Built in 1913 the Rhandirmwyn Bridge links the two sides of the Towy valley by this rivetted girder road bridge. On the southern side you'll find the Towy Bridge Inn, a lovely riverside pub.

Officially, Bethlehem is the end of the Beacon Way... but absolutely no sign is placed to mark the arrival. It's a very small village (even no pubs :-)), with some beautiful views, especially around the old church.

Recently dressed with slate. I would no longer recommend road tyres through here. Something a bit wider recommended!
