Koh Payang and Koh Payan are two similar island in the southern part of the Similan Park, the second belongs to a Thai princess. Both islands are characterized by rocky hills covered with lush tropical vegetation and beautiful granite formations around the coastlines.

Nevertheless, a little awaythere are some interesting dive sites to which access is allowed. Between these Shark Fin Reef and Boulder City are the most frequented by the dive boats. Boulder City is located about 2 Km off the east coast of Koh Payan, and it is the southernmost diving site in the Similan Islands. As its name suggests, Boulder City is a huge submerged granite formation characterized by three main pinnacles surrounded with hundreds other smaller boulders scattered around a flat sandy bottom. Shark Fin Reef is located about 2 Km north of Boulder City, and it’s basically part of the same submerged rocky ridge. Shark Fin Reef is the largest of all the Similan Islands dive sites, over one kilometre from its northwest tip to southeast ends.

Koh Ha

Koh Ha small rocky island located roughly in the centre of the Park, just a few hundred meters to the east of the big sister Koh Miang. It has no beaches but it's still one of the most visited by day trip boats to do snorkelling. Its reef also offers great opportunities for divers, with some of most beautiful dive spots in the Similan Islands. Its Anita’s Reef is one of top five dive sites of Park. It is situated on the east coast of Koh Ha, and consists of a gentle sandy sloped reef interspersed with patches of staghorn coral, table corals and large coral bommies covered with soft corals, sponges and colourful gorgonian sea fans. The main attraction here is a huge coral bommie in the south-east of the site. It rises from the sandy bottom at more than 20 meters deep to just 12 metres below sea surface. Hide Away Bay is another interesting dive site close to Koh Ha. Also known by divers as Barracuda Point, it is located a bit further south-west of Anita’s Reef. The site combines the two different topographies of diving in the Similan Islands, with the southern part characterized by large granite boulders and the northern section made of fringing coral reef. The coral reef in the northern area starts from 7 metres below sea, with an average depth of 12 metres and a maximum depth of 25 m. It consists mainly of hard and soft corals, interspersed with colonies of staghorn, gorgonian sea fans and coral bommies of various sizes. The southern section of Hide Away Bay is deeper. Here the large boulders descend down to more than 35 meters on a sandy bottom. Besides the usual reef fishes, the marine life in Koh Ha’s dive sites includes other larger specimens like Wrasse Napoleon and Black Tip Sharks. In the surrounding waters swim large schools of pelagic fish, such as various families of Snappers, Soldierfish and Fusiliers. On the sandy bottom you will find rare Blue Spotted Stingray and Spotted Garden Eel.Read More

Koh Payu

Koh Payu is a middle sized island between Koh Miang and Koh Similan. The lush island has a narrow white sandy beach on its north eastern side which is surrounded by a beautiful shallow reef, one of the nicest spots for snorkelling into Park. In the southeast coast there is also East of Eden, which is no doubt one of the best dive spots of Similan Islands and probably one of most famous in Thailand. Feature of this site is a colourful reef that starts 5 metres below sea level that, after a slow initial slope, steeply reaches the depths of 35 metres with an average diving depth of 20 metres. The site is home to the biggest coral head called "The Orchid Garden", which starts at 25 metres and rises up to 12 metres covered with violet and blue corals, staghorn coral, pore corals, orange and red gorgonian sea fans, colourful anemones and bommies. This reef is really stunning for underwater macro photography. Here you will find a huge density of all the reef fishes that the Andaman Sea can offer including Hawksbill Turtles, Ribbon Eels, Frogfish, Blue-ring Angelfish, Clown Triggerfish, Pipefish, giant Moray Eels, Butterflyfish, Royal Angelfish, Lionfish, Jackfish and Sea Snakes. In the surrounding waters are large schools of pelagic fish, such as Amberjack, Dorado, Barracuda and Trevally. The deeper end of the reef is a sandy seabed, home to Groupers, Stingray, Black Tip and Leopard Sharks. Located just off the north coast of Koh Payu there is Deep Six, which is one of the most exciting dive sites in the Park. The site consists of giant granite boulders to form a V-shaped ridge, which starts just 5 metres below the sea surface and then descend dramatically to more than 40 metres deep. Either sides of ridge are rich of canyons, tunnels, swim-throughs and caves, among them the main is a large cavern at the anchoring point of the buoy line. Clusters of other smaller boulders are scattered all around. Along the reef the marine life is prolific with a huge variety of fish and invertebrates, such as Octopus, small Lobsters, Blue Sea Stars, Sea Cucumbers, Shrimps and Crabs. Closer to the reef or hidden among crannies, corals and anemones you'll see Nudibranches, Parrotfish, Emperor Angelfish, Frogfish, Clownfish, Pipefish or predators as Lionfish, Scorpionfish, Moray Eels and occasionally Turtles.

Koh Ba-Ngu

Koh Ba-Ngu is the northernmost of the original nine islands of the Park. The tiny island has a curious irregular shape, which for someone resembles a skull. The shoreline is dotted with piles of granite rocks of different shapes and sizes. Koh Ba-Ngu is surrounded by one of the most exciting coral reefs of Park, according to the divers, with several dive spots. Among these the most famous are Christmas Point and North Point. Christmas Point is located just off a small bay in the western tip of island. The dive spot consists of a cluster of submerged boulders and pinnacles on a relatively flat sandy seabed. With a diving depth between 10 and 40 metres, it offers an exciting drop-off with tunnels, hollows, caverns and huge collapsed stones where can swim through. The rock formations are covered with colourful soft corals and gorgonian sea fans. Christmas Point derives its name from the numerous vivid red, yellow and green corals that cover the walls of its caverns like a 'Christmas Tree'. North Point is one of the most challenging dive sites in the Similan Park. Also known as Triple Arches or Golden Arches, it is just 50 metres off north shore of Koh Ba-Ngu. North Point is the other most popular dive spot and it also one of the most challenging in all Similan Park.

Similan Islands

The Similan Park is located 65 km off the coast of Khao Lak, Phang Nga Province. The nearest access to the Similan Islands is Thap Lamu, a small fishing village located just 15 km from Khao Lak, 90 Km north of Phuket and 120 from Krabi. From its piers depart all boats to Mu Koh Similan Marine Natural Park. Journey time from Thap Lamu Pier is around 70 minutes. The round trip is performed by large offshore speedboats with engine powers which are close to 750 hp. The Park is easily accessible from all seaside resorts in southern Thailand with daily excursions and even multi-day cruises for diving enthusiasts. The streets of Khao Lak, Phuket or Krabi are full of tourist agencies and kiosks selling the packages offered by many authorized tour operators. Beware and compare rates before choosing between them, considering not only the cheaper price but also the quality of the proposed service. The majority of these tours provide the transfer by minivan from your hotel with departure at about 06.30; the roundtrip by speedboat from Thap Lamu Pier; the visit of Koh Ha and Koh Payu to enjoy snorkelling and swimming; a long stop for lunch buffet and relax on Koh Miang; the visit of Koh Ba-Ngu, the northernmost island of Park, to snorkelling, and in finally another long stop on Koh Similan, the main island, to enjoy the beach and climb to the viewpoint on the Sailing Rock. The departure time from the Similan Islands is at 15.00; the arrival time at the hotel is between 19.30 and 20.00.
