The mullet (father: donkey, mother: mare) is champion for mountain transport. Its rather large size does it most of the time prefer to the donkey, and unlike the horse it has the mountaineer foot and ignores the vertigo. There are good mules and mules that are almost impossible to conduct, because of their character, so it is necessary to try it before buying it. A mullet carries 50 to 80 kg, depending on the length of the race. In winter it can tow a sled to transport loads (manure, hay), it allows to make profitable it a little, because a mullet eats twice as much hay as a cow. There are very few mullets still active in the Arvan. Formerly donkeys were also used, they eat less and are also quite enduring, and may be less delicate from a health point of view.

​

The owner of the mullet never actually climbed on it, because it circulates very seldom without load as at the ascent as the descent. At the climb, the one who leads can be pulled by taking the tail in the hand.

The ancestral paths are excellent by their regular slope. It is possible to find the old paths on the maps (with the altimeter) and the old aerial photos, then to restore them. They were kept in good condition by the passage of the beasts grazing the discards along the road, and plow with the hooves. The ravine passages were maintained manually. If the alp is no longer used, the paths are often overgrown with trees, bushes, rhododendrons. It is easy to cut this vegetation with a large pruner geared down (this instrument looks like a bolt cutter, the shears not multiplied enough are not enough), and the log saw. Some passages also need a fake shot. For the ravine passages, one can use the "Savoyard pick.

​

It is important to rehabilitate, and follow these paths even downhill, because they limit the gully, and because they are beautiful. They too are part of the mountain heritage and are the witness of alpine life. In the climb, their regularity can carry heavy loads that would be difficult to climb without a path.
