5Porto, Portugal

While Lisbon is Portugal’s capital and most well-known city, Porto is a hidden gem that shouldn’t be overlooked.

Located in the northern part of the country, Porto is famous for its historic old town, Ribeira, a UNESCO World Heritage site, which sits along the banks of the Douro River. The city is also the birthplace of port wine, and you can visit the many wine cellars that line the river to sample this delicious fortified wine. Porto’s vibrant culture, stunning architecture, and warm hospitality make it a must-visit destination.
