The isolated d'Entracasteaux Reefs lie 190 km northwest of New Caledonia's main island of Grand Terre. They lie at the opposite side of the 30 km wide Grand Passage that separates them from the northern ends of the Grand Récif de Cook and the Récif des Français. The group consists of a cluster of two main atolls-like reefs and a number of smaller reefs spread over an area of around 6,400 km². Located amongst the reefs are several cays that have a combined land area of 0.65 km².
The large reef on the left (south) in the above image is the 30 km long, mostly submerged, Atoll Surprise. The perimeter of its outer reef is continuous except for in the northwest regions where it begins to break up in to smaller units, forming passages in to the interior lagoon. In this region there are two small islets of Île Leizour & Île Fabre. The western reef rim contains the island of Île Surprise. Vegetated and low-lying, these remote cays provide regionally important nesting grounds for Sea Turltes.
Situated 10 km to the northwest from the Surprise Atoll is the similar-sized Huon Atoll and its solitary island of Île Huon. More isolated at the west (top) is the smaller, crescent-shaped, Atoll du Portail.
