Sunset on Railay Beach in Thailand. Every evening the sky and the Andaman sea present a show with their own interpretation of the sunset. If you are lucky and visit the Krabi province when the conditions are right, you can swim in this beach with the bio-luminescent plankton, the small creatures that give you a slightly tingling sensation all over your body. At night, you just lie in the water, splashing it and moving around and you will see it just glow and sparkle, like in a dream.
