Aquarium de Lagons: From Ethereal Seahorses to Ancient Nautilus

Come with me as I take you through the underwater world of New Caledonia!  We visit the Aquarium de Lagons where you journey through several marine ecosystems.

You’ll wander through freshwater rivers, mangrove forests, coral reefs, the famous lagoon, and even the mysterious deep sea.

The first residents to greet you are a set of 3 happy, spotted rays that delighted us with their under bellies.

The aquarium is famous for its nautilus collection—living fossils that have been cruising the oceans for millions of years and somehow still haven’t upgraded their shells.

We were blessed during our visit where this giant nautilus was on full display, swimming (if you call it that) around its tank and bumping along the rocks.  

Be sure to check out my Instagram and Facebook posts with the video.

I’ve been a great admirer of nautilus shells but never had the pleasure of seeing the critter that lives inside.  What a fantastic and magical experience it was to witness this guy venture around his tank.

The aquarium also plays an important role in marine research, conservation, and sea turtle rehabilitation, helping protect the unique marine life of New Caledonia’s UNESCO-listed lagoon.

They had 4 very large sea turtles in tanks that were viewable from the top, sides, and bottom!

Seahorse Exhibit

One of the most enchanting exhibits at the aquarium is the seahorse display. Delicate, graceful, and seemingly designed by an artist with a vivid imagination, these tiny creatures drift through the water while holding onto seagrass with their curled tails.

Watching them is a reminder that some of the ocean’s most fascinating residents are also among its smallest.

Fun fact: in the seahorse world, it’s the males that carry and give birth to the babies—a role reversal that never fails to surprise visitors!

Leopard Sharks

The aquarium’s two leopard sharks are another crowd favorite. Despite their intimidating name, these beautifully patterned sharks are gentle bottom-dwellers that spend much of their time gracefully cruising their habitat.

Their distinctive spotted markings make them look as though they’ve borrowed a fashion tip from a leopard, while their calm demeanor proves they’re more interested in minding their own business than starring in a shark movie.

Watching them glide effortlessly through the water is both relaxing and mesmerizing.

Whether you’re escaping a rainy day, entertaining the kids, or simply looking for an excuse to stare at fish for an hour or two, the Aquarium des Lagons is one of Nouméa’s most fascinating attractions. Just don’t be surprised if the fish seem to be judging your life choices as you walk past.

After all, they do live in one of the most beautiful lagoons on Earth.

We visited the Aquarium de Lagons on 16 June 2026.  It was truly one of my very favorite aquariums.  Not because it is huge or modern or full of unusual creatures.  But simply because it kept it simple and made the most of the exhibits it did have like the rare nautilus, seahorses, and leopard sharks.

Los Tuneles

Los Tuneles & Finada

We embarked on a boat tour today to Los Tuneles and Finada.  We were fitted for shorties (the water is 22 Celsius), boarded our small boat apply named “Diana Cristina” and embarked on the 45 minute ride.

About half way to Los Tuneles, we came across a lava vent in the middle of the ocean.  Super remarkable to see this miniature island sprouting from the sea out of nowhere.  Of course, plenty of blue footed boobies, frigates and other wildlife had already claimed this rock as their own.

Los Tuneles, also known as Cabo Rosa, are a collective of geological, large lava formations.  Ancient eruptions sent lava underground and they formed earth tunnels.  They collapsed and gave rise to these arcs over the water where you can clearly see vegetation that comes out of the rocks. These formations range from majestic bridges, stately peaks, regal caverns, and cavernous paths.

It is absolutely one of the most breathtaking places I have ever seen.  It is so hard to describe and the photos just don’t do it justice (click here to see professional pictures).  The waters are pristine, sparkling blues and greens.  When you look under a bridge, the light shines just so that the water blends from blues to greens.

We asked how old these formations were and our guide, Alexis Flores, V from Tunel Ocean said they make an educated guess by aging the cactus.  The cactus grows a few centimeters a year making them between 1k-3,000 years old.  He places the formations for which the cactus grows on to be 8k-10k years old.

Our captain expertly drove us through the narrow passageways, in and around areas we would have never thought possible and this was during mid-tide.  He does this in low tide too.  It was inspiring, beautiful, and awesome in every sense of the word.

Blue Foot Boobies:

Lots of wildlife inhabit this area including the super cool blue footed boobies.  The older the boobie becomes, the bluer his/her feet get.  When the males want to mate they use their feet in an elaborate dance to attract the females.  The boobies are spectacular fisherman, they can dive from extreme heights, and plummet deep into the water to feed.  However, on shore, they are pretty clumsy which led the Spanish to name them “bobo” which means “clutz, clumsy, or dummy” thus their name “boobie.”

We went on a walk about across the formations to find a boobie up close and personal.  They are such strange yet beautiful birds.   They have very expressive eyes!  We also saw their cousin the Nazca boobie which is a brilliant white bird.

Alexis had to pull us away kicking and screaming as we did not want to leave this little piece of heaven.  We took a group photo and headed back to Diana Cristina.

FINADA

We found a sea sanctuary minutes away from Las Tuneles.  Alexis told we had the chance to see a variety of sea creatures, but we had no idea what was in store for us.  We put on our shorties, jumped in the water and set off on an incredible underwater adventure.  Most of the swimming was in 1 meter of water so it was not very deep.  The clarity was not spectacular, but since we were in such shallow water it did not matter.

Alexis expertly showed us the amazing wildlife roaming under the sea:

We also saw a penguin swimming in the water for a split second. It was the most impressive display of wildlife we had ever seen – all within a 45 minute swim.

On the way back to Isabela, we dropped a line in the water and caught two yellow fin tuna.  Our guides kept one and we made dinner with the other.
