While you wait for a clear night sky in Saint-Barthélemy (we can't forget that this is the location of the Regional Astronomical Observatory), don't miss the chance for a ski "trial lesson" on the surrounding slopes. Sunscreen and sunglasses should not be forgotten, because the 30 km long resort has no less than 250 days of sunshine per year. The cross-country trails cross the snow-covered meadows of Lignan, reaching an altitude of 1,700 meters at their highest point and the village of Champcombre, where the tracks begin at 1800 meters. There is a huge panorama to see: the Val Clavalité, the great valley of Saint Marcel and Mont Emilius in the south; the gorge of the Saint Barthélemy valley in the north. The slope at Lignan, starting from the town square, directly above the church, extends over a circuit of 3.5 km and in two circuits of 2 km, with easy to medium difficulty. The slopes of Champcombre start in the small hamlet of Porliod and extend to the upper valley of Saint Barthélemy, following the extensive semicircular morphology, until Ollière, at an altitude of 2000 meters. The slopes in Champcombre follow a linear route, on the sides of which there are three circuits: each of the routes can still be followed, from one to the other via dedicated transfer tracks. The direct route is of easy to medium difficulty and is located far from roads and inhabited centers, in a beautiful natural environment.

Arriving from the upper mountain pasture, on the descent from Cunéy to the Magià refuge, the path suddenly changes and you enter this suggestive and stony stretch with beautiful small waterfalls

Valley full of stony ground that falls from the surrounding mountains. The climbs to the routes are quite steep and the ground is slippery. There could be cows grazing

The stone bridge allows you to cross the Buthier Creek. It is very impressive to see how the force of water over the centuries has carved a deep gorge.
