After a buffet breakfast on board, we will set off to explore Porto on an optional guided tour. One of the oldest cities in Europe, whose historic centre is classed as a world heritage site by UNESCO: unspoilt old quarters, a maze of winding narrow streets, arcaded houses, superb churches… But above all, Porto is Port wine. Among the wine properties that extend as far as the eye can see along the Duoro in Vila Nova de Gaia, we will visit a famous cellar where this exceptional wine slowly ages in the greatest secrecy. Tasting of the “precious nectar”*. Back on board for lunch, followed by a free afternoon to discover Porto at your own pace, or ask to be transferred downtown by rabello. Return on board for dinner and a fado evening.
