Between Phuket and Krabi, in the middle of Phang Nga Bay, lie the islands of Koh Yao Noi and Koh Yao Yai. The islands have escaped development until recently and as a result you will find life here a good deal quieter than either Phuket or Krabi with plenty of opportunity to relax peacefully.
The most popular of the two islands is Koh Yao Noi and this is where you will find hotels like the Koyao Island Resort and the luxurious Six Senses Hideaway. However its bigger sister, Koh Yao Yai, has a more rustic feel to it and is great for those looking to get away from it all - here you will find the Glow Elixir. Both islands can be reached by ferry, or speedboat, from Phuket.
