Truth be told, Bangkok's subway system is pretty small. Just one line and 18 stops serve a small part of central Bangkok. Though it's not as vast as the subway systems in New York, Paris, Beijing or even Boston for that matter, it's still a great transport option if you're visiting the capital. It's relatively new, spotlessly clean, safe, comfortable and much faster than getting around the city by car or bus. And though it isn't comprehensive, you can take the subway to a number of important tourist destinations. Find out what you need to know about Bangkok's subway.
