While not as extensive as Bangkok's bus system, the Metro and the Skytrain are by far the most convenient and affordable ways of getting around the bustling city. The Metro covers a rather smaller section of the city but is incredibly convenient for those staying in that vicinity. Whereas for the Skytrain, the elevated BTS covers a much larger area and even has a link connecting to the Suvarnabhumi Airport. For travellers who look forward to taking the Metro or Skytrain multiple times a day, preferably more than three rides in a single day, it is worth buying a one-day pass that allows multiple rides on the date of issue.
