Cwmorthin has a tranquil charm with its abandoned buildings and beautiful lake all sitting in a slate-lined mountain bowl. Less well known than the Dinorwig quarry at Llanberis, it’s the perfect place to get some atmospheric photos. Further up on the mountains vast areas of abandoned structures are a reminder of the sweat and toil that industrial Wales endured. You will see evidence of the tramways, inclines, mills and machinery. We start out in Tanygrisiau where workers’ vernacular settlements, schools and meeting-places are examples of a traditional way of life.

The trail eases through the mountains, rising in stages with an excursion to the summit of Meol-yr-Hydd (648m) if conditions are suitable. Mostly good underfoot on well defined trails with one or two steeper slopes which we will take gently. 

The slate mine landscape of North Wales was recently awarded UNESCO world heritage status. It is huge in scale, comprising stepped hillside workings, deep pits and cavernous underground chambers, massive cascading tips, ingenious water systems, and a range of industrial buildings some of which still survives. Of all the slate that was mined, only 10% was good enough to use. The remainder will rest for millennia covering the mountain sides along this walk. Slate contributed to rapid global urbanization and influenced building styles. From 1780 to 1940 this industry dominated world production of roofing slates, transforming both the environment and the communities who lived and worked here. Innovative transport systems linked quarries and processing sites with harbours and main-line railways. The narrow-gauge railway systems were adopted globally too.

NB If the weather is unsuitable for this higher level walk, an alternative walk around the route taken by Festiniog steam railway will be substituted, starting at the same time and location. In case of persistent heavy rain being forecast, the event may be cancelled. In this case a message will be sent out prior to 20:00 hours the previous evening.
