Valais is one of the 26 cantons of Switzerland in the south-western part of the country.

It is near the valley of the Rhone River from its springs to Lake Geneva, that separates Pennine Alps from the Bernese Alps. The canton is one of the drier parts of Switzerland in its central Rhone valley. It is also one of most well-watered parts, having large amounts of snow and rain up on the highest peaks in Switzerland. It is perhaps best known worldwide for the Matterhorn.
