Diving at Pulau Biola is done at its very shallow reef, around 10 metres of water. Conditions are usually quite stable but this depends mainly on the weather condition.
The reef at Pulau Biola is quite large, stretching to about 1km before you have to turn. Marine life here is quite good although visibility often hides them. Look out for parrot fish, angle fish, barracuda, rainbow fish, puffer fish and if you are lucky, you may spot eels.
