The Similan Islands (Thai: หมู่เกาะสิมิลัน, Thai pronunciation: [mùː kɔ̀ʔ si.mi.lan], Malay: Pulau Sembilan) is an archipelago in the Andaman Sea off the coast of, and part of, Phang Nga Province, in southern Thailand. It is a national park, Mu Ko Similan, which was established in 1982 after a one-year assessment by the forestry department.
As of the park's re-opening on 15 October 2018, the number of visitors allowed to visit the islands will be capped at 3,850 per day in order to slow environmental destruction. Prior to the visitor cap the islands received about 7,000 visitors per day. In 2017, about 912,000 tourists visited. Tour operators have protested the new rules, saying jobs will be lost. All overnight accommodations on the islands have been demolished as part of the rehabilitation program.
Access to the Similan Islands is easiest from Tab Lamu Port, just south of Khao Lak in Phang Nga Province. The park headquarters is in Tab Lamu, which is a small fishing village, just 13 km from Bang La On in Khao Lak. Boats depart daily from the middle of October to the middle of May. The trip takes about three hours each way on slower boats or 70 minutes via speedboat.
During the diving season liveaboard boats head to the Similan Islands. These dive boats depart and return from Tab Lamu, Ko Lanta, Phuket, and Ranong and stay for several days at Similan National Marine Park.
The park is closed in the rainy season, from 16 May-15 October, every year. The island of Ko Tachai will be closed to tourists indefinitely beginning 15 October 2016 to allow it to recover from effects of its heavy tourist burden.
The islands are at
The park is an archipelago consisting of 11 islands, occupying an area of approximately 140 km2 with a land area of about 26 km2. For convenience, the Thai Department of National Parks (DNP) has assigned numbers to the islands. From north to south, they are:
- Island 11: Ko Tachai
- Island 10: Ko Bon, also known as Ko Talu
- Island 9: Ko Ba-ngu, also known as Ko Bayu
- Island 8: Ko Similan
- Island 7: Ko Hin Pousar
- Island 6: Ko Payu, also known as Ko Pa Yu
- Island 5: Ko Ha
- Island 4: Ko Miang, also known as Ko Meang. Park HQ is here.
- Island 3: Ko Payan, also known as Ko Pa Yan
- Island 2: Ko Payang, also known as Ko Pa Yang
- Island 1: Ko Huyong, also known as Ko Hu Yong
Ko Similan: Ko Similan is the largest island. The sea in the area has an average depth of 60 feet. Underwater it is full of rock formations and coral reefs in several shapes and forms, resembling such things as deer, leaves, brains, and mushrooms. Above the water are found many diverse species such as the Nicobar pigeon, mangrove monitor lizards, flying fox and more.
Ko Huyong: Ko Huyong has the longest and widest beach in the park. However, the park prohibits any tourists from landing on the island as the beach is a place where turtles come to lay their eggs.
Islands 1, 2, and 3 are closed to the public due to a turtle hatching protection program and reef conservation efforts. Island number 3 belongs to a Thai princess. Fishing is banned in Similan and Surin National Parks. However, fishing boats are constantly seen in and around the park. When diving, one can often find nets stuck to reefs and illegal fishing traps. In recent years many illegal fishing traps have been found outside the most common dive sites. They have contained among others trevallies, batfish, barracuda, golden pilot jacks, and triggerfish. Fishing traps seem to be overly abundant around Ko Bon and Ko Tachai.
Tourism's environmental impactEdit
The Similan Islands Park is the most overcrowded Thai national park. Five to six thousand persons per day visit the islands during its open season from mid–October to mid–May. The DNP reports that since October 2017 the park has been visited by 883,438 persons. Sheer numbers have resulted in degradation and thus increased regulation.
