Bias Tugel is a dive site off a Bias Tugel beach that is made up of a coral plateau that is relatively large. It has a gradual slope to about 8 meters and then slopes further to around 30 meters where there is a large ledge. The area is also known as White Sand Beach because of the amazing white beach.

There are many bommies (Coral mounts), boulders, table corals and fan corals at the site making up just some of the hard and soft coral. The coral bommies in particular are some of the best in Bali and are known as being in pristine condition. Some of them are the oldest bommies that can be found in Bali.

The water temperature is normally above 28 degrees and can reach 30 degrees but it can dip down to 20 degrees in some of the deeper parts of the dive.

The dive itself is very calm with some swell and only the occasional current. Visibility is good and can reach 30 meters. The reef has some great macro marine life such as nudibranchs, pygmy seahorses being protected amongst the gorgonian fans, and gobies. It is common to see small cuttlefish and larger ones can occasionally be seen. As there are a few bommies and boulders on the seabed, Squirrelfish have often been seen hiding amongst these natural nests.

There is a huge variety of moral eels as well found amongst the boulders and hard coral, including both blue ribbon and black ribbon eels. There are triggerfish, sweetlips, wrasse, butterfly fish, frogfish, lionfish and scorpion fish. There are large schools of red-toothed triggerfish and it is becoming a site well known for spotting sharks and turtles.
