One of the most beautiful festivals in Thailand takes place on the full moon night of the 12th lunar month. It is known in Thai as Loy Krathong, but is sometimes referred to as the Festival of Lights. The next one will take place nationwide on 10th November 2011. For many years I have been floating my krathong, a kind of bowl made from banana plants, on my local river in Samut Prakan. This year I was really happy to get an invitation to take part in the âYee Peng Festivalâ in Chiang Mai.
