What are the Similan Islands?
The Similan Islands are a magnificent collection of islands located in the Andaman Sea. These gorgeous islands possess such natural beauty that even amateur photographers can capture breathtaking photos.
Renowned as one of the world’s premier diving destinations, the Similan Islands boast abundant marine life, including vibrant coral reefs, crystal-clear waters, and pristine white beaches. Notably, the islands are characterized by their distinctive rock formations comprising colossal boulders, shallow coastal areas, and lush tropical forests.
Due to its popularity, excessive tourism has adversely affected the islands. The issue of overcrowding became so significant in 2018 that park authorities implemented strict visitor limitations.
Initially set at 3,850 people per day, this number was reduced to 3,325. Before these restrictions, the islands received up to 7,000 visitors daily.
The term “Similan” originates from the Yawi language, a Malayan dialect, and translates to “nine.” Initially, the park consisted of nine islands numbered 1 to 9. However, in 1998, the park expanded to incorporate two additional islands situated farther away: Kho Tachai and Kho Bon.
While each island possesses a specific name, it can also be identified by its numerical tag. The islands are Kho Hu Yong (#1), Kho Payang (#2), Kho Payan (#3), Kho Miang (#4), Kho Ha (#5), Kho Payu (#6), Kho Hin Pousar (#7), Kho Similan (#8), Kho Bangu (#9), Kho Bon (#10, also known as Kho Talu), and Kho Tachai (#11).
Where are the Similan Islands?
The Similan Islands, designated as a national park in 1982, form an enchanting archipelago consisting of 11 islands in the Andaman Sea, approximately 70 km from Phang Nga Province’s coast. Encompassing a total area of 140 km², with 26 km² being land, this pristine park offers breathtaking natural beauty.
Khao Lak and Phuket are the nearest popular towns on the mainland, while the closest pier, Thap Lamu Pier, is located south of Khao Lak.
Why you should go to the Similan Islands
Similans Islands offer a different scenic experience than the dramatic limestone islands of Krabi or Phang Nga Bay, commonly associated with the Andaman Sea. Instead, you will encounter low-lying formations covered in dense forests.
Ironwood and gum trees are among the larger trees, while the denser undergrowth consists of jackfruit, rattan, and bamboo. These islands are inhabited by crab-eating monkeys, dusky langurs, squirrels, bats, lizards, and a diverse range of bird species (although the monkeys are elusive and seldom seen by casual observers).
At first glance, the most remarkable feature of these islands is the presence of enormous boulders that scatter the western and southern shores of several islands. Another fascinating aspect is the picturesque white coral-sand beaches, often deserted and magnificent.
However, the most captivating sights lie beneath the waves. You can discover some of the world’s most spectacular coral growth here. The same boulders that dot the shores have transformed the waters surrounding Similan Islands into an exhilarating playground for divers. Here are the reasons why the islands should be among the places to visit in Thailand:
Snorkeling and diving paradise
Similan Islands offer ideal conditions for an extraordinary diving experience. These islands provide a perfect setting for underwater exploration with warm, crystal-clear waters, mild to moderate currents, and visibility ranging from 20 to 30 meters.
From late October to May, divers can discover the rich marine life thriving beneath the surface and marvel at the breathtaking seascapes throughout the diving season. Whether you prefer gently sloping coral reefs, deep rocky gorges, or more challenging depths with varying currents, the waters surrounding the Similan Islands cater to the preferences of every diver.
Prepare to be amazed by the extraordinary submarine rock formations, colossal granite boulders, captivating swim-throughs, and magnificent giant fan corals found here. Although scuba diving is highly popular, snorkeling is also a fun activity that can be enjoyed across the islands.
You can rent snorkeling equipment from the Similan Islands Marine National Park Headquarters. Alternatively, if you’re planning day trips from Phuket or Khao Lak, bringing your gear is convenient to avoid renting upon arrival.
Stunning outdoors
While the islands may not be vast in size, they offer an opportunity to venture beyond the waters and immerse yourself in the lush forests, uncovering secret havens few have dared to explore. Whether you prefer to follow established hiking trails or embark on off-road adventures, there is ample time to discover breathtaking vistas along the journey leisurely.
However, it is advisable to pack insect repellent and a water bottle as essential companions before embarking on your expedition.
Lovely and secluded beaches
The idyllic setting of the Similan Islands boasts pristine white sandy beaches, offering the perfect environment for relaxation and unwinding. While activities such as snorkeling, diving, and swimming are the main selling points, in a way, they are just as endearing as basking in the gentle embrace of the sun’s rays while the soothing sound of waves caresses the shoreline.
As the Similan Islands have gained popularity among divers, this charming archipelago has become a favored destination for yachts and tour boats. Given its growing fame, it’s natural to expect some boat traffic and visitors during the day. Khao Lak, the closest well-liked tourist town, offers visitors a wide array of resorts.
In the past, there used to be a campsite on the islands; however, camping is no longer permitted to help control visitor numbers. Additionally, there is no accommodation available within the islands’ national park. For those seeking dining options on the islands, a solitary restaurant is in Kho Miang. It operates daily from 8 am to 2 pm.
Impressive wildlife diversity
The Similan Islands offer a captivating haven for animal lovers, showcasing a remarkable array of wildlife. Whether you are an avid birdwatcher or appreciate observing animals thriving in their natural environment, visiting this destination promises a worthwhile experience.
The Similan Islands boast an impressive collection of Southeast Asia’s marine species, including manta rays, whale sharks, whitetip reef sharks, blacktip reef sharks, leopard sharks, bluespotted ribbontail rays, spotted eagle rays, bowmouth guitarfish, shovelnose guitarfish, hawksbill sea turtles, olive ridley sea turtles, leatherback sea turtles, green sea turtles, giant morays, fimbriated morays, greyface moray eels, great barracudas, green humphead parrotfish, ribbon eels, giant trevallies, humphead wrasses, and many more.
While sightings of whale sharks and manta rays are rare, they occasionally grace these waters, particularly from March to April. Over the years, the islands have become home to less than 120 bird species.
Among the rarer avian residents in Thailand, you can find parasitic jaegers, roseate terns, and Nicobar pigeons within the Similan Islands. In addition, birds such as barn swallows, greater coucals, common mynas, Pacific reef egrets, little egrets, pied imperial pigeons, and white-bellied sea eagles thrive in this ecosystem, among others.
When is the best time to visit the Similan Islands?
The ideal period to visit the Similan Islands is from December to April.
Late February to mid-March is recommended for the most pleasant experience with minimal rainfall and calm ocean conditions. Although temperatures begin to rise during this period, the sea remains tranquil, and the evenings are pleasantly warm.
Mid-March to May, the summer months, provide excellent opportunities for snorkeling and diving.
However, it is crucial to avoid planning day trips to the island in September, as the monsoon season brings unfavorable weather conditions. If any agency promises such trips during this time, exercise caution. Once the monsoon season ends, the island becomes accessible to tourists. Therefore, it is essential to confirm its timings before booking your holiday.
It’s important to note that the park is closed from May 16th to October 14th due to adverse weather conditions, making it highly unfavorable to travel there during this time.
How to get to the Similan Islands
The closest departure point to the Similan Islands is Thap Lamu Pier, situated in the Thai Muang district of Phang Nga province. Boat journeys from there typically take about 3 hours. It’s important to note that foreign visitors must pay an entry fee of about 500 baht (~ 14 USD).
There are various types of boats available for visiting the islands. Liveaboard dive boats are highly recommended for longer stays, while day-trip dive boats and snorkeling speed boats are suitable for day trips. The primary pier for accessing the islands, known as Khao Lak Pier, is Thap Lamu Pier. It is located 65 km away from the main islands, 55 km from Kho Bon, and 72 km from Kho Tachai.
In addition to Thap Lamu Pier, there are several other nearby piers that different tour operators utilize to transport their customers from hotels.
Another option is Baan Nam Khem Pier, approximately 22 km north of Khao Lak. This pier is mainly used for reaching Kho Bon and Kho Tachai islands. It is roughly 52 km from Kho Bon, 55 km from Kho Tachai, and 72 km from the original nine islands.
The Mu Kho Similan National Park Office and the main visitor center are located on the mainland near Thap Lamu Pier. Additionally, visitor centers are on Kho Similan and Kho Miang Islands.

For a more secluded island experience, consider visiting Koh Kood. With its pristine beaches, dense jungle, and laid-back atmosphere, Koh Kood is the perfect destination for those seeking tranquility and natural beauty.
To reach Koh Kood from Bangkok, take a minivan to Laem Sook Pier in Trat Province. Minivan tickets cost around 300 THB (USD 8) per person each way, departing early from Ekamai Bus Station in Bangkok. And then, from Laem Sook Pier, a two-hour boat transfer to Koh Kood is required, with departures at 10am, 1pm, 2pm, and 3pm. A ticket costs about 600 THB (USD 17) per person one way. Also,Koh Kood is closer to Bangkok than southern Thai islands.
– Pai:
Escape the hustle and bustle of city life and head to Pai, a charming town nestled in the mountains of northern Thailand. Explore waterfalls, hot springs, and lush rice fields, and don’t miss the opportunity to rent a scooter and explore the scenic countryside.
Pai is situated in the Mae Hong Son Province, within the Pai District. Positioned about 135 kilometers northwest of Chiang Mai, one of Thailand’s prominent cities.
To go there, it takes about3-hour bus ride from Chiang Mai to Pai for just 200 Baht per person (USD 6). Starting from Chiang Mai is the simplest and most common route. If you’re arriving from elsewhere, inquire at your accommodation, a tourist center, or a bus station for guidance.
