Koh Chang and the surrounding islands provide some excellent opportunities for both novice and experienced divers. Visibility can reach up to 30 metres during the best months for diving of October to the end of May.
The reef at Hin Luk Bat in particular has a lot of good coral. However, even if you are snorkeling, you still won′t miss out. Around "Bird Island" there are some stunning soft corals with vivid colours and so many small fish that it is like swimming in an aquarium.
Guide to Koh Chang Dive Sites
Koh Lao Ya Nai (Wreck dive)
About 200 m from the mouth of a river on the south eastern headland of Koh Chang, the wreck of the "Thonburi" which was sunk in 1921, now acts as an artificial reef.
Hin Luk Bat
Just over an hour from Khlong Prao beach by boat, Hin Luk Bat has a good diversity of marine life. Divers can see numerous barrel sponges, shelves of soft corals, barracuda and crown of thorns starfish.
Hin Rap
5 kilometres (1 hours) south of Koh Chang, this site has several outcrops and is about 30m from end to end. During the dive you can expect to see many staghorns, barrel sponges, soft corals and lots of small reef fish.
Koh Wai
Immediately east of Koh Klum, this site takes about 1 hours to reach. The reef consists of mainly hard corals with some soft corals along the deeper part. If you are lucky, you may get to see a leopard shark or ray on the sandy bottom.
Koh Gra
About 1 and a half hours by boat, this site is for more experienced divers. The gently sloping hard coral reef has gardens of staghorns from 3 to 5 metres. The are scores of colourful reef fish and often sandy bottom rays.
Koh Rang Pinnacles
This multi level site, about 2 hours away from Koh Chang, is a highlight for divers as the pinnacles create a healthy environment where sharks and rays are more common and small fish abundant. There is a good shelf of coral on the deeper pinnacle at about 15 metres.
Koh Lao Ya Nok (′Bird Island′)
The shallow waters here are an excellent place for snorkeling, with beautiful coloured corals to see and many different types of tropical fish.
