Thailand at night can be spectacular. The bustling night markets with strings of lights trimming the food stalls make for a night photographers dream.
On special events, Songkran, Loi Krathong, King's Birthday, many buildings will also be lit using bulbs of many colours. Perhaps the most spectacular is on the King's Birthday when Sanam Luang and the Grand Palace in Bangkok is floodlit in honour of the King. There is also a free firework display that's not to be missed.
