Phi Phi Island
Two hours with boat from Phuket is the Island Phi Phi.
Phi Phi Island is split in two Islands, Phi Phi Don (where you can live) and Phi Phi Lee (now famous from the movie “The Beach”).
Here you can live in bungalows directly at the beach. There are coral reeves very near and it feels like swimming in a giant aquarium with a lot of colorful fish below.
