Ravahere

Ravahere is an atoll of the Tuamotu Archipelago in French Polynesia. It is located 53 km northwest of Nengonengo Atoll and it is separated by a 2 km sound from Marokau Atoll, its closest neighbor to the north.

Marokau and Ravahere form a minor subgroup of the Tuamotus known as the Two Groups Islands.

Ravahere Atoll is roughly boomerang-shaped. It measures 20 km in length with a maximum width of 9.5 km. The shallow lagoon has a surface area of 57.5 km2, but there is no pass to enter it.
