One of the most beautiful island in Thailand, there were very little tourist and the traffic is like a stand still.
Note: Coming from Cambodia by land
If you have not prepare a Thai VISA, the Cambodian immigration will ask you to get it from Thai immigration. It's about 150m away. Once you have obtain the Thai VISA only then the Cambodian Immigration will allow you to depart.
We took land transport and there was quite a waiting time.
