Second best for Christmas in Bangkok is Siam Paragon located next to the central Siam Skytrain Station. Siam Paragon is Bangkok’s luxury mega mall. The tree at Siam Paragon lights up from the inside – blue, green, red, white – it has remained the same the past 3 years. Next to it is a walkway lit up with decorated arches and surrounded by fountains. The images below are from 2011.
