On the northeast side of the island, also known as Pasir Chagar Hutang. The beach is out of bound due to its status as a designated turtle landing point. Snorkelers and divers usually get off from the boats anchored at some distance away from the beach.
This snorkeling spot is fairly deep and one could try to spot the turtles grazing for food at the bottom. Unfortunately I didn't not see any, or did I? According to travel brochures, the three turtle specie that frequent this area are green turtles, hawksbill turtles and Olive Ridleys.
A belligerent titan triggerfish (Balistoides viridescens) stole into the limelight, swimming around and chasing a school of smaller gold-band fusilier (Caesio caerulaurea). I also saw a yellow-margin triggerfish (Pseudobalistes flavimarginatus) here. Other than that, the fish varieties that frequent this area include common damselfish and moon wrasse. You can try fish feeding here too. It is fun to be swarmed by hundreds of fish, especially the "friendly" Indo-Pacific sergeant and scissortail sergeant.
There is also a community of blue cabbage coral which make the underwater scene very colorful, along with table corals and staghorn corals. Otherwise, as I mentioned previously, the depth is quite significant for you to see that much corals a few metres down.
