About Surin Islands

Open the interactive map of Surin Islands

Popular for its coral gardens and white beaches, Surin Islands are one of the most famous diving and marine life viewing sites in the world, no doubt the best in Thailand. The islands are within Mu Ko Surin National Park.

Surin Islands are an archipelago of five islands within Mu Ko Surin National Park, in Phang Nga Province. The islands are 55 km off the coast, 100 km north from Similan Islands in the Andaman Sea and just 18 km from the oceanic border of Burma. The national park is covering an area of 135 km² of which 76% is sea.

The main islands are Ko Surin Nuea and Ko Surin Tai which are only 200 meters apart, the corridor between both islands is shallow and a popular place for snorkelling. The other three small islands are Ko Ri, Ko Khai and Ko Klang.

The islands are one of the very few untouched places in Thailand. Other than a small Moken village and park premises, there are no other buildings on the islands.

Activities

Diving and snorkelling are the main activities in the islands. The best time for diving is around December to April when the wind is minimal and the average water temperature is around 29 °C. Although sighting is rare, February to April is the more ideal time to spot large pelagic species like manta rays and whale sharks.

Snorkels and lifejackets are available for rent from the visitor center of the park, each item for 40 Baht per day.

It is possible to camp at one of the two campsites or rent one of the few bungalows in the islands, right next to the white beaches.

The islands are perhaps not a popular birding destination, but there are few migratory birds visiting the islands, not found elsewhere in the country. Wildlife watching possibilities on land side of the islands is limited.

Fact corrections

When searching about Surin Islands, hundreds of commercial websites will list a number of “facts”, often copied over from other websites, some not true, others intentionally misleading for business reasons or not verified for a while. Below we will list few;

The islands are not “in a quiet corner of Thailand” as claimed, the national park is visited by a significant number of tourists every day during the open months. During the peak times of year around 450-800 people visit the park every day.

The park is closed during the rainy seasons, the annual closure periods may vary from year to year. Sometimes the park may close earlier than the announced time because of bad weather. See further below for the closure dates, we will try to update the dates as much as we can.

Koh Ban and Koh Tachai Islands are not part of the Surin Islands, they are part of Similan Islands 40 km further south.

The discovery of the islands as diving sites by Jacques-Yves Cousteau and naming of Richelieu Rock by him is disputed. Cousteau never got north of Koh Bon island which is south from Surin Islands.

Wildlife

The marine diversity of the islands are one of the best in the world. According to a series of studies from 2001 to 2002 (by Saisaeng, 2002; Sittithaweepat, 2001; Worachananant, 2000) more than 260 species of reef fish, 68 species of coral, 48 species of nudibranchs and 31 species of shrimp was recorded in the national park.

The shallow and deep waters around the islands gives the opportunity to see some of the most impressive marine species in the continent, some rare others common; Manta rays, whale sharks, great barracuda, blacktip reef sharks, whitetip reef sharks, leopard sharks, olive ridley sea turtle, hawksbill sea turtle, leatherback sea turtle, green sea turtle, bluespotted ribbontail rays, Kuhl's maskrays, giant morays, boxfishes, trevallies, puffers, butterflyfishes and many more.

Rare sighting, but whale sharks do visit Surin Islands from time to time

There are currently 107 known bird species reported from Surin Islands. In Thailand, Swinhoe's storm petrel and Streaked shearwater are two critically endangered non-breeding visitors that has only been recorded in Surin Islands. Other rare birds are parasitic jaeger, beach thick-knee and great-billed heron.

Very little is known about the snake species found in the Island but king cobras, reticulated pythons and mangrove pit vipers are confirmed species. Surin bent-toed gecko is an endemic species of gecko only found in Surin Islands. Two of the more common monitor species of Thailand, clouded monitor and water monitor are both found in the islands.

Possibly partly caused by global warming, 90% of the coral life in Surin and Similan islands died out followed by temperature changes back in 1998 and 2010. The 2010 event called Reverse Indian Ocean Dipole caused a natural "coral bleaching" killed almost most of the marine life. In August 2019, the park authorities announced that the corals nearly fully recovered.

Visiting

Khura Buri is the nearest small town not too far from the coast. The popular tourist towns in the area are Phuket, Khao Lak, Krabi, Ao Nang and Koh Samui with Khao Lak being the nearest.

Visiting the island can be done either with day trips with speedboats or by multiple day cruises.

It is possible to make a day trip from Phuket, Krabi or Ao Nang, but the pier will be in 3.5-4 hours driving distance, not recommended. For a daytrip, it is better to get to a nearby town, either Khao Lak or Khura Buri.

To get a better understanding of the distances and location of places around Surin and Similan Islands please open the interactive map from this page. The map will outline all important spots like the piers, islands, beaches, diving spots etc. Some information can be read directly from the map.

The smoothest way to get to the islands is by booking a scuba diving liveaboard tour or a snorkelling tour via various operators. These tours normally include pickup from hotel, ferry arrangements, diving equipment, meals and return to the hotel.

The visitors intending not to book any tour and get there by public transportation are recommended to stay in Khura Buri Town overnight. The reason for this is because the ideal time to take a ferry to the islands is in the early morning.

Ferries tend to anchor at several classic spots along the islands, of which one is Chong Kat Bay in Surin Nuea Island.

Khura Buri Pier & Surin Islands Visitor Center

The nearest embarkment point to Surin Islands is Khura Buri Pier, about 12 west of Khura Buri Town in Phang-Nga Province and 2 km west from Phet Kasem Road. This is also where the park visitor center is.

It is relatively easy to get to the islands by public transportation options from the major towns in the area. Minivans leaves from Phuket, Krabi and Khao Lak regularly, they drop off customers at the pier. Once at the pier, it is easy to purchase tickets and hop on to a ferry.

The staffs at the hotels in Khao Lak, Krabi, Phuket and other towns normally helps calling minivan operators which comes and picks hotel guests from the hotels, quite hassle-free. If hotel staff can’t help, they normally can give advice about the nearest agency to make arrangements from or give the directions to the minivan stations.

Coach buses from Bangkok to Phuket and from Chumphon to Phuket do stop at Khura Buri.

Getting to the nearest towns

There are three airports in the area, all in nearly the same distance to Khura Buri Pier.

Moken Village

Show on map

There is one small communities of the ethnic Moken minority, locally known as "Chao Lay". Mokens are nomadic sea people who live in the Burmese Mergui Archipelago. The total Moken population of the Islands is around 329 people (by 2019) in 78 houses.

Moken community has been hit by two disasters over the last two decades;

The first disaster wiped out back then two villages during the December 2004 Tsunami. When the villagers saw the sea water draw back from the coast, they knew a tsunami was on the way. The entire population in both villages managed to escape to the higher grounds to safety but their houses, all their other belongings were completely wiped out. Only half of the boats survived the catastrophe. The community from both of the villages reconstructed a single village called Ao Bon Yai in Surin Tai Island.

After the tsunami the houses that previously were built on water forced to be built further in land by park authorities. This resulted in houses being built very near each other. The second disaster happened in February 2019; while a villager try repairing a boat under a house, the gas-filled engine of the boat took fire and rapidly spread out to all 65 houses which were built tightly together.

When visiting the village please follow the common sense; respect the community by having shirt on, do not use your camera without permission. Just imagine how you would think if you got tourists around your home every day.
