Porto's tumbling riverfront of colour and washing lines. Best before the tour groups.
The Ribeira is Porto's postcard, a stack of crooked, colour-washed houses tumbling down to the Douro riverfront below the great iron bridge, laundry strung between windows. It's a UNESCO-listed maze and the city's beating heart.
Yes, the soul of Porto; wander it early before the crowds and cross to Gaia for the view.
Yes — it's free to enter.
Come early morning, before the tour groups fill the narrow lanes and the riverside restaurants, which are pricier and touristier than the ones a few streets uphill.
