White Sand Beach

Hat Sai Khao (White Sand Beach) is Koh Chang's longest and most visited beach at about 3 km, fronted by gentle Gulf of Thailand water and backed by a strip of guesthouses, restaurants, and bars that manages to remain relatively low-key despite being the island's commercial centre. The beach earned its name from genuinely pale, fine-grained sand — notably whiter than most beaches in the Gulf.

Koh Chang sits in the Trat province near the Cambodian border, well to the east of the main tourist circuits. This eastern Gulf location gives the island a different character to Samui or Hua Hin — more authentically Thai in its slower pace, with jungle-covered mountains rising sharply behind the beachfront development and a national park designation limiting sprawl.

The water at White Sand Beach is calm and shallow, ideal for families and casual swimmers. The coral reef off the southern rocks provides basic snorkelling. The beach is at its best from November through April; from May onwards, a combination of rain and occasional jellyfish makes it less appealing, though the lush jungle and waterfalls in the island's interior remain accessible year-round.
