ADRECAG’s territory is formed by the Alba de Tormes, Campo Charro and Guijuelo regions.

The Alba de Tormes region is located in the centre-west of the province and is bathed from north to south by the waters of the River Tormes, whose waters are controlled by the Santa Teresa dam and the Villagonzalo diversion dam. The Campo Charro region is formed by large plains surrounded by gente mounds; the region’s boundaries do not correspond to an administrative division, but rather to a historical and touristic one. The Guijuelo region is located in an undulating intermediate area between the plains of Alba de Tormes and the mountainous region of Sierra de Béjar.
