Llanfair Slate Caverns

Harlech, Gwynedd

Put on a hard hat and make your way down Jacobs’s ladder into the labyrinth of underground caverns, where you can take a self-guided tour by torchlight. When you emerge at the end of the tunnel you will be greeted with fabulous views looking over Cardigan Bay and Shell Island.
