Huerta Cave

Located in the municipality of Tevega, in the Foz de la Estrechura gorge, very close to the village of Fresnedo, Cueva Huerta is currently the second-longest cave in Asturias in terms of the total length of its passages (14.5 kilometres). It forms part of a unique karst complex, comprising a gorge, a sinkhole, a large cave, various underground watercourses and a resurgence.

The gorge, or ‘hoz de la Estrechura’, which lies between the Sierra de la Sobia and Peña Vigueras, is formed of Carboniferous limestone. The cave, which has a complex hydrological system, acts as a sinkhole and an underground channel for the River Sampedro.

The caves can be visited, but always under the supervision of a guide. Two types of tour are available. One is the footbridge tour, a walk along the cave’s footbridge, lasting around 50 minutes and suitable for most people. The other, more challenging tour involves a walk along the riverbed, lasting approximately 2 to 3 hours depending on the number of people.

Partially open to visitors. It is recommended that you book your visit in advance. Out of season, we also organise private tours for groups any day of the week.
