Have you heard about free walking guided tours? I love those. You get to see many of a city's famous and locally famous spots. Usually, an experienced local shows you around, and you see many of their favored places. Sometimes, it is a great market, an incredible local cuisine restaurant, or just a favorite rooftop bar with good service, excellent drinks, and a one-of-a-kind view. You get to experience the city, not only the tourist attractions. I love it!
