Pozo Sotón (HUNOSA)

A HUNOSA mine shaft in San Martín del Rey Aurelio with a real descent into the mine, to a depth of 386 m, an outdoor visit, a museum and dramatised visits.

The Pozo Sotón is a HUNOSA coal pit in San Martín del Rey Aurelio that can now be visited: from outside, with the machine room and the track yard, and from inside, going down in the cage to the eighth, ninth and tenth levels, between 386 and 556 metres below the surface.

The visits

The long visit goes down to the eighth level, continues through the La Jota chimney to the ninth and covers about two kilometres of galleries to the working areas, with a vertical face with a shearer and a sublevel face; it takes between four and five hours and about 5 km of underground walking, for €48. The short visit, of two and a half hours, is listed in November 2026 as temporarily out of service. There is also an outdoor visit, a museum, dramatised visits and a mining escape room.
