It is situated 900 km east of Tahiti and 15 km north of Hao. The atoll is 32 km long (northeast to southwest) and 10 km wide, but only 15.55 km2 of its land is above water, the rest forming the central lagoon. The surface area of Amanu's wide lagoon is 240 km2. There are two navigable passes to enter it.
Amanu has 195 inhabitants. The main village is Ikitake.
The first recorded European who arrived at Amanu Atoll was Portuguese navigator Pedro Fernández de Quirós who navigated for Spain, on 12 February 1606, while sailing across the Pacific Ocean in search of Terra Australis. However, several 16th-century Spanish cannons were found on Amanu in 1929, indicating that an earlier Spanish expedition had visited Tuamotu. Some historians notably Robert Adrian Langdon believe the cannons belonged to the caravel San Lesmes, which was split off from the Loaísa expedition which sailed the Pacific Ocean in 1526.
