Huerta Cave

Located in the municipality of Tevega, in the Foz de la Estrechura gorge, very close to the town of Fresnedo, Cueva Huerta is currently the second largest cave in Asturias in terms of the total length of its galleries (14.5 kilometres). It is part of a unique karst complex, made up of a gorge, a sinkhole, a large cave, several underground channels and a resurgence.

The gorge or gorge of La Estrechura, which is squeezed between the Sierra de la Sobia and Peña Vigueras, is formed by carboniferous limestone. The cavity, which has a complex hydrological functioning, acts as a sink and underground channel for the river Sampedro.

The caves can be visited, but always under the supervision of a guide. There are two types of visits. One is the walkway visit, a tour along the cave's walkway, which lasts about 50 minutes and is suitable for most people. The other, more complex, consists of a tour along the riverbed, which lasts approximately 2 to 3 hours depending on the number of people.
