Information on Similan Islands from the Wikipedia

information about getting to the Similan Islands from Khao Lak....

The national park of the Similan Islands 50 kilometers west of Khao Lak. It is considered the best place in Thailand for divers.

Understand
The park covers 140 square kilometers in total, 14 of those being land in the shape of an archipelago consisting of nine islands. They are Ko Bon, Ko Bayu, Ko Similan, Ko Payu, Ko Miang (two adjoining islands), Ko Payan, Ko Payang, and Ko Huyong. For simplicity they are often referred to by their number instead - 1 through 9 starting from the south. Recently, the park was expanded to include the two remote islands Ko Bon and Ko Tachai, but since "Sembilan" is Malay for "nine" this doesn't seem to stick in people's minds and those are not visited as often as the original nine.

History
The islands were created by upwellings of hot magma during the Tertiary-Cretaceous period some 65 million years ago, then smoothed by glacial ice and the erosion by the sea. The coral reefs are about 5000 years old and hence the oldest in Thailand. In 1982, the national park was established and now it is scheduled to become a World Heritage.
The 2004 tsunami left the islands and the underwater landscape almost unharmed, since the waters are very deep around the islands.
Landscape
The nine granite islands are postcard perfect images of paradise, covered in tropical jungle and equipped with beaches of chalk-white sand. As if this was not enough, the views under the water surface are even more impressive - this is the best dive site in Thailand. Skin-Diver Magazine has acclaimed the Similans to be one of the ten most beautiful places in the world.

Flora and fauna
There is an enormous diversity in species - both in fish and corals. The visibility is the best you will find in Thailand. You will see plenty of colorful fish such as lionfish and clownfish (Nemo), and if you're lucky you may spot a bigger one like a manta or even a whale shark.
On Ko Huyong Thai Marines run a turtle breeding facility, but access to the island is limited.
Climate
High season in the Similans is from December until April, when the monsoon stays far away. The best period to visit is March, when the winds are calm and the water clear. The national park is closed from May 16 to November 15.

Get in
There are several dive trips going to the Similan from Phuket and some from Khao Lak. Both day trips and live aboard cruises are available. Dedicated cruises where your boat picks your group up from your destination and cruises around usually start at 4 days and 4 nights in length. Many shorter trips are available, often with operators who have a large vessel on the islands over summer and who do regular transfers using smaller speed boats.
Note that there is a national park entry fee of 400 baht per traveller and a further daily usage fee of 200 baht per diver per day. Most boats do not include this in their quoted price. It is paid to your dive operator before the trip.

A helpful list of the EU's banned arilines...

It was brought up by that recent crash off the Comoros Islands.

2 years ago we had a bad plane crash here. It was from the only banned airline from Thailand. Using untrained pilots and landing against the advice of the flight tower in extremely bad weather.

http://ec.europa.eu/transport/air-ban/list_en.htm

However, flying in Indonesia is a concern. Not one Indonesian airline is allowed to enter EU airspace. At all.

However all US based airlines are allowed to fly.

Economic Solutions to Overfishing?

Here are Wicked Diving we are always looking for ways to get reduce the amount of fishing going on - particularly right here! The impact from overfishing is obvious on almost dive site in the world. Locally we can see the results. On the Similan Islands there is a certain amount of protection and the government enforces the no-fishing rule (sometimes)

However the greatest way to make changes is to make economic changes. AS areas are overfished - there is less money in the act. To replace that with something that pays more and is easier is definitely a great option.

An article In Dive Magazine Uk talks about the Shark Diving in Fiji on destroyed reefs. They not only generate a large amount of income - but they are a famous destination for those wanting to experience Sharks. Personally I am not a fan of feeding fish - but I am a fan of showing how there are many ways to generate income in small communities that create a viable alternative to fishing.

http://www.divemagazine.co.uk/news/article.asp?uan=5243

Great Alternatives are artifical reefs - either manmade of through shipwrecks. Here in Khao Lak, the local dives are done from converted fishing longtails. The drivers earn much more per day than at fishing, and do less work. We are working on some other options in the near future that will offer more alternatives to these fisherman.
