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.

A beautiful section the Cycle Across the Beacons route, with the road passing to the South of the Usk reservoir and crossing the River Usk itself.

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.
