The map below shows the route of the tramway running from Porthmadog in the south-west, in an almost straight line north-east past the village of Croesor and into the valley beyond.  Approximately halfway along the tramway, the Welsh highland diverges to the north and Beddgelert.  The Festiniog Railway can be seen in the valley to the south of Croesor (the route shown is that following restoration).
