There are several downhill ski resorts, the three largest being Ax-Bonascre, Les Monts D'Olmes and Guzet-Neige. There are many cross country ski-ing resorts, one of the best being at Plateau de Beille, near Les Cabannes. Ariège is one of the least populated and most unspoiled regions of France. The locals enjoy keeping traditions alive, especially old farming techniques. Consequently, as fewer insecticides, for example, have been used, the flora and fauna of the area continue to be rich in both diversity and numbers. Butterflies are common and birds are numerous; particularly noticeable are large birds of prey, including the magnificent Griffon vultures.
