Ffestiniog Railway, Snowdonia. The Ffestiniog winds its way from Porthmadog through more than 13 miles of stunning countryside.
Waterfalls cascade and streams froth down mossy rock sides. Swathes of deep green grass soar on one side while valleys dip spectacularly on the other, affording the chance to look down on treetops far below.
Sharp bends in the line offer splendid views of the engine as it chugs onward and upward to Blaenau Ffestiniog, where there’s a chance to travel on an even smaller train into a former slate mine.
The slate-waste landscape at the top of the line makes a fascinating contrast with the natural beauties below.
