Bukit Banang, 470m high, is the summit of a range of rolling hills which terminates at Tanjong Seginting.

Four radio masts stand on its summit. Several bright white lights, visible for a considerable distance, are sometimes shown near the radio masts.

A light is reported to be shown from Tanjung Seginting and Pulau Sialu.

The coast between Tanjong Seginting and Tanjong Piai, about 50 miles SE, is low and thickly wooded; abreast Pulau Pisang the coast recedes about 5 miles.
The coastal bank, as defined by the 10m curve, extends about 6 miles offshore in this bight and up to within 1 mile of Pulau Pisang.
Within a line joining Tanjong Seginting and Pulau Pisang the bottom is very uneven, being marked by isolated depths of 5.5 to 14.6m.
