This is the island I’ve been looking for all of my life. No markets, no vendors, no traffic, no noise and hardly any people. There are only a handful of places to stay and one expensive resort. This is what I remember Thailand to be 15 years ago. Just locals and a few tourist. I love it here. There is nothing to do but relax and listen to the sounds of nature. Koh (means island) Yao Yai is an Island in Phang Nga Bay. It is the largest island in the Ko Yao Archipelago. . The population is 3000.
