Allein is a typical small mountain village situated on a splendid sunny position on the left side of the Artanavaz river, 15 km from Aosta on the SS 27 Great Saint Bernard road.

Sightseeing: in the hamlet of Ayez, there is an ancient house dating back to the 15th century with some particularly decorative worked-stone windows with a characteristic ogee motif. This building has been restored and become the seat of a museum and a library.

The territory of Allein offers a wide range of paths and itineraries for summer excursions, the most important is the one to Mont Saron (2631 mt), a peak which is easy to reach and which is also the destination of an annual religious procession taking place at the end of July.

Talking about folklore, worthy of mention is Carnival which is celebrated by the population of the village in the month of February with a parade of multicoloured and typical costumes which recall the uniforms of Napoleonic soldiers. The typical festival of this village is called “Feta di Trifolle” dedicated to the potato which takes place every year at the end of August.
