. The showstopper is at the Chanteloube viaduct.
From the Baie St-Michel, follow the shores of the Lac de Serre-Ponçon for several kilometres. A succession of rises takes you to numerous combes with their characteristic black earth. Relish the shade as you pass through forested areas. Then, in no time at all, you are back near the lake, admiring the view. At the end of the trail, discover the famous Chanteloube viaduct, which is totally submerged in the summer season.

7 points of interest

  • Panorama

    Panorama of the Baie Saint-Michel

    This area, which has been provided with picnic amenities, offers the most picturesque panorama over the Lac de Serre-Ponçon. In fact, the lake is 2 kilometres wide at this point, and in front of you are the Chapelle Saint Michel and the Pic Morgon, an iconic view of the lake. On your left, to the east, you can see Savines-le-Lac and its bridge. On the right, you can see the secret île de la Tortue.
  • Geology and geography

    Gullied black earth

    Prized by mountain bikers, Terres Noires, or black earth, is formed from rocks which erode easily. The flows caused by precipitations shape and sculpt these friable marls. In the Alpine region, numerous examples can be seen, in particular on slopes, which vary in gradient depending on the area, which increases the speed of the water flow.
  • Fauna

    Burnet moth

    This is a medium-sized moth (25 - 35 mm wingspan), often brightly coloured: the inner wing has a maximum of six spots. This burnet moth is found on the edges of calcareous meadows, steppe-like slopes, dry bushes and clearings in dry forests. This remarkable species is a sign of the quality of the habitats but it is not at risk so does not appear on the list of threatened species.
  • Flora

    Downy oak

    The oak has a dark grey bark which is deeply fissured. Its lobed leaves, downy on their undersides, remain dried out on the tree until the spring. The fruits, called acorns, ripen in the autumn. The oak can grow at up to 1,500 metres above sea level, on well exposed slopes. Also called the white oak, the downy oak is well known for hosting truffles among its roots. This fungus develops 30 to 40 cm underground, and the difficulty in finding it makes it a culinary delicacy.
  • Fauna

    Western green lizard

    This lizard can be spotted from April through to late September. The species is in hibernation for the rest of the year. It hunts in areas with dense vegetation and feeds primarily on insects and invertebrates. It exhibits sexual dimorphism, that is to say, during the breeding season only, the males have bright blue colouring on the throat and sides of the head. Mating takes place around May. The males engage in fights, in which they occasionally lose their tails.

  • Fauna

    Grey heron

    This is a tall bird (85 to 102 cm). Its white head is adorned with two large black eyebrows. Its back and wings are ash grey, hence its name. Its legs and beak are yellowish in colour. It uses its long, powerful beak to catch large prey (fish, amphibians etc.). In flight, its neck is folded back forming an «S». This species is wholly protected by regulations.
  • Vernacular heritage

    Chapel of St-Jacques

    Located in Chanteloube, this church is through to date back to 1510. It has retained all its authenticity, with its exposed stone. It is dedicated to Saint James, one of the 12 apostles and one of the first martyrs of the Catholic church. Its recent restoration has made it possible to hold the traditional celebrations there, in honour of Saint James. The purpose of each one is to commemorate a historical event connected with the saint. When he died, he was taken to Compostella in Spain, hence the name of the pilgrim's Way of Saint James to Santiago de Compostella, a religious route passing along the shores of the Serre-Ponçon lake.
