At the quay, you'll have some free time to enjoy lunch. This is a great opportunity to sample the local cuisine of the Douro Valley. The food here is as rich and varied as the landscape itself. From hearty meat dishes like Posta Mirandesa, a thick cut of veal grilled to perfection, to fresh river fish like the shad, served with a sauce of olive oil, garlic, and vinegar.

Don't forget to try the local cheeses, like the creamy Serra da Estrela, and the olive oil made from local olives. The gastronomy of the Douro Valley is a testament to the region's agricultural bounty. As you enjoy your meal, consider how the food, like the wine, is a product of this unique landscape. The flavors you're experiencing are the result of centuries of culinary tradition, shaped by the land and the seasons. As you savor each bite, remember that you're not just tasting food; you're tasting the essence of the Douro Valley, distilled into a meal.
