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.
Phra Khanong is a BTS station on Sukhumvit line that is located near Sukhumvit Soi 71, on Sukhumvit Road, Khlong Toei District.
Here is the map for the area around Phra Khanong BTS 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 Phra Khanong Station
Let’s look at the map.
You will see that there is nothing much to see around this station. Phra Khanong is a residential area, not a business area. In the past, this area is a place where middle-class people live, but nowadays I have seen some condos popping up in this area and some expats choose to live there.
There is a community mall named W district, which is located in a walking distance from the station. If you want to see how local market looks like, you can visit Phra Khanong market.
Hope this information helps. Enjoy traveling Bangkok!
