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.
On Nut BTS is a BTS station on Sukhumvit line that is located near Sukhumvit Soi 79, on Sukhumvit Road, Khlong Toei District.
Here is the map for the area around On Nut 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 On Nut Station
Let’s look at the map.
You will see that this area is full with condominium. Yes, this area is a residential area and there is not so much thing to see at this station.
I have been living in this area for more than 20 years. I could say that this area has been dramatically changed since the arriving of BTS. It was a living area of middle class people, but nowadays I see many condominium and many expats and tourists here.
The station has a skybridge connecting to Tesco Lotus Supermarket. Opposite to this supermarket is Onnut night market, a popular shopping place in this area. Some stalls in this market sell clothing, shoes, handbags, and accessories, while some stalls sell food and drink. There is a beer bar at the back of the market. This market is a meeting place for local people after work and also tourists.
Hope this information helps. Enjoy traveling Bangkok!
