4Maya Bay, Thailand

Located on the island of Koh Phi Phi Leh, Maya Bay shot to fame after the movie The Beach was filmed here. This gorgeous bay, surrounded by cliffs and crystal-clear water, became a tourist must-visit destination. Unfortunately, many visitors damaged the coral reefs and surrounding ecosystems.
The Thai government had to close the beach for several years to allow nature to recover. Though it has reopened with restrictions, Maya Bay is still struggling to regain its former beauty.
