Sukhumvit stretches for kilometers and is split into numbered soi (side streets), each with its own character — from the malls near Siam to the nightlife around Nana and the quieter, leafier stretches further out.
The BTS Skytrain runs the length of Sukhumvit, making it one of the easiest areas in the city to navigate without a car.
