Great view of the Mawddach Estaury and the mountains beyond, including Cadair Idris. The bridge is 850m long and can be windy in the middle.

A series of five carved chairs around Harlech. Great idea to get the children outside to find them all, with scan codes at each one for more details. I believe this is number 3 over looking Harlech Castle.

Card payments are accepted. The bridge is open to cyclists and walkers 24/7. There is a slot for the toll in the door outside of operating hours.

Why not stop by the Cross Foxes Pub for the night? It's a great location by the Traws Eryri route. The pub has bunk beds and free breakfast with optional english breakfast on the menu
