Bangkok Metro and SkyTrain
The Metropolitan Rapid Transit (MRT)
We picked our hostel because it was within walking distance from a MRT stop, which we read was the best way to get around Bangkok. The MRT was extremely easy to use, convenient, and very very clean. Everything was in Thai as well as English, at the entrance of the station there was always a Route map of the MRT Line as well as a Locality map with entrance and exits of the station.
The inside of the MRT trains was very clean and well lit, with lots of space for people to stand and special priority seating that people actually respected. There were advertisements in both english and Thai, as well as maps of the MRT and SkyTrain.
There are two types of tickets that you can purchase on the metro, a single journey token or a card that you can add value to. The price for the single journey token depends on what station you get on and off at. There are different types of cards you can purchase, with discount for students and different age groups. You can also buy a 24 hour pass for 120baht or a three day pass for 230 baht.
Bangkok Mass Transit (BTS)/ SkyTrains
The Bangkok Mass Transit (BTS) is the transit agency that runs the SkyTrains in Bangkok, which is separate from the MRT. BTS opened in 1999 and currently only has two lines, the Silom Line which goes west to south and the Sukhumvit Line which goes north to east. There is a planned airport rail link to the Suvarnabhumi Airport and for the Don Mueang Airport.
To get from the MRT underground to the SkyTrain you had to take a number of escalators. There were very clear way finding signs that were color coded and in both Thai and English. The stations were always open air and very clean, with clocks and maps everywhere.
You have to buy a separate ticket if you want to used the SkyTrain. There are two types of tickets you can purchase for the SkyTrain, a single journey for 15-52 baht depending on zones crossed, and a day pass for 140 baht. On the back of the day passes are a map of the stations.
