[3] Administratively, the islands are part of Tambon Ko Phra Thong, Khura Buri district, in Phang Nga province, Thailand.

Christie Island, which marks Myanmar's southernmost point, is situated 18 km (11 mi) north of Ko Surin Nuea.

[3] Geological theories suggest that a subduction event during the Mesozoic era, involving the Burma and Sunda Plates, led to the formation of the numerous granite islands and undersea pinnacles along the west coast of Thailand.

As a result, various geological structures, including pinnacles and outcroppings, were dislodged and amalgamated onto the ascending plate, eventually giving rise to small island chains and underwater seamounts.

[5] The Surin Islands are home to a small community of the Moken or Morgan people (Thai: ชาวเล, romanized: chaao laeh, lit.

[2] According to these oral traditions, when the villagers observed the sea receding unusually from the beaches, they recognized it as a precursor to a tsunami, a phenomenon encoded in their lore through the legend of the laboon or giant wave.

This legend passed down through generations, teaches that a tsunami typically arrives as a series of waves and that an abnormally rapid retreat of the sea, followed by an incoming white breaker, is indicative of an imminent laboon, even in the absence of other warning signs like wind changes or shifts in the sky.

Historically, they engaged in a subsistence lifestyle as hunter-gatherers, relying on the trade of shells, sea cucumbers, and fish in exchange for rice and other essentials.

[8] Mu Ko Surin National Park (Thai: อุทยานแห่งชาติหมู่เกาะสุรินทร์, romanized: oot yaan haeng chaa dti muu gaw soo ri noht), officially designated as Thailand's 30th national park of Thailand on 9 July 1981[1] and later expanded on 6 July 2007, encompasses a group of islands along with their surrounding waters.

Accommodation options on Ko Surin Nuea include camping at Mai Ngam beach and a limited number of lodgings at Chong Kaad Bay.

Mu Ko Surin National Park is typically open from 15 October to 15 May annually, although it may close earlier depending on weather conditions.

[2] Mu Ko Surin National Park features a diverse range of ecosystems, with primary rainforests forming the majority of its terrestrial landscape.

[2] Richelieu Rock is a solitary limestone pinnacle standing from around 30 to 35 m (98 to 115 ft) depth with its peak right below the sea surface at low tide and home to some of the largest marine life species in Thailand.
