Mallos de Riglos
From Wikipedia, the free encyclopedia
The Mallos de Riglos are a set of rock formations in Huesca, Spain, some 45 km (28 mi) to the northeast of the city of Huesca. Rising to some 300 metres (980 ft) high (c. 1000 metres or 3,300 ft above sea level), they form part of the foothills of the Pyrenees.
Because of their relatively vertical sides, the Mallos de Riglos are a popular destination for climbers.
