Maya Bay, Thailand was closed for two month of period and end up being closed again on September after one day openning it doors, the news can be found here. The retraction of announcement for openning is doors are hindered by the overwhelming polution due to high density of irresponsible tourist. Thus the beach was closed for any tourism to allow marine life and coral restoration take place.
Up until recently, the beach have been seen that sharks are returning to the beach due to its recovery effort. Soon the beach will be returned to its original ecology and it will once be open to public.
However just because it was recover does not mean you could once again sully it. Please behave properly in effort to conserve the marine life.
