12HTMS Kut Wreck

Hin Daeng
Koh Lanta · Krabi Province · Thailand
A submerged red-coral pinnacle rising from the depths of the Andaman Sea south of Koh Lanta, famous for manta ray cleaning stations, whale shark sightings, and walls carpeted in crimson soft coral that give the site its name.
Koh Bon West Ridge
Khao Lak · Phang Nga · Thailand
A current-battered granite ridge on the western face of Koh Bon where manta rays visit cleaning stations year-round and the exposed position attracts pelagic visitors from the Andaman Sea's deep water.
Torinla Bay
Khao Lak · Phang Nga · Thailand
A pristine coral bay in the Surin Islands marine park where Moken sea gypsy knowledge guides divers to hidden reef gardens, sea turtle nesting grounds, and some of Thailand's healthiest shallow coral formations.
Koh Phayam
Ranong · Ranong Province · Thailand
A little-known island in the northern Andaman Sea off Ranong province, where undived coral reefs, rocky pinnacles, and mangrove channels support sea turtles, leopard sharks, and prolific macro life in water that sees virtually no dive tourism.
Yong Hua Shipwreck
Koh Lipe · Satun · Thailand
A Chinese cargo vessel resting upright on the seabed south of Koh Lipe, now colonised by soft corals and swarming with resident fish schools, offering the Andaman Sea's most accessible wreck dive with easy penetration for certified divers.

A protected archipelago of 42 limestone islands west of Koh Samui where sheltered reefs between dramatic karst formations harbour healthy coral gardens, reef sharks, and sea turtles in the Gulf of Thailand's most scenic marine park.
Tanote Bay
Koh Tao · Surat Thani · Thailand
A boulder-strewn bay on Koh Tao's eastern coast where granite formations create swim-throughs and caves, hawksbill turtles rest in crevices, and artificial reef projects have revitalised the marine environment.
Haad Yao Reef
Koh Phangan · Surat Thani Province · Thailand
A gently sloping fringing reef off Koh Phangan's western coast where shallow coral gardens, resident blacktip reef sharks, and dense schools of fusiliers make it an ideal site for new divers and underwater photographers seeking relaxed, marine-rich conditions.
Sail Rock
Koh Phangan · Surat Thani Province · Thailand
A massive granite pinnacle jutting above the Gulf of Thailand between Koh Phangan and Koh Tao, renowned as the region's premier site for whale shark encounters and featuring a dramatic vertical chimney swim-through teeming with glassfish.
Emerald Cave (Tham Morakot)
Trang · Trang · Thailand
A 80-metre sea cave on Koh Mook that opens into a hidden lagoon of emerald water surrounded by sheer limestone walls, offering a unique swim-through dive combining total darkness with a spectacular cavern emergence into tropical light.
Koh Mak
Trat · Trat Province · Thailand
A small, car-free island in Thailand's eastern Gulf where shallow coral gardens, bamboo shark encounters, and seahorse-rich seagrass beds offer gentle diving in warm, calm waters far removed from the crowds of nearby Koh Chang.
