It is located in the Duncan Passage, about 9.5 kilometre northeast of Little Andaman Island.
The island is roughly bean-shaped, about 1800 m by 630 m, with a broad bay on the north side.
It is almost flat, thickly wooded, fringed by a narrow beach and surrounded by a reefs.
The central part is depressed and becomes a lake in the rainy season.
[2] By the end of the 19th century, the island was occasionally visited by the Onge of Little Andaman to catch sea turtles; one explorer reports finding huts "with neat charpoys of bamboos" capable of holding 30 people.
