Piram Island, 11m high and composed of sand, lies with its N end about 2.8 miles SE of Kuda Point. At the S end of the island there are a few trees and a little cultivation; the NE side is fringed by a few mangrove trees.
The lighthouse is conspicuous near the middle of the island; a small village is situated close N of the lighthouse.
Reefs surround the island and extend about 2.5 miles NNE, 0.5 mile E, and 1.5 miles SSE from the island. Shoal water, with depths of less than 11m, extends about 7.8 miles SSW from the S end of the reef surrounding Piram Island.
The narrow channel between Mallock Reef and Piram Island should not be used without local knowledge as the tide runs through at a great velocity and there is very little slack water.
