Temples, street life and the locals' prioritization of fun define Bangkok. Get amazing, real-deal Thai food on the street, take a boat trip, and bear witness to the boundary-pushing nightlife.
Cable cars, Fisherman's Wharf, and of course, that famous bridge.... San Francisco beckons visitors with a mild climate, world-class dining and culture, and of course, that famous rolling fog.
To visit Barcelona is to embrace both the past and the future. There is much to do and see in this cosmopolitan capital of Catalonia, from medieval structures to beaches to UNESCO Heritage Sites by Antoni Gaudí and Lluís Doménech i Montaner.
