This area is formed by the departments of San Carlos, Tunuyán, and Tupungato.

Its main river, the Tunuyán, fed by the rivers Las Tunas, Colorado, Salinillas, and the brook Manzano, among others, irrigate all the oases of the Uco Valley, which covers about 55,000 hectares. The valley bases its economy on the cultivation of the vines, olive trees, vegetables and fruit. The length of their crops is alternated with food industries, warehouses and storage, as well as fruit packing places.
