Bangkok opened its elevated Skytrain service several years ago to great acclaim. The two lines reach a surprising number of hotels, sights, and shopping districts in the city, as if the Skytrain was constructed to serve the needs of the tourist rather than the locals who continue to favor the much cheap
er buses. Skytrain maps are available all over town. The main routes and destinations are the river, hotels along Silom Road, the Patpong entertainment district, hotels along Sukhumvit Road, the shopping centers near Siam Square, and the Jatujak Weekend Market. You can either buy stored-value tickets (minimum 200 BHT) or purchase a per-ride ticket from vending machines. Stored-value tickets and change for the vending machines are available at the station booths. Plans are now in place to extend the Skytrain 
service in future years.BTS Skytrain official website in English.
