Ko Sukorn
Off the coast of Trang we can find with a very small island called Ko Sukorn, mother of four tinny
villages and one car, not per capita, per village! *giggle* (true fact).
Definetly the best option for people who needs to escape from the crowded island of Thailand, or their daily stress.
The long brunette beaches (dark sand), will be almost for those who choose this destination and will singly enjoy the spectacular sun rises and sets and of course the great hospitality the natives will bring.
An A+ for the small one :)

The way this place makes money is 3 fold, first you have to walk through a long line of souvenir shops before getting to the resturant/show building. second they give you too much time to eat, enough time to shop. and finally they make the food WAY TOO SPICY! and then charge you 4 times the market value for every drink that you are gonna need believe me.
I will recomend only the show. It is all dancing and very few lines of dialog. Sort of boring if you ask me but I'm not into the big stage productions. Only a few scenes with elephants.
The other cool thing about this place was the buildings were big and detailed. They have a Elephant palace. That makes it look like Elephants are Gods in Thailand.
Ko Samui is a very popular destination. Having it's own international airport, a mass of ferry connections and being so close to 500 hotels and guesthouses this place is useless for those who wants to explore untouch nature, relax or feel the inner peace.
Although if you are in the search of withe beaches, turquoise waters and all day sun where you can take pictures to brag infront of your friends and smile with their jealous faces this is your kind of place :).
There are also accomodations for every budget so you won't have to worry about that, but please do worry like always on make the reservations and any arragements with some time in advance or you will regreat it. 
Mysterious, old and primitive is the definition of Tarutao in Malay that should give you some clue about this island.
Ko Libong it's a large island located close to Thailand's southwest coast in Trang province. Not so visited, this island is cleaner than some other island around.
For the natives we can say they are polite, friendly and honest, also eco-minded.
Not so many tourists make it there but those that do realize how lucky they are. A cute place, very laid back where you will finally enjoy the life :) , dugongs can fin there too =P
For a long long time this Ko Lanta was a sometimes destination for backpackers, fullfilling the role of second fiddle to the main attraction for backpackers Ko Pha Ngan, but as always nobody could keep their mouths shut and they started to tell how great this island was.
Ko Tao has been over the years so many things for some many people, a pirate's hideout, a layover for the fishermen, a not so well kept backpacker's secret, even a prision!
