A Walk on the Wine Side, National Geographic Traveler

Port requires patience – you must wait 20 years to open a vintage, but then you have to hurry up and drink it within 24 hours.

That’s one thing I learned on a week-long walk through the vineyards of Portugal’s Douro Valley. This spectacularly unspoiled corner of northern Portugal also produces some knock-out red wines. Since drinking and driving were out, we figured the best way to experience Porto and the Douro region was to walk.

Thanks to Inn Travel, we didn’t put a foot wrong.
