Bucle del castillo de Usk

Immediate steep incline from Llanbadoc Island to the top of the bluff above Usk. A pleasant flat section follows, proceeded by a muddy downhill track. Flat through town, up the steps by the old railway bridge and then flat again down the riverside footpath. Then a long but gentle uphill section towards Usk Castle, before dropping back down into Usk, over the bridge and completing the loop.
