We had left the river Andarax at Alhabia the day before to join the river Nacimiento which would take us all the way to Abla and beyond. The deep rich layers of sediment washed down over millennia had created fertile ground alongside the riverbed that nourished a wide variety of crops but as we delved deeper upstream and away from the town the sides of the valley closed in and we were forced up on an old mule track with views down to the abandoned fincas and their hard won terraces.
