This is the top most activity around this island. You will get to see many marine life because the visibilty is good.
The waters around Pulau Aur are deeper and clearer than around the inner islands and because of the great distance from the mainland, sightings of pelagic are possible. Whale sharks and manta rays were sighted before.
Pulau Aur provides a clean sea with high visibility and lots of different aquatic life. During my dives, I have come across white tip shark, sea turtle, lion fish, cuttle fish and many more. A weekend trip would give you an idea, but for sure you would want to stay more.
Well, to be honest, there aren't any other activities that you can find here... but it's sure a suitable place to do your open waters.
The water current is almost negligible and there are actually sandy patches below where you are able to kneel.
If you do not have a license to dive, you can either attempt to take up the Open Water Dive Course there which many Singaporeans did or you can snorkel at designated area.
