This is a noisy, crowded, colorful, exciting, irritating and smile-inducing city.
There are temples, ancient sites and other attractions to visit, as well as modern malls that have a kitschy yet sophisticated feel.
Bangkok can be overwhelming, but it's also a fascinating city that represents Southeast Asia's tension between the developed and developing worlds.
Bangkok also serves as a gateway to many other parts of Thailand.
From here, you can take a short flight to Phuket, Chiang Mai, Koh Samui and other popular destinations.
You can also board a train or bus for little money and visit national treasures like Ayutthaya , Lopburi and many other gems across the country.

The Chao Phraya, used by many boats, flows through the network of canals and also passes through the old town of Rattanakosin with the opulent Grand Palace and Wat Phra Kaeo temple.
Nearby is the Wat Pho temple with a huge reclining Buddha statue and across the Wat Arun river with its steep stairs and Khmer-style tower.
