Îlot Leroue (Leroue Island) is a small islet bordered by a coral reef, located in the large southern lagoon of New Caledonia. It is a natural site, far less crowded than some other islets closer to Nouméa. Snorkelers will enjoy its unspoiled reef drop-off, where colorful fish, turtles, as well as reef sharks can be seen.

How to get to Îlot Leroue snorkeling spot?

Leroue Island is located in the large southern lagoon of New Caledonia, about a 1:30-1:45 boat ride from Nouméa. This islet is less easy to reach than other islets closer to Nouméa and therefore more visited, such as Îlot Amédée or Îlot Signal.

You can get to the islet with your own boat or with a taxi boat, which can drop you off on-site under certain conditions (especially when the boat is full – check with the operators in Nouméa). Catamaran cruises in the lagoon sometimes also stop there. A small pass allows boats to reach directly the islet.

Water entrance for snorkeling Leroue Island

Get into the water from the beach, facing the small pass that provides access to the reef drop-off. Be careful of the tide on the way back, because you must also use the pass to return to the islet.

Leroue Island’s reef snorkeling exploration tips

Swim through the pass to reach the reef drop-off, which you can follow to the south for around 200m (see map above). The drop-off is more or less steep, and offers a beautiful diversity of underwater reliefs, including outcrops, walls, and canyons. The depth at the foot of the drop-off varies from 10ft/3m to 30ft/10m depending on the area.

School of silver fish
Schools of thousands of silverfish find a shelter near the reef.

The reef, made up of dozens of hard coral species (mainly from the Acropora genus) is quite healthy. Around the drop-off, you will spot many fish found on the Caledonian coral reefs, including damselfish, butterflyfish, clownfish, and countless other species.

On the outer reef, you may also have the chance to encounter a green sea turtle or a whitetip reef shark, two species quite common along Leroue Island’s shore.
