Ari Atoll is the second westernmost atoll of the Maldives, only after Maamakunudhoo Atoll. It is oblong in shape, 89 km in length by only 31 km in breadth. It contains some 50 islands, generally small, which lie mainly along its eastern fringe. Its features are intermediate between Maalhosmadulhu and North Malé atolls.
Except for a small barrier reef in its southern end, it is shaped by a succession of large, separate oval reefs, like the large atolls in the North, with a clear rim of large faru to the east.
In the interior the general soundings are 30 to 40 fathoms (55 to 73 m), with mud and sand. In places its lagoon contains small reef-patches, but it is generally dotted with many large coral reefs, some of which remain submerged even at low tide.
