The Similan Islands, located about 50 Kilometers west of Khao Lak, Thailand and are composed of nine granite islands washed by a clear blue tropical ocean and blessed with some of the world’s finest beaches.
“Similan” is a Yawi or Malay word, which means nine or a group of nine islands. In 1982, this 128 square kilometres area was declared a marine national park, and in recent years this group of nine small islands has become one of the leading attractions for visitors to Southern Thailand. Listed as among the very best beaches in Thailand. While we are certain o have some bias – why not read about Thailand’s Islands & Beaches (Regional Guide)
Similan Park Fees
The Similan Park entrance fee is 500 THB for foreigners (and for children 300 THB). However the park fee is only 100 THB for local tourists (children 50 THB). throughout the 2015-2016 season it is an additional 200 THB for each day that you are there.
The Similan Park Fee usually stays the same throughout the year, but don’t be surprised if there are changes!
With the establishment of stations by the Royal Forestry Department on Koh Miang and Koh Similan, fishing within the national park boundaries was banned and the unwanted visitors were substituted by tourists, especially after 1987, when leisure boats and dive operators started coming out on a regular basis.
Today Mu Koh Similan National Marine Park and all its reefs have recovered from earlier disturbances. Boats entering the Similan Islands National Park have to follow strict rules imposed and controlled by the national park officials, have to use the moorings prepared by the national park and use closed waste water systems to avoid any pollution.
Activities include Diving, Snorkelling, birding, camping and lazing on the beaches. Many tour operators make visits to these islands. Please see our links page for more information on agents we recommend.
Similan Island Information: Names
The nine Islands are named from South to North.
The Southernmost island – Ko Huyong is also known as Similan Island #1 Ko Payang also known as Similan Island #2 Ko Payan also known as Similan Island #3 Ko Miang also known as Similan Island #4 Ko Ha also known as Similan Island #5 Ko Payu also known as Similan Island #6 Ko Hin Pousar also known as Similan Island #7 Ko Similan also known as Similan Island #8 Ko Bangu also known as Similan Island #9 is the Northernmost of the islands.
Part of the park, but geologically and physically quite separate are Koh Bon and Koh Tachai.
Ko Bon (Bon Island) – with no beach and no accommodation this is still an island to visit. A portion of the islands coral was destroyed by dynamite fishing before it became part of the National Park. It still holds some stunning scenery. This is also the most common site for sightings of Manta Rays.
Ko Tachai (Tachai Island) Tachai Island is located at the northern most tip of the park. There is a beautiful white powdered beach on the island. There are several sites suitable for SCUBA diving. In addition there are several reefs suitable for snorkeling. Whale sharks and Manta rays are often found here during their seasons. Facilities incloud a freshwater source, campsites, a restaurant and small boats for snorkeling. ”Similan” comes from the Sea Gypsies. They speak a language similar to Malay. They named them “The Nine Islands” (Sembilan is “nine” in Malay). They designate the islands by names in Thai-and a number. The islands achieved national park status in 1981 and thus are fully protected under Thai law.
The National Park Authority maintains a residential center for Park Rangers and support staff on two of the islands: Ko Similan (Island #8) which is the largest Island and Ko Miang (Island #4), which lies mid-way through the chain. These are the only residents allowed on the islands, excepting the overnight guests.
Recently, the islands have come to the special attention of the Thai Royal Family which further assures protection of this national treasure. The Princess has had a “cabin” built on Island #4 and visits almost every year. The Similan Islands are famous for hosting some of the most beautiful beaches, snorkeling and dive sites in Thailand and are one of the better areas for diving in the entire world. One of the most fantastic characteristics of the islands is that we have two entirely different types of environments in one destination.
The rocky slopes of the Western slopes are barren and feature massive boulders and wind swept trees. The Eastern Side features the famous white sand beaches and coral reefs
