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

Koh Chang diving and wreck divingKoh Chang diving is a busy and vibrant scuba scene with many different sites, good well-run companies and plenty to see, including the wreck, HTMS Chang, recently sunk, sitting pretty and accepting both fish and divers.

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.

Koh Chang Diving – 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.

Koh Chang Diving – Prices

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.

Please note that there is a 200bt (100bt kids) government tax or 40bt/20bt (Thai Nationals) for visiting Koh Rang. Collection is either in Bang Bao before you leave or on site by the rangers in an inflatable dinghy. This fee is not included in our guide to the diving prices.
