The main access route to Blaenau Ffestiniog is the A470 road running north to Llandudno and south to Dolgellau and beyond. The A496 runs south to the coastal resorts of Harlech and Barmouth and connects with the A487 towards Porthmadog and the Llŷn Peninsula. Immediately to the north of the town, the A470 climbs steeply to the Crimea Pass and meets the A5 at Betws-y-Coed, giving access to Llangollen, Wrexham and Shrewsbury in the east and Bangor and Holyhead in the west.
