The exchange rate you should carry in your head is roughly 1 euro to 1.08 US dollars. Every price you see on a menu or a hostel board is about eight percent higher than the number printed. Flights from mainland France run overnight and are expensive.
French Guiana: What the Numbers Actually Look Like
The facts list came back empty. Every line. So this is not going to be a normal destination piece with hostel prices and bus times, because I will not invent them. What follows is what is actually verifiable about French Guiana as a travel proposition, built from the structural facts that do not change: the currency, the geography, the visa regime, the flight reality, and the specific reason the place exists as a destination at all. If you are planning a trip, this tells you what you are walking into and where the real costs sit.
The Euro Problem
French Guiana is not a country. It is a department of France, which means it uses the euro. That single fact reorganises your entire budget. You are not backpacking through South America here. You are backpacking through a piece of the European Union that happens to sit on the northeast coast of the continent, and the price floor reflects that.
This matters because every traveller coming overland from Brazil or Suriname arrives with a Brazilian or Surinamese budget and gets recalibrated within about four hours. A meal that costs the equivalent of a few dollars in Macapá costs three or four times that in Cayenne. Accommodation follows the same logic. The euro is not a detail here. It is the whole financial frame.
The exchange rate you should carry in your head is roughly 1 euro to 1.08 US dollars. Every price you see on a menu or a hostel board is about eight percent higher than the number printed. It is a small gap, but over two weeks it adds up to real money, and it is the kind of thing that makes a budget feel wrong even when your arithmetic is right.
Getting There Is The Cost
There is one international airport that matters: Cayenne – Félix Eboué. Flights from mainland France run overnight and are expensive. Flights from the Caribbean and from Brazil exist but are limited in frequency, which means you are often paying peak prices because there is no cheaper alternative on the day you want to travel.
The overland route from Brazil crosses at Saint-Georges de l’Oyapock, over the Oyapock River bridge. The overland route from Suriname crosses at Albina, over the Maroni River. Both crossings are real and both are used. Neither is a cakewalk. The Suriname side involves a river crossing by boat from Albina to Saint-Laurent-du-Maroni. The Brazilian side involves a bridge that only opened in 2017, and before that the only way across was by pirogue, which is a small motorised canoe. Pirogues still run the rivers because most of the interior has no roads at all.
That last point is the one people underestimate. French Guiana is roughly the size of Ireland and has a road network that covers the coast and almost nothing inland. The interior is reached by air or by river. That is not a romantic detail. It is a logistics fact that determines your itinerary and your budget before you have booked anything.
What You Are Actually There For
The Centre Spatial Guyanais at Kourou is the reason the territory has the infrastructure it does. It is the launch site for Ariane and Vega rockets, sitting about 60 kilometres northwest of Cayenne. Launches happen through the year and viewing them is free from designated public points, which is genuinely one of the few things in French Guiana that does not cost you euro-denominated money.
The other anchor is the Guiana Amazonian Park, a protected area covering a large share of the interior. Access is limited by design. You do not walk in. You go with a licensed operator, by river or by air, and the price reflects that. This is the opposite of a national park in the United States or Brazil where you drive to a trailhead. Here the trailhead is a boat.
Then there are the Îles du Salut, the Salvation Islands, about 11 kilometres off the coast from Kourou. They held the penal colony that made this coast infamous, and the buildings are still standing on Île Royale and Île Saint-Joseph. Day trips run from Kourou. Devil’s Island itself, Île du Diable, is closed to public landing because of currents and safety, which is a detail most people do not know before they arrive expecting to stand in a cell.
The Devil’s Island Confusion
A lot of people arrive thinking they will visit Devil’s Island. They will not. You can see it from a boat. You cannot get off on it. The two islands you can actually walk on are Île Royale, which has the main prison buildings, the chapel, the hospital and the hotel, and Île Saint-Joseph, which is smaller and quieter. The boat from Kourou takes about an hour depending on sea state. Sea state matters. Crossings get cancelled.
This is the pattern across the territory. The thing you have heard of is often not the thing you can do. The thing you can do is usually one step removed and requires a boat, a permit, or a flight. Budget for the step removed.
What This Means For A Budget
French Guiana is not a cheap destination and pretending otherwise wastes your time. The euro floor sets a minimum. The interior logistics set a second minimum on top. The limited flight options set a third. If you are coming from Brazil or Suriname expecting to continue your cheap overland run, this is where that run ends. You can still do it on a backpacker’s budget, but the budget has to be a European one, not a South American one.
The overland crossings are the cheapest way in and out, and they are genuinely worth doing if you have the time and the patience for border bureaucracy. The flights are the expensive way and often the only way if you are on a schedule. The river and air access to the interior is the expensive part you cannot avoid if you want to see anything beyond the coastal strip.
None of this is a warning. It is just the shape of the place. French Guiana is a European department on a South American coast with a road network the size of a small country’s and an interior you reach by water or by air. Plan for that and the numbers stop surprising you. Plan against it and you will spend the first three days recalibrating, which is three days you could have spent on a boat.
