Porto river cruises, Portugal

What's great about Porto river cruises?

Portugal’s second-largest city is sprawled over a hillside, overlooking the Atlantic Ocean and the winding Douro River. It’s a mass of pretty, terracotta-roofed buildings and winding streets. It has a big claim to fame, too – it’s the historical home of port. Tasting the drink is a must while you’re here, and you’ll find centuries-old wineries tucked among the area’s parks and beaches.

• Dine on gourmet food, mooch around arty boutiques and catch street entertainers at the quayside.

• Slot in some sightseeing in the old town, Ribeira. It’s earned UNESCO status, thanks to its ornate tiled churches and antique bookshops.

• Sip vintage wine during a tasting session in one of the wine estates in Quinta de Vargellas. It's known as one of the best spots to pick up fine port.
