The countries of Baixa Cerdanya and Alt Urgell lie along the river basins of the Segre and the Valira, protected to the north by the mountains range of the Pyrenees and to the south by the towering heights of the Cadí. It is a countryside of small rivers running between rich meadows. To the north is the Principality of Andorra, one of the smallest countries in the world.

The climate is typically mediterranean, influenced by the mountains; cold and dry in winter, rainy in spring, hot and dry in summer and mildly humid in autumn. It produces a rich pasture, giving a distinctive "bouquet" to the cows' milk.
