Bangkok is a fast-paced, densely populated capital city that offers tourism ranging from the very highest end to rock-bottom cheap. In the backpacker mecca of Khao San Road, you can find a crash pad for US$20, while in the Chidlom-Ploenchit District, luxury brands reign. Meals range from quick $2 bites off a street vendor cart (if you dare) to the nine-course Manohra Dinner Cruise. And popular tourist activities range from visiting the floating market to watching youths go hand to hand in a (highly stylized) Muay Thai match.

The city has countless temples, gardens, and other landmarks, but two that you can't miss are the Temple of the Emerald Buddha and the Grand Palace—home to Thailand's beloved king. Another great photo op is the Temple of the Reclining Buddha... and if you still want more temple photo ops, visit Wat Trimitr, home of the 10,000-pound Golden Buddha.
