Located 143 kilometres (89 mi) northwest of Pitcairn Island, at 23°55′26″S130°44′03″W / 23.92389°S 130.73417°W / -23.92389; -130.73417. Oeno Atoll measures about 5 kilometres (3.1 mi) in diameter, including the central lagoon, with a total area exceeding 20 square kilometres (7.7 sq mi). There are two larger and three smaller islets on or within the rim of the atoll. Their aggregate land area is only 0.69 square kilometres (170 acres). Oeno Island serves as a private holiday site for the few residents of Pitcairn Island, who will travel there and stay for two weeks in January.
The main island (Oeno), about 0.5 square kilometres (120 acres) in area, has forest and scrub with pandanus and palm trees. It is located in the southwest part of the atoll's lagoon. There is a water tap installed on the island. The maximum elevation is less than 5 metres (16 ft). Sandy Island (or Islands) is to the northeast and may be an ephemeral island. Three smaller islets are to the south and west of the main island.
^The name is not Polynesian but Greek. The island was named after the whaling ship Œno/ˈiːnoʊ/. However, the islanders pronounce as if each vowel letter were a syllable, as in Polynesian names.

"Unless you've got your own yacht, your only chance of getting to Oeno is in January, when Pitcairners fit out two of their longboats with essential supplies and swap everyday life on Pitcairn for a fortnight's summer holiday on Oeno."
