From Barmouth, head south over the Barmouth Toll Bridge -
its open to motorbikes and pedestrians but not cars.
When i went over it was £1.40 return (July 07).
Some nice views from the bridge and something different.
Surface of path to and from bridge is good (you do not
need a trail bike) and once on bridge be sure to ride
slowly as its a sleeper bridge and not very wide for you
Once on the opposite side of the river, turn right onto the
A493 toward Tywyn (away from Dolgellau). Some nice views
from here over toward Barmouth and as far up to Portmerion.
Follow the road to the next major junction, with the B4405
