Lovely steep dual carriageway with minimum traffic from the valley up to the sennybridge military training area. Only on Welsh mountain roads would you find this

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.

Spend a few moments on the bridge over the River Sawdde river to take in the view. A great bird watching spot, if you are patient or lucky enough you may see Sandpipers, Dipper or Kingfisher here.
