The Blue Mine plunges visitors into the depths of the Earth on a discovery of the daily life of slate miners in the early 20th century. With near-total silence and moisture dripping onto the rocks, visitors must squint as they attempt to move forward in the half-light provided by a few lamps as they descend 434 feet (126m) underground. It is cool down in the depths, with the temperature fixed at 55° (13°C) all year round. Back on the surface, you'll learn about the work of the splitter, who would break the slate into fine plates used for roofing.

Hours of operation: April to November. Visits are only guided and at fixed times. Check the website for actual date and times. Ticket office opening on January 12, 2026.

Admission: Adult from 18 years old €17.00, Teen 12-17 years old €15.00, Child 4-11 years old €13.00, Less than 4 years old is free. Plenty of parking.
