One of our must-do’s while in Porto was taking a trip to the Douro Valley. You have many options for getting there – renting a car, taking part in a tour that begins in Porto, or taking the train. If you know Koen and me, we love taking the train (hence the Trans-Siberian Express vacation we took two years ago from Moscow and ending in Beijing). So any opportunity for a long train ride – we’re in! Plus that means no one has to drive and we’re both able to enjoy the tasting.
