Koh Raya Islands (or Racha Islands) are best known as among the best diving and snorkeling destinations in Thailand. Located some 12 km south of Phuket, Koh Raya Noi is uninhabited, but there’s some great diving in the area. Koh Raya Yai has several bungalows and resorts if you want to stay on the island for a day or more.
Racha Yai reveals itself in splendid fashion, with most arrivals landing onto a strip of fine white sand tucked deep into the long, U-shaped main bay, called Ao Tawan Tok or Ao Bungalow. The waters are clear and excellent for snorkelling, though the bay gets quite busy with visiting boats in the afternoons. Racha Yai is home to The Racha, a splendid getaway resort. The other large bay, Ao Siam, is a pretty place that’s great for peaceful strolls.
