The most popular diving sites around Pulau Tioman include:
BAHARA ROCK - Bahara Rock is an all-time favourite among the dive sites in Tioman. It features a spectacular underwater garden that includes soft and hard colourful corals with nice formations, huge barrel sponges, sheer rock pinnacles, sea fans and many other attractive underwater species. It is a renowned site for underwater photographers as well. The marine life includes common reef fish such as the emperor angel fish, wrasses, soldier fish, surgeon fish, sweetlips, puffer fish, moray eels, porcupine fish, white eyed moray eels and giant moray eels. Out of season, stronger currents bring larger fish like the barracuda. Around the deeper rocks, black-tip reef sharks are commonly seen, particularly in the mornings, and stingrays are usually seen on the sandy bottom of the reef.
PULAU RENGGIS – This small islet situated just off the west coast of Pulau Tioman, in front of the Berjaya resort, boasts a spectacular coral reef consisting mainly of hard corals, which attract a colourful variety of aquatic life. The depth varies around the site between approximately 10 and 15 meters. It can be easily navigated as you can circle the site, keeping the island reef to one side. If you dive within season, visibility can be excellent and currents are very weak. Notable aquatic life spotted at Pulau Renggis includes hawk’s bill turtles, angel fish, parrot fish, anemone fish, black-tip reef sharks, bat fish, butterfly fish and blue-spotted stingrays.
CORAL ISLAND (PULAU TULAI) - The site's depth varies between 15 and 25 meters and it is well suited to multi-level diving. Visibility at this site is usually excellent, helped by the fact that it is located slightly away from Tioman, and hence further from the majority of the boat traffic. Currents tend to be mild in season. As the name suggests, Coral Island is a great site for seeing the spectacular gorgonian sea fan coral, as well as other colourful soft corals and reef fish. Notable aquatic life spotted at Coral Island includes many sea fans and soft corals, scorpion fish, green wrasse, barracuda, butterfly fish and parrot fish.
PULAU AUR AND PULAU DAYANG– The waters around Pualu Aur offer many exciting dive sites. Underwater pinnacles on the south-east side of the island form one of the most challenging dive sites. The pinnacles rise 30 m from the seabed to just about 10m from the water surface. The other oft-dived site is none other than the well-known Rayner’s Rock, lying east of Pualau Dayang. Whale sharks and manta rays are a common sight around Rayner's Rock. The channel between Pulau Aur and Pulau Dayang also offers a few dive sites that are rich in coral reefs in relatively shallow waters, making them suitable dive sites for night diving and also for snorkelling during the daytime.
