The Douro River winds through the mountains and cliffs of northern Portugal, creating a valley with rich conditions for vineyards. It’s here that grapes for Port are grown and here that you’ll want to explore some of the oldest wineries. The great city of Porto
is itself a UNESCO World Heritage Site, dating back 2,000 years. Its architecture spans the ages and styles of Romanesque, Gothic, Renaissance, Baroque, neoclassical, and modern design, and the streets and local culture are alive with artsy enclaves and vibrant nightlife.
