Arriving in Porto for the first of what I’m sure will be many visits, I didn’t know what to expect. I’d heard more about Lisbon, the cosmopolitan capital of Portugal. But Porto has its own appeal, with a relaxed seaside vibe. As I soon discovered, it’s a dream destination for budget travelers who crave the sea, sun, great food and historic architecture. And in a city like Porto, a photographer will never run out of inspiration.
