Anyone who has ever been stuck in a Bangkok traffic jam has to love the BTS Skytrain. Both locals and travelers use it regularly. The sleek, elevated train whisks you from one end of town to the other in 25 minutes. There are two lines, the blue and the green. Siam is the interchange station that links the two lines. Trains run every three minutes 6 am-midnight. Fares range 15 baht-40 baht, depending on the distance you travel. Tickets can be purchased on a trip-by-trip basis, but it's much easier to buy a stored-value ticket (minimum of 100 baht). A map of BTS routes, one-day passes and various other discount cards are available at the ticket offices at each station. About the only downside to the Skytrain is that although most of the stations have escalators to the platforms, not all of them have escalators from the street level. So it's not recommended for people who have trouble navigating stairs. Phone 02-617-7340 for the hotline.
