The Gulf of Thailand has a lot of hidden beauties and in Koh Chang you can discover some of them.
Amateurs or professionals, both can find their part of fun.
There are few places around Koh Chang where you can snorkel by yourself but you will spend time to access them and the result will be far from your expectation. That's why this activity is linked to the boat trips.
There are lots of diving shops and schools along the island and all travelling agencies can arrange you a diving or snorkelling tour. Most of the big diving companies have their office and boats located in Ao Bang Bao, at the south of the island. Some of them can even pick you up directly from your resort.
If you have never dived before it can be a good opportunity to get few lessons. Check with the different diving companies, they will provide you all the information you need.
For the experimented divers, there are lots of reefs with amazing corals as well as a 100 meters long wreck sunk in 2012. If you are lucky you can see whale sharks, dolphins, turtles and various exotic and colourful fishes.
If diving is not made for you, you can still snorkel. I strongly recommend Thaifun. It's the most known company in the island. They will pick you up directly on the closest beach where you are located.
Thaifun will bring you to several small islands where you will be able to swim and snorkel. You can rent the snorkelling equipment inside their boat.
The crew will entertain you during the full trip which starts early in the morning to end at the sunset.
If you have children, they will have a lot of fun.
