BTS is Bangkok elevated rapid transit system, which is known as Skytrain. With BTS, you can go to the major areas in Bangkok without facing traffic jams. Currently BTS has 2 main lines: Sukhumvit line and Silom line.
Chit Lom Station is a BTS station on Sukhumvit line that is located on Phloen Chit Road, at Chit Lom Intersection, Pathumwan District.
Here is the map for the area around Chit Lom Station. I have got this map from BTS official website. The area map for the other BTS stations can be found here. To enlarge, click at the map.
What to see around BTS Chit Lom Station
Let’s look at the map.
The station is linked by skybridge to Central Chidlom (Exit 5), the shopping mall that has been opened since 1973. The mall is not as big as the malls that were built later, but you can find luxury products here. Most shops are compact, so you do not have to walk a lot to get what you want. From Central Chidlom, there is a bridge connecting you to Central Embassy, the most luxury shopping mall in Bangkok.
Besides shopping malls, from Chit Lom BTS Station, you can walk to Erawan Shrine or Than Toa Mahaprom, the popular shrine for Thais which is located at Ratchaprasong Intersection and recently I have seen more and more tourists there.
Hope this information helps
