Tanjung Basi is located at the northern tip of Pulau Perhentian Besar. Just like Tanjung Butung, this site is an extension of a rocky headland that stretches out into the sea at a maximum depth of 22 meters. Large granite boulders make up most of the seaward landscape. The steep rocky formation gradually levels into a gentle reef slope inside a narrow bay on the west side of the island.

The rocky headland makes up one third of the dive site with crevices and substrate that house a variety of marine life. This includes moray eels and marble groupers. Macro organisms along the rocky landscape include pipefish and nudibranch. The coral reef in the remaining parts of the dive site consists of table corals on the reef top, branching acropora on the reef flats and massive coral heads (porites) on the front reef slope.

Vast areas of rubble on the reef crest are also known as current beds where rubble is deposited into the bay as a result of current eddies that bring in the debris from upstream. This in turn becomes a habitat for shrimp gobies, triggerfish and a few species of shellfish.

Beyond the rubble bed, there are scattered coral heads on a white, sandy bottom. A colony of Yellow Margin Triggerfish nests in the rubble area. Titan Triggerfish are also seen in the area. During the course of a dive these areas should be avoided. Triggerfish attacks can cause panic and add the risk of a rapid ascend.

Mooring forms are laid on the reef crest inside the bay with line and buoy to facilitate the deployment of divers and snorkelers that visit this site on a daily basis. Dives normally begin on the shallow reef slope on the west side at the mooring line.

At ebbing tide, the dive can be planned as a drift dive in moderate currents. A similar plan can also be applied to a flooding tide, as currents rarely drift southward at this site as a result of eddies created by the headlands.

Barracudas and other predatory fish are often sighted in the open water beyond the tip of the headland. On the reef, schools of big eye snappers and turtles are regularly encountered.Yellow margin triggerfish and titan triggerfish make nests in some parts of the rubble bed. Stacks of table coral in the shallower areas of this reef are a spectacular sight. The ideal conditions around Tanjung Basi make this site a popular diving spot in Perhentian.
