Blaenau Ffestiniog
Blaenau Ffestiniog is a historical mining community in Wales, in the historical area of Merionethshire, although now part of the unitary authority of Gwynedd. The population of the area of Ffestiniog was 4,875 according to the 2011 census, including the neighboring village of Llan Ffestiniog, which makes it the 4th most populous community in Gwynedd, after Bangor, Caernarfon, and also Llandeiniolen. Llan Ffestiniog's population of 864 puts the population of Blaenau itself at around 4,000. Blaenau Ffestiniog was at one-time the 2nd largest town in North Wales, behind only Wrexham. After getting to 12,000 at the peak growth of the slate sector, the population fell with the decline in the need for its slate. Today the town counts heavily on visitors, that come for attractions that include the neighboring Ffestiniog Railway and also Llechwedd Slate Caverns. As the slate industry declined, the population of Blaenau Ffestiniog has likewise declined, to 4,875 in 2011. At the same time the tourist market has ended up being the community's biggest employer. The revitalized Ffestiniog Railway as well as the Llechwedd Slate Caverns are prominent vacationer destinations, as is the Antur Stiniog downhill mountain cycling centre. Recent tourist attractions include the Zip World Titan zip-line site, which also now includes the Bounce Below slate mine activity centre.
