Similan Island






The Similan Islands are a group of nine islands about 100kms northwest of Phuket. The area has been designated the Similan Marine National Park. The Similans are famed for their spectacular underwater scenery and marine life, and is regarded as one of the top ten dive spots in the world. The islands are completely undeveloped, except for Koh Miang, where the park headquarters, a visitors centre and some accommodation are located. There is also a royal residence on Koh Miang.

The name “Similan” is derived from the Malay sembilan meaning “nine”. Each of the Similan Islands has a number as well as a name. Thais often refer to the islands just by their number, so Koh Miang is Koh Si, meaning “island number four”. From north to south these are as follows:

9. Koh Ba-Ngu
8. Koh Similan
7. Koh Payu
4., 5. & 6. Koh Miang (actually two islands, with Hin Pousar often designated as no.6)
3. Koh Payan
2. Koh Payang
1. Koh Hu Yong

The beaches are pristine and although the scenery above water is not as dramatic as the limestone islands in Phang Nga Bay, the smooth granitic rock formations and scattered boulders, together with the crystal clear sea, make up for it.

The best time to visit the Similans is from November to April. This is when the weather is at its best and the water visibility is clearest. Plenty of dive-boats visit the island on day-trips and liveaboards from Phuket and Khao Lak during this time. June marks the start of the rainy season when the national park effectively closes, though there are still a few dive trips to the area, weather permitting.

Koh Similan and Koh Miang are both excellent for hiking. The Similan islands are very rich in flora and fauna for such a small and remote area. The islands are a combination of several forest types, and the convergence of evergreen forest and coral reef. The bio diversity ranges from whale sharks to rare birds such as the Nicobar Pigeon, as well as 27 species of mammals, 22 species of reptiles, and at least 4 species of amphibians.



The main activity here is scuba diving and snorkelling, although fishing trips and sailing vessels also stop here regularly.
As it takes about 3.5 hours to get to the Similans, most dive trips are by liveaboard. Because there are so many dive sites offering so much variety, you should consider a trip of at least four days to fully explore these islands. However, if you are pressed for time there is a hydrofoil from Phuket, which makes the trip in under 2 hours, allowing you to make two dives before returning.
The Similans offer an incredibly varied underwater landscape. Sloping hard coral reefs and shallow coral gardens on the east side of the islands, which are protected from the strong currents. On the west side is totally different scenery. Huge granite boulders, caverns and swim-throughs make for a faster paced and more challenging experience.
