Local area
Moelferna is on the upper slopes of one of the flanks of Moel Fferna. This is south of the village of Glyndyfrdwy, which is situated between Llangollen and Corwen on the A5. This area is not as noted for its slate mines as Ffestiniog, but nonetheless, Moelferna is an impressive undertaking.
About Moelferna
All of the adits leading into Moelferna were blocked upon closure of the mine. However, one ventilation shaft was left open in the hillside above the mine in a small crater. The shaft has a tree growing conveniently at the top, making a good point to abseil in from.
Inside there are many immense chambers, spanning many levels and with very high roofs. Interesting things to see are the intact bridge, hand pump, inclines and cog holding the roof up.
Moelferna is large and irregular, arrows are a good way to avoid getting lost.
