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.
Ratchadamri is a BTS station on Silom line that is located on Ratchadamri Road, near Ratchaprasong Intersection, Pathum Wan District.
Here is the map for the area around Ratchadamri 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 Ratchadamri Station
Let’s look at the map.
This area is one of the luxury areas in Bangkok. It is a quiet area that is full with luxury condominiums and hotels. When the train passes this station, you will see Royal Bangkok Sports Club (RBSC), big green scenery that can be seen from the hotels and condominiums around.
There is no shopping mall around the station, but Central World Shopping Mall, Gaysorn Shopping Centre, and Amarin Plaza are in walking distance. From the station, it takes only 10 minute-walk to reach these malls.
There are 3 shrines in this area: Erawan Shrine, Ganesha Shrine, and Trimurti Shrine. The first shrine is located at the corner of Ratchaprasong Intersection, while the other two shrines are located in front of Central World Shopping Mall.
Around 700 meters from the station is Lumpini park, a big park that local usually go for exercise in the morning and in the evening.
Hope this information helps. Enjoy traveling Bangkok!
