One of the world's purest skies
Saint-Véran, with 150 clear nights a year (30% more than the famous Pic du Midi de Bigorre in the Pyrenees), is second only to such mythical sites as Chile and Hawaii. Measured scientifically by an index of visual purity called “seeing”, the Château-Renard – Paul Felenbok astronomical observatory gives access to one of the five most beautiful skies in the world.
