shows the history of slate quarrying in the town. One of north Wales' premier tourist attractions, and with good reason. The Deep Mine tour involves some walking, including steps, and takes you down as far as 450 ft below the summit of the mountain. This tour starts with a ride on Britain's steepest passenger railway, dropping down several levels within the mine. There follows a walking tour through 10 of the huge "chambers" within the mine. There are a number of attractions and displays on the surface, including the Victorian Village which aims to paint a picture of daily life for local people in the mid-19th century. Can get fully booked on busy days such as bank holiday weekends so worth booking in advance to avoid disappointment.
Llechwedd is a visitor attraction near Blaenau Ffestiniog, Gwynedd, Wales. It details the history of slate quarrying in the town and specifically the Llechwedd quarry in which it is located. The main aspect of Llechwedd is its Llechwedd Deep Mine Tour which has the steepest narrow gauge railway in the UK and travels over 500 feet (150 m) underground to the disused slate caverns, and the Quarry Explorer Tour which heads out to the furthest reaches of the Llechwedd site to explore the history of mining in the area.
