The coco de mer holds a record no other plant can touch: it grows the largest, heaviest seed on Earth. A single nut can weigh up to 25 kilograms, which is roughly the weight of a six-year-old child. According to the Royal Botanic Gardens, Kew, this giant double coconut also measures up to half a metre across.
What makes the story stranger is where it actually lives. The palm grows wild on only two islands in the Seychelles, Praslin and Curieuse, and nowhere else on the planet. That tiny range is exactly why people cross the Indian Ocean to see it.
In this guide you will learn what the coco de mer really is, where to find it, and how it got its odd name. We will also cover the export rules, the price, and how to plan a visit to the forest where it grows. By the end, you will know whether bringing one home is even possible.
What Is the Coco de Mer?
Botanists know this palm as Lodoicea maldivica, a species that does everything slowly and on a giant scale. It produces the biggest seed in the plant kingdom, some of the longest leaves of any palm, and individual trees that live for centuries. Before we get to where it grows, it helps to understand what sets the coco de mer apart.
Size, Weight, and What Makes It a Record Breaker
The seed of this palm is the heaviest in the world, weighing up to 25 kilograms according to Kew. Each nut reaches about half a metre in length and has a distinctive two-lobed shape. For comparison, an ordinary coconut rarely passes 2.5 kilograms.
The records do not stop at the seed, though. Male plants produce catkins up to a metre long, the longest flower structure of any palm, and the leaves can span several metres. Here is an odd detail worth knowing: the pollen is said to smell faintly of basmati rice, a quirk noted by researchers studying how the species reproduces.
Why Does the Coco de Mer Have That Shape?
The shape is the reason the double coconut became famous long before science could explain it. The mature nut resembles a woman’s hips and lower body, which fed centuries of myth and its old reputation as a fertility charm. That resemblance is just a coincidence of growth, not design.
Function, rather than symbolism, drives the size. A seed this large carries a huge food reserve, which lets the seedling survive on the poor, shaded soils of the palm forest. As Kew explains, this is one of the slowest and most resource-heavy reproduction strategies known in plants.
Where Does the Coco de Mer Grow?
Here is the part that surprises most people: the coco de mer is endemic to just two small islands. You will not find it growing wild anywhere else, which makes the Seychelles its only natural home. Two sites hold the populations that matter.
Vallée de Mai on Praslin Island
Сайт Валле-де-Май на Остров Праслин is the heart of the coco de mer’s range and the easiest place to see it. This palm forest was inscribed as a UNESCO World Heritage Site in 1983 and is managed by the Seychelles Islands Foundation. UNESCO describes it as a surviving remnant of the palm forests that once covered the islands.
Walking through it feels like stepping into an older version of the planet, with tall palms filtering the light overhead. Thousands of trees grow here, alongside rare wildlife such as the Сейшельский черный попугай. We suggest setting aside at least two hours to take it in properly.
Curieuse Island and Wild Populations
The second wild population grows on Остров Курьез, a small island just north of Praslin. Curieuse sees fewer visitors, so the double coconut here feels more remote and untouched. The island is also famous for its giant tortoises and is reachable on a day trip by boat.
Beyond these two islands, every other specimen you see was planted by people. According to the IUCN, only around 8,000 wild mature palms remain, which is why both sites are guarded so closely. That small number explains a great deal about the rules we will cover next.
How Did the Coco de Mer Get Its Name?
The name coco de mer means “coconut of the sea,” and it comes from a misunderstanding that lasted for centuries. Long before anyone found the palm, sailors across the Indian Ocean kept pulling strange giant nuts from the water. Some drifted as far as the Maldives, which is how the species earned its Latin name maldivica.
Without a tree to explain them, people simply invented one. The popular belief was that a mythical tree grew on the seabed and dropped its fruit into the ocean, hence “coconut of the sea.” As Britannica notes, the truth only emerged in 1768, when explorers reached Praslin and found the palms growing on dry land.
Did you know the nuts that washed ashore were once worth more than their weight in gold? European nobles paid extraordinary sums for a single nut, convinced it carried magical and medicinal powers.
Is the Coco de Mer Protected?
Given how few wild palms are left, the coco de mer is one of the most tightly regulated plants you can buy. Seychelles law and international agreements together control every nut that leaves the islands. Here is what that looks like in practice.
CITES Regulations and Export Rules
The Lodoicea maldivica is listed under CITES, the global convention on trade in endangered species, and is classed as Endangered on the IUCN Red List. Because of that, you cannot simply collect a nut and carry it home. Every legal export is tracked through a permit system run by the Seychelles government.
Each genuine nut comes with a numbered government permit and an identification tag, sometimes called the nut’s “passport.” Exported seeds are always hollowed out and cleaned, so they can never germinate. Buying from a licensed vendor is the only way to get this paperwork.
Can You Buy a Coco de Mer and Take It Home?
Yes, you can buy a coco de mer legally, but only a prepared, empty nut with the correct documents. Prices run high, often several hundred euros, because supply is tiny and demand is steady. Licensed shops and the Vallée de Mai itself are the safest places to buy.
Steer clear of any nut sold without a permit, however cheap it looks. Customs officers know the rules, and an undocumented seed can be seized, with fines to follow. One quick tip: keep the permit and tag together with the nut in your hand luggage for the flight home.
Visiting the Vallée de Mai: What to Expect
Seeing the coco de mer in its natural forest is the reason many travelers add Praslin to a Seychelles trip. The Vallée de Mai is compact, well marked, and easy to cover in half a day. A little planning makes the visit smoother.
Trail Options and How Long the Visit Takes
The reserve has three main trails, ranging from about one to two kilometres, with the shortest loop suitable for almost anyone. Most people spend between one and two hours among the coco de mer palms. The paths are clear, though the terrain includes some gentle slopes and steps.
The park opens daily from 8:30 a.m. to 4:30 p.m. and closes only on 25 December and 1 January, according to the Seychelles Islands Foundation. Entry costs around SCR 450, which funds conservation here and at the remote Aldabra Atoll. We suggest arriving early to beat both the heat and the tour groups.
Best Time of Year to Go
The Seychelles stays warm all year, but the drier, breezier windows are easier for walking. April to May and October to November usually offer the best mix of weather and smaller crowds. These shoulder months fall between the two monsoon seasons.
December to March brings the heaviest rain, while the trade winds peak around July and August. The forest stays open regardless, so a coco de mer visit works in any season if you accept the odd shower. Either way, bring water, light clothing, and proper shoes.
Where to Stay Near the Coco de Mer Forest
Staying on Praslin itself puts the palm forest on your doorstep. Many travelers, though, prefer to base themselves on the main island of Маэ and treat the Vallée de Mai as a day trip. The Cat Cocos fast ferry links the two in about 75 minutes.
For a Mahé base, STORY Seychelles sits on Пляж Бо Валлон, roughly ten minutes from the capital and well placed for ferries to Praslin. You can spend the morning with the coco de mer palms and be back on the sand by evening. It is a practical setup if you want one resort plus easy island hopping.
Worth the Trip on Its Own
Few things in Seychelles feel as genuinely singular as standing in the Vallée de Mai. The forest is older than most countries, the palms tower above you, and the whole place operates on a timeline that has nothing to do with yours. It is quiet in a way that most protected sites are not, partly because Praslin itself never gets overcrowded.
Whether you visit from Mahé on a day trip or stay on the island for a few nights, give yourself enough time to walk slowly. Read the interpretive signs, look up, and pay attention to the smaller details like the black parrots and the gecko species you will not find anywhere else on earth.
There are plenty of reasons to visit Seychelles, but the coco de mer is one you will not forget.
