Blaenau Ffestiniog was once the capital of the slate quarrying industry. Now, one of the old quarries has been turned into a major tourist attraction.
At Llechwedd Slate Caverns you can take the Miner's Tramway into the side of the mountain and into a succession of spectacular chambers where a miner describes the working of the mine.
Alternatively, you can ride down the underground cliff railway into the dramatic Deep Mine, and experience the audio-visual presentation as a miner from long ago takes you through the various chambers.
The narrow gauge Ffestiniog Railway links Blaenau Ffestiniog with Porthmadog on the coast. The ride is spectacular as the line twists and turns its way through the countryside.
Ffestiniog Power Station at nearby Tanygrisiau was the first pumped storage station built for the CEGB - an example of modern technology set against the dramatic backdrop of old slate quarries. There is an exhibition, and tours.
