This island off Mersing, along with Pulau Dayang, Pulau Lang and Pulau Pinang, are rated among the best diving destinations within the Johor Marine Park area. The deeper waters around the area ensure good visibility and a large variety of marine life. The island is especially popular among weekend divers.
The rich pelagic action also attracts numerous sport fishermen, trying their luck with the marlins or sailfish swimming outside the marine park island. Many private yachts anchor in the calm waters between Pulau Aur and Pulau Dayang.
The main reef is located towards the southern end of Pulau Aur and Pulau Pinang. The top of the reef begins at about 12m and slopes in excess of 25m, making it ideal for diving.
