What a surprisingly wonderful experience the Duoro Valley offers! I hadn’t heard of it before making the trip to Portugal and had assumed Lisbon and teh Algarve were the highlights. How wrong I was – the Duoro’s combination of vineyards, steep dramatic slopes and river views is one I can’t think of anywhere else in the world. When you add into the mix the unusual nature of the port wine to sample, then you have a real gem of an experience and, in my opinion, the highlight of Portugal.
