01 A 25-kilo fruit

It is worth grasping how narrow that margin is. This is not a rare species within a large country: it is a plant whose entire world fits into a valley you can walk in two hours, plus one neighbouring island. If something happens to that valley, it happens to the whole species.

The palm grows slowly and takes decades to bear fruit, and each nut needs years to ripen. That slowness, combined with a tiny range, explains why it is listed as endangered and why its trade is regulated down to the last detail.

02 Why it comes with paperwork

It is probably the only travel souvenir in the world that travels with its own registration number.

The coco de mer appears in the CITES appendices, the international convention on trade in endangered species, and is classed as endangered on the IUCN Red List. Every legal export is recorded: the nut receives an identification tag issued by the Seychelles government, which acts as its document, and the buyer obtains the matching export permit.

Tags do not circulate freely. They are allocated to private owners with registered palms and to bodies such as the Seychelles Islands Foundation, which manages the Vallée de Mai. And nuts that leave the country are hollowed out and cleaned before sale, so that they cannot germinate elsewhere: what travels is the shell, not a viable plant.

Hence the price. A legal nut costs from several hundred to over a thousand dollars depending on size and finish, fees included. And hence the warning too: if someone offers a cheap one with no documentation, the problem is not the price, it is that the nut cannot leave the country.

03 Where to see it from Victoria

You do not need to leave the capital to see the palms. The National Botanical Garden in Mont Fleuri, a quarter of an hour's walk from central Victoria, has a group of coco de mer among its collection, and it is also where many travellers buy the nut with its paperwork in order.

To see them in their forest you have to cross to Praslin, by ferry from the Victoria jetty or on a short flight. The Vallée de Mai has been a World Heritage site since 1983 and is walked on marked trails in a couple of hours. Entry cost 450 rupees in 2024; it is worth confirming the current rate before you go.

04 How to buy one properly

Three checks are enough. That the seller is licensed; that the nut carries its identification tag; and that you are given the export permit in your name, with the tag number written on it. If any of the three is missing, do not buy.

Then there is the logistics, which is no small matter: a hollowed nut is still a large, fragile object. Ask the shop how they pack it, decide whether it travels in the cabin or in the hold, and keep the permit to hand, not inside the bag you check in.

And if you end up buying none at all, that is fine too. The fact worth taking home is a different one: there is a 25-kilo fruit that grows on only two islands in the world, and this country has spent decades counting them one by one.
