18 Life-Changing Vacations for Couples

Porto, Portugal

Porto is a waterfront merchant city that transports you to an earlier time with its cobble-stoned streets, baroque churches, and prevalence of family-owned businesses and port factories, the region’s most famous export. In the nearby Duoro Valley, you can visit the vineyards where the wine has been produced for 2,000 years, sample the wine, and participate in some harvesting practices like stomping on the grapes. In a city infused with the culture of wine making and drinking, you and your significant other can get tipsy on the energy alone.
