In the Center 0f Chaweng, there is a lake and this is the venue is the ideal place to see and participate in the Loy Krathong to see the people float their flower boats with wishes to the Water Goddess, they are for the following reasons:
You put a coin on the boat and send it to Water Goddess, as an offering One for good luck, One for applogise what they have done with the great river and this has been done for over 200 years and to keep the custom for future generation.
It was a spectular event it was not noisey just serene and wonderful. There was entertainment and food laid on for afterwards if you wanted.
I will stop there and let the photographs do the talking
With Thank to my Thai friend Tent for the info on reasons for Loy Krathong
