Pozo Sotón features the longest and deepest guided mine tour accessible to the general public in Spain.
The mine was active for over 90 years, with coal extraction beginning in 1923 and concluding in 2014.
Visitors wear authentic mining protective gear, including headlamps and self-rescuers, during the underground descent.
The site contains the original 'castillete,' or headframe, which remains one of the iconic silhouettes of Asturian industrial heritage.
The underground tour allows visitors to operate some of the original drilling machinery.
The museum is part of the European Route of Industrial Heritage (ERIH).
The mine's extraction shaft extends to a total depth of nearly 600 meters.
Pozo Sotón is a former coal mine in Asturias converted into a Heritage Museum and Mining Experience center. It is one of the few places in Europe where visitors can descend 586 meters underground into actual working galleries. The site preserves authentic 20th-century industrial machinery, including the original headframe and vertical shaft lift. It functions as a living laboratory for industrial archaeology, highlighting the socio-economic history of the Nalón Valley. Visitors traverse the underground tunnels used by miners to extract coal, offering a raw view of the physical labor involved in deep-pit mining. The site maintains the surface administrative buildings and workshops to provide a complete picture of mine logistics.
The elevated walkway near the top of the industrial headframe offers a view of the mine complex and the valley.
Underground temperatures remain constant year-round, so dress in layers regardless of the weather outside.
Physical fitness is required as the underground experience involves significant walking and navigating uneven terrain.
Book your underground visit well in advance as group sizes are strictly limited for safety reasons.
Do not attempt the underground tour if you suffer from severe claustrophobia or limited mobility.
Closed on certain weekdays during the low season; check the official calendar for winter schedule variations.
