New fewer than three refuges are to be found along this Stage, which rises up to the heights of the Lac Du Chambon and its dam.
Climb unhurriedly up into the tranquil heights where signs of the hand of man steer a course between wilderness and civilisation. Encounter sheep and sturdy mountain hamlets, and admire from afar the distant high mountains and legendary peaks of Les Ecrins.


From the church, go down through the village until you reach a crossroads. Take the road to the right of the library (leading to Les Aymes). You immediately come to a second crossroads, where you continue straight on a road that will turn into a path. Continue to follow this balcony path, below the road. Then join the road and follow it for a few metres, and take a path on your right which will lead to the hamlet of Les Aymes. From the car park in this hamlet, located at a crossroads, turn right onto the road that runs downhill and then carry straight on along this track which will gradually turn into a path. Stay on the path, carrying straight on at the various little intersections. A few hundred metres beyond a small car park, take the path on the left which runs up the mountain side to a flat terrace. Here, at the first discovery path sign, turn left (faster route) or right towards the Lac du Lovitel. You will then come to the hamlet of Les Clots (1,540 m). Then, continue northwards following the La Pisse stream (be sure to follow the waysigns). Cross the upwelling area and continue uphill towards the east. Join a country track and follow it as far as the refuges of Les Mouterres and Le Fay (2,258 m).

4 points of interest

  • Fauna

    Common Midwife Toad

    In Spring, a short note emitted at regular intervals resonates around the lake. It is the mating season for this small terrestrial grey toad, mottled with black and brown; it is the male toad’s song to attract the females. A peculiarity of this anuran is that the male uses his back legs to surround the string of ova laid by the female to fertilize them with a jet of semen mixed with urine. In this way he watches over the eggs for several weeks. When they are on the point of hatching, he goes to the water and frees the young frogspawn.

  • Flora

    Purple Loosestrife

    During the whole summer, the Purple Loosestrife, with its beautiful purple spikes, sprinkles the small Lovitel lake with colour. Considered to be a weed to be destroyed, it does however hold a position among the most useful plants (plants with medicinal properties). Its astringent properties, among others, deem it to be a good remedy against colic in infants when teething. In the kitchen, its young shoots and the flesh of its stalks used to be consumed as a vegetable. The leaves could also be infused like tea.

  • Lake

    Lovitel Lake

    In addition to being one of the rare wetlands at altitude on the highest part of the Romanche, Lovitel Lake unusually partially dries out during the summer and turns in to a marsh.  In this way it becomes ideal for the development of amphibians who benefit from the absence of fish, their predators. Furthermore, the ecological quality of the environment is remarkable... Several species of great natural value are present at this site, notably the Adder’s Tongue Fern and the Small Meadow Rue, both protected regionally.

  • Geology and geography

    Petrifying Fountain

    The water that crosses the Emparis plateau which is composed of permeable sedimentary rock, fills up with Calcium bicarbonate. When, lower down, it comes in to contact with the impermeable crystalline rock layer of the Hercynien granitic base, the water follows a fault plane established between two layers and finishes in an aerial waterfall. The dissolved carbonates are transformed into a soft rock called Tuff by their contact with the air which has accumulated there for millennium. This resurgence, or petrifying fountain, is one of the most beautiful in France.
