    The official source of water is located at Fuente de García, in the Montes Universales, within the municipality of Frías de Albarracín (Teruel). It is located at an altitude of approximately 1,590 meters, surrounded by pine forests and high mountain meadows.
    Access is very easy and well signposted. Take the A-1704 highway, which connects Frías de Albarracín with Huélamo (Cuenca). From the highway, a paved detour of approximately 2 km takes you directly to the recreational area and the monument. There is free parking next to the monument.
