The park headquarters is situated in Tab Lamu, a small fishing village approximately 13 kilometres (8.1 mi) from Bang La On in Khao Lak.
These boats, departing from Tab Lamu, Ko Lanta, Phuket, and Ranong, offer multi-day stays in the Similan National Marine Park.
Specifically, the island of Ko Tachai has been indefinitely closed to tourists since 15 October 2016 to facilitate environmental recovery.
The introduction of these restrictions has elicited responses from tour operators, who express concerns over potential job losses.
Underwater it is full of rock formations and coral reefs in several shapes and forms, resembling such things as deer, leaves, brains, and mushrooms.
These traps have been found to contain a variety of marine life, including trevallies, batfish, barracuda, golden pilot jacks, and triggerfish.
[citation needed] The archipelago has been designated an Important Bird Area (IBA) by BirdLife International because it supports a population of Vulnerable pale-capped pigeons.
