The national park of the Similan Islands (เกาะสิมิลัน) is in southern Thailand, 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 UNESCO World Heritage Site.

The 2004 tsunami left the islands and the underwater landscape almost unharmed, since the waters are very deep around the islands.

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.

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.

Getting there

There are several dive trips going to the Similans 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.

From Phuket

Some diving liveaboard trips depart from Chalong or Patong. Most departures actually leave from Tap Lamu near Khao Lak but focus on the Phuket area, with offices in Phuket and pickups from major beaches:

Traveling around

There are tours leaving from Khao Lak that offer diving and snorkeling tours. In addition, once on the islands there is the option of using the Marine Park boats for transit between the islands. This is not totally reliable, but is a less expensive alternative.

See

Incredible marine life, great scenery, white sand beaches.

Things to do

The Similan Islands are home to some of the best diving sites in the world. They are also home to great snorkeling, bird watching and sunbathing.

Sleep

Lodging

There are both tents and bungalows available for rent. These are only available through the National Park headquarters in Taplamu or through agents.

Camping

Tents are available for rent. In addition, on Island #8 you can rent space and put up your own tent.

Safety

See the Stay safe section of the Scuba diving article for diving safety tips. Be aware that the islands are closed from mid-May to Early November of each year. Tour operators going to the islands during the closed times are not only risking your your comfort but safety.

Fees/Permits

The National Park fee is 400 baht/day (children 100 baht). For Thai citizens the fee is 40 baht, children 20 baht.

Diving fee is an additional 200 baht/day regardless of passport.
