Travel 500ft underground for a guided journey through the historic slate chambers of Llechwedd. Follow miners' footsteps, encounter light and sound installations, and finish beside an extraordinary underground lake before returning by cable railway.
Arrive 30 minutes early to check in, collect a hard hat and meet your guide near the underground station. The group begins by descending 90 steps along a route once used by miners.
As you move through ten slate chambers, the guide brings the mine's stories to life with artefacts, projection and light displays. The route is paced for looking, listening and understanding the landscape beneath the mountain.
The final chamber opens onto the underground lake for a memorable light and sound moment. Your guide then leads the group to the cable railway for the 500ft return to the surface.
Llechwedd sits close to Blaenau Ffestiniog in the dramatic slate country of Eryri. Its underground spaces are a direct link to the region's industrial heritage and the people who worked here.
The town is reachable by road and rail, with mountains and heritage attractions nearby. The site makes an atmospheric stop for families and curious visitors exploring North Wales.
Everyone must be able to walk the route, including the initial 90-step descent, and should be physically comfortable underground. The caverns remain cool year round, so warm clothing and sturdy footwear are important.
No specialist knowledge is required because the guide leads the entire experience. Under-18s need one participating adult for every five children, ensuring younger visitors stay supported throughout.

The route explores ten historic mining chambers. Each chamber has its own atmosphere and helps reveal a different part of the mine's working history.
Along the way, the guide uses stories, artefacts, projections and light displays to bring the spaces to life. The visit is about the landscape and people connected with it, rather than simply passing through.
Wear warm layers and sturdy trainers or boots because the caverns remain at around 6 to 8 degrees Celsius throughout the year. Comfortable footwear is important for walking the underground route.
