The Racha (or Raya) the twin islands, some 12 km south of Phuket, are best known as excellent diving and snorkelling daytrip destinations. Known for their crystal clear blue waters these islands have been an almost exclusive paradise for divers for years. 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 Sunset Beach. The water is clear and perfect for snorkelling, though the bay gets quite busy with visiting boats in the afternoons. The other large bay, Ao Siam, is a pretty place where lonely strolls in solitude are possible. Racha Noi is uninhabited and has no services or accommodation, but there’s some great diving in the area.
