Tolox lies between the rio de los Caballos and the rio de los Horcajos at the end of a side road hanging like a loose thread from the C-344 Málaga-Ronda highway. When they reach the village the two rivers call a truce and combine to form the rio Riachuelo.

The Balneario de Fuente Amarga (Bitter Fountain) was established in 1867 and its waters declared for public use in 1871. It is located in the village of Tolox one hours drive inland from Marbella or Malaga at 360 meters above sea level at the entrance to the Sierra de la Nieves Natural Park and has clear air, a splendid warm climate, abundant water and green vegetation - a sheer delight in contrast to the pollution and stress of modern life.
