Coimbra gets first dibs today, with time to poke around its old university streets, tiled corners and river views your way before Porto takes over. On arrival, follow your Local Guide through a city that knows how to make an entrance, from Douro bridges and busy port views to the UNESCO-listed Ribeira Quarter stacked along the river. This evening, choose your own Porto plot. Add a Choice Experience and head underground in Gaia to a cool, oak-scented wine cellar for the lowdown on this iconic sip, ending with a tasting of those rich, velvety flavours. Or keep things social with a Choice Experience dinner packed with Portuguese favourites and good company.
