Bangkok map and getting around via bts or mrt

there are 2 types train stations in bangkok - BTS (this is common around bangkok) and MRT

The BTS is undoubtedly the swiftest way to get around, and can whisk you right where you want to be in no time at all. It's a cheap, smooth, cool, clean, fast and scenic way to enjoy Bangkok. Major shopping malls, Chatuchak Weekend Market, all Sukhumvit Road's attractions, and even the riverside are accessible by Skytrain.

While the Silom line runs west to south, the Sukhumvit line runs north to east (see the BTS route guide). So, if you're new to Bangkok, it's a great way to find your way around and see a large part of what the city has to offer. Note that Service runs between 06:30 and midnight, and the trains can be packed during peak hours (07:00 - 09:00 and 16:00 - 19:00).

Fares and Skytrain Passes :

if you travel bangkok every year, we strongly recommend purchase of the BTS RABBIT card (B100 for fare + 50 baht card deposit refundable) so no need to queue and last for 5 years.

  

The BTS Rabbit cards are used to access all stations. Fares start at 15 baht per one stop. A one-day pass may be a good option for those planning to do a lot of hopping on and off for one full day. But if you plan to be in Bangkok for a while, it might be a good idea to buy the BTS Smart Pass.
