Caldoveiro Peak, Mountain summit in Yernes y Tameza, Spain

Caldoveiro Peak is the highest point, at 1,354 metres, of a protected sierra of 11,359 hectares in Asturias, near Villabre. The range spans the councils of Proaza, Yernes y Tameza, Grado and Teverga and is divided into four zones: the puertos de Marabio in the centre, the Xordón and Cavadura basins in Grado, the Tameza basin and the larger Trubia and Teverga valleys.

The Sierra del Caldoveiro was granted protected status by the Principality of Asturias as the Paisaje Natural Protegido del Pico Caldoveiro, covering 11,359 hectares across Proaza, Yernes y Tameza, Grado and Teverga. That figure was never developed and has no management instrument, so only the general environmental legislation applies. The sierra also falls within the Peña Ubiña-La Mesa natural park and contains the Monumento Natural de los Puertos de Marabio.

The stone huts called corros stand in the high pastures of the Puerto de Marabio, in the centre of the range, where livestock still graze in summer. The name Caldoveiro comes from the Asturian words for 'hot' and 'spring', referring to a thermal spring on the mountain's slopes.

The summit is an easy ascent from the village of Villabre. The range is included in the Peña Ubiña-La Mesa natural park and contains the Marabio ports natural monument. The protected landscape figure of Pico Caldoveiro has no management instrument, so generic environmental legislation applies.

The sierra lies within the Peña Ubiña-La Mesa natural park and contains the Monumento Natural de los Puertos de Marabio. The regional government declared a "Paisaje Natural Protegido del Pico Caldoveiro" over the Marabio pastures, but no management instrument has ever been drawn up, so only general environmental law applies.
