Metro in Bangkok Thailand: Complete Guide to BTS and MRT

Bangkok’s metro system has grown rapidly since the launch of the BTS Skytrain in 1999, with the MRT Subway following in 2004. Today, the system includes multiple interconnected lines, including the newly inaugurated Yellow Line and Red Line, providing extensive coverage across the city for both locals and tourists.

Although getting around Bangkok has become much easier thanks to these train networks, it is helpful to know the different lines and ticketing systems.

1. Understanding the Bangkok Metro Network

Inaugurated in 1999, the Bangkok metro has continued to expand to cover the main areas of the city. It's made of :

• The BTS Sky Train: aerial metro, made up of 2 lines (green and dark blue) which intersect in Siam. It crosses the city from north to southeast.
• The MRT Subway underground metro which has 2 lines (blue and purple). It travels through Bangkok from east to west.

The two networks are interconnected and form a rail loop, allowing easy access to all important areas: shopping centers, tourist attractions, business districts, etc. The metro map is very simple with a color code for each line. You will find detailed maps at all stations. Air-conditioned trains run frequently with little waiting during peak hours.

Note that the recently inaugurated MRT yellow line is not part of the same network. Tickets are therefore not valid from one network to another.

The public transportation system map in Bangkok is usually distributed for free at airports. You can find them at information desks. There are also self-service public display stands. Please click in or save the map right below for better view:

Otherwise, you can use the map on your phone by searching for 'Mmap Bangkok' on Google.

2. How to use the BTS Skytrain in Bangkok?

The BTS Skytrain is one of the most convenient ways to get around Bangkok. This aerial metro network allows you to travel above the city's heavy traffic and offers breathtaking views. There are two lines, the green Sukhumvit line and the dark green Silom line, which intersect at Siam Square.

If you want to go to large shopping malls, department stores, or entertainment complexes, BTS is ideal. Its resorts are located close to most tourist attractions (Siam, Central World, MBK,..), making travel easier. This will help you avoid the omnipresent traffic jams in the Thai capital.

Although relatively expensive by Asian standards, the BTS Skytrain remains an interesting option for tourists coming from Europe or North America. For most short journeys, it will be cheaper to take the BTS for 3 or 4 people than to book a taxi. It's a good way to explore Bangkok efficiently and comfortably.

• What are the BTS timetables?

The BTS Skytrain operates daily and offers regular service during operating hours. Frequencies are increased during peak hours in the morning and evening. Unlike subways in other major cities, the BTS does not run very late. Remember to check the departure times of the last train so as not to find yourself stuck.

The first departures take place at 5:15 a.m. on the Sukhumvit green line and at 5:30 a.m. on the dark green Silom line. The latest departures vary between midnight and 12:30 a.m. depending on the line and direction.

For the exact timetable, check out BTS's website here: Timetable (bts.co.th)

Allow enough time to change lines if necessary, especially at the Siam transfer station. The precise timetables are displayed in each station.

• How much does a BTS ticket cost? How to buy it? 

Bangkok's BTS (Skytrain) offers variable fares depending on the length of the journey. The price of a single ticket varies from 17 to 62 baht ($0.4 to $1.7). You can calculate the exact price of your route on the interactive BTS map. An unlimited-day ticket costs 150 baht ($4).

The Rabbit Card is recommended to save time by avoiding queues at the ticket counters. Usable for the BTS, buses, in certain restaurants and stores, it also offers discounts. You can purchase it before your trip and collect it at the airport or CentralWorld. Only this card allows you to pay with a bank card, otherwise only the purchase of tickets is possible.

3. The MRT, the underground alternative to exploring Bangkok

The MRT subway is a cheaper alternative to the BTS. It covers more areas in Bangkok, including many tourist attractions. The MRT has two lines: the blue and the purple.

• The blue line is the most popular. It connects the main commercial, residential, and cultural districts (China Town or Chatuchak Weekend Market)
• The purple line mainly serves the outer suburbs. 

The MRT includes 35 stations on the Blue Line and 16 on the Purple Line. The new Yellow Line is not integrated into the MRT network and requires a separate ticket.

6. Tips for Rush Hour in Bangkok

• The BTS and MRT in Bangkok are similar to major city metros like New York's. Avoid rush hours (7am-9am and 4pm-7pm) if traveling with a group or kids, as they get very crowded.
• The Airport Rail Link is efficient for getting to and from the airport, with lifts and stairways for luggage. However, it's better to take a taxi or Grab if you have luggage for a group.
• Expect the BTS and MRT to be packed during rush hours. It’s manageable, but you may need to wait for the next train and will likely stand most of the time.
• The BTS doesn’t connect directly to the airport. Use the Airport Rail Link and transfer to the BTS or MRT. With luggage, especially for a group, a minivan or taxi is more convenient.
• Crowds can vary; rush hours are particularly busy, but at other times, trains might be less packed. Plan accordingly for a smoother experience.
