After Bala. turn left onto the A4212, this is a great road that has you winding past a picturesque landscape of forests and a lake.
After 18 miles or so take the right hand turning onto the B4391 towards Ffestiniog (Caution, this turning is not well signposted and is just after a bend)
Follow this road until to reach Ffestiniog then it’s a quick right/left onto the B4391/A496 and follow the signs for Harlech. Then it’s just a case of following the coast road into Barmouth for Fish and Chips.
