MRT (Metropolitan Rapid Transit) is Bangkok rapid transit system, which is known as subway. Currently MRT provides service only one line (Blue line) which has 18 stations between Hua Lamphong and Bang Sue.
Ratchadaphisek MRT station is a station that is located on Ratchadaphisek Road, near Soi Chokchai Ruammit.
What to see around Ratchadaphisek MRT Station
For me, this is another station that does not have things to see. Around the station is a dense residential area. There are condominiums and office towers.
Hope this information helps. Enjoy traveling Bangkok!
