Unguja Ukuu is located on a small peninsula in the mid-southern part of the island of Unguja, commonly known as Zanzibar (Fitton, this volume). The site borders the sandy seashore to the west and south; a creek lined with mangrove trees lies to the east (Map 3, p. xxiv). On the landward northern side, which today is traversed by the motor road linking to the island network, lies a predominantly coral rag landscape. The beach is sheltered in a small bay with coral islets, providing a perfect early-type anchorage for the site, for communication with the nearby mainland coast and wider Indian Ocean interactions.
