Porto’s charms have been consistent for centuries, due to its UNESCO heritage Old Town and world-famous Portuguese wine trade. The ocean cruise port of Leixões is actually in neighboring Matosinhos. Most cruise passengers do excursions to Porto to check out the bustling café scene on both sides of the Douro River, as well as the historic center of Ribeira on the southern hillside. Those who just want a mellow beach day remain in Matosinhos.
