Koh Chang Diving – Dive Schools, Dive Sites, Wrecks and Prices

Koh Chang diving is a busy and vibrant scuba scene with many different sites, good well-run dive companies, competitive pricing and plenty to see, including the wreck, HTMS Chang.

The diving runs throughout the year, but the best time is from November through to May when the seas are calmest and visibility is usually very good, 10 metres at least but often more. Koh Chang’s lack of strong currents or great depths make it a great place to learn to dive or to refresh your skills.

Dive Sites – Koh Chang Diving

The principal dive sites are the rocky formations of Hin Luk Bat, Hin Rap, Hin Nam Tai (Blueberry Hill), Hin Rua Tek (Banana Rock), Saam Sao Hin, Hin Rap North which all lie 3 to 5 kilometres south and south west of Koh Chang.

Down in Marine Park itself at Koh Rang, the sites and reefs include The Pinnacles (Hin Daeng Ga), Koh Yak and Koh Laun, Koh Thain West and Kuak Hin Ma (3 Finger Reef).


Depths range from 8 to 30 metres with the usual dive time at 1 hour.

Staghorn, Christmas Tree, Table, Gorgonian Fans and Soft coral are found across the sites, with fish, often seen in large shoals, ranging from Moray Eels, Groupers, Trigger, Barracuda, Angel, Clown, Porcupine to Stingrays, with plenty of Nudibranches and Sponges, Sea Turtles and the odd Whale Shark.

Wreck Diving

HTMS Chang, sunk in November 2012 around 5km off the coast of the island, is, at 100 metres, the largest diving wreck in Thailand. It sits upright in 30 metres of water, with the main deck at 20 metres.

It is suitable for all qualified divers, with Open Water able to dive around the tower, the captain’s cabin, above deck and the gun turrets, whilst Advanced can go deeper with some very good swim-throughs.

All the companies offer Nitrox and wreck speciality courses.

Guide Prices – Koh Chang Diving

Prices are consistent across the companies with little aggressive undercutting but companies do offer deals on courses, multiple days of diving, groups and accommodation and prices might go down a little at the end of the main tourist season or during the rainy season.

Prices also vary slightly on location, with dives more expensive down at the Marine Park in Koh Rang, simply because it is further. Pool dives are used for instruction as needed during the courses.
