A coastal area in Thailand known as Maya Bay once had thousands of visitors each day after it appeared in the Hollywood movie The Beach.The film with Leonardo DiCaprio came out in 2000.Since then, visitors to the Southeast Asian country have taken boats to see the isolated beach.It is on an island called Phi Phi Leh and is surrounded by 100-meter-high cliffs.But the boats and tourists hurt the coral and chased away the fish.The water got dirty and the beach got polluted.So, although it hurt the economy, Thailand closed the beach in 2018.But this year, some visitors have been permitted back.Only 375 visitors are permitted at one time.Boats are restricted to one area.People cannot swim.But the corals and other life came back after three years of rest."The sharks have come back…and the water is clear again," said Yuthasak Supasorn, the governor of the Tourism Authority of Thailand.
