Is this the most beautiful beach in Thailand?

What’s the best beach in Thailand? It’s a difficult call. Some people praise the picture-postcard perfect beaches of Phi Phi Island. Others rave about the low-key charms of Ko Tao (Tao Island), just off the bigger and brasher Ko Samui. But old Thailand hands swear by Ko Similan, in the Similan Islands National Marine Park off the Andaman Coast, with rudimentary facilities but great snorkelling and diving, and much frequented by discerning Thais.
Off the west coast of Thailand, Phuket has it all – from glitzy resorts to the seedy bars of Patong Beach. But for those seeking a little quietude, the beaches around Khao Lak, on  Andaman Coast of Thailand, are a little-known and supremely relaxing getaway. Less than an hour by road north of Phuket’s International Airport, Khao Lak could be light years away from Phuket in terms of traditional values. Right on the beach near Khao Lak village, the new Nang Thang Bay Resort offers four-star comforts at bargain-basement prices.
Southeast of Bangkok, Ko Chang Island is the biggest island in the Ko Chang National Marine Park, offshore from the town of Trat. Its west coast beaches are now undergoing rapid development, but the holidayscape is decidedly more restrained than on Phuket or Ko Samui. Some say that Ko Chang is a little boring and a long way from anywhere, but this is certain to change as the island’s charms become better-known.
