It is located roughly in the center of the harbor east of Colonia, the Yapese capital, between Pekel and Bi Islands.

It is a low island with a maximum height of about 22 feet (6.7 m), and is overgrown with tropical vegetation.

The island has local historical importance as the home of Captain David O'Keefe, an enterprising American who arrived on Yap in the 1870s, and was responsible for not only significant economic growth, but also for the depreciation of the distinctive Yapese currency, the large rai stones which became devalued after O'Keefe introduced iron tools that made manufacture of the stones easier.

O'Keefe settled on Tarang, where he had a boat landing, coal warehouse, and house.

[1] The island was listed on the United States National Register of Historic Places in 1976,[2] a time when Yap was part of the US-administered Trust Territory of the Pacific Islands.
