Portugal has enticed more and more travelers in recent years, and no wonder -- it’s affordable, it’s adventurous, and it’s absolutely gorgeous. Most first-time visitors focus on the capital, Lisbon, so for better or worse, other areas have remained somewhat sheltered. That’s changing now. Lisbon continues to be fantastic (and still a relatively under-visited European city) but if you’re thinking about traveling to Portugal, you should be thinking about Porto.
