French Guiana is one of the last great wild territories you can explore with a French passport in your pocket. Here, more than 90% of the land is covered by primary Amazon rainforest, criss-crossed by majestic rivers and home to wildlife that few travellers ever get the chance to observe up close. Black caimans gliding through the marshes, howler monkeys heralding daybreak, leatherback turtles coming ashore to lay their eggs: here, adventure isn’t a marketing promise, it’s everyday life. In this guide, we share our pick of the best experiences to enjoy in 2026, organised by mood, by traveller type and by length of stay, to help you build a trip that’s truly yours.
The Kaw marshes, the Amazonian jewel to discover by night
An hour and a half’s drive from Cayenne, the Kaw-Roura marsh is arguably the most iconic experience in French Guiana. This vast nature reserve, one of the largest wetlands in France, is home to exceptional biodiversity. The flagship outing takes place by pirogue, at nightfall: your guide sweeps the banks with a lamp and the eyes of the black caimans light up like glowing embers on the surface of the water. It’s one of the few places in the world where this Amazonian giant, which can exceed five metres, lets itself be approached.
What you can experience there:
- A night safari by pirogue in search of caimans and anacondas.
- Birdwatching at dawn: scarlet ibis, hoatzins, herons and birds of prey.
- A night in a stilted carbet in the heart of the marsh, lulled by the sounds of the forest.
Set aside one to two days to truly make the most of the site, ideally with a night on location. To plan your outing in detail, read our dedicated article on the Kaw marshes.
Heading up the river by pirogue, at the heart of the river cultures
In French Guiana, the rivers are living roads. Travelling up the Maroni, which marks the border with Suriname, or the Oyapock on the Brazilian side, means immersing yourself in a way of life set to the rhythm of the water. Leaving from Saint-Laurent-du-Maroni, pirogues carved from a single trunk slice between the rapids (the famous “sauts”) to reach Bushinengé and Amerindian villages, heirs to rich, well-preserved cultures.
It’s a longer adventure that calls for some organisation and a reliable operator, but the immersion is total: crafts, local cuisine, swimming in the clear waters between two rapids, and nights in a hammock beneath a carbet. Depending on the time you have, you can opt for a simple half-day of discovery around Saint-Laurent-du-Maroni or a multi-day journey upriver towards Maripasoula, deep within the territory.
The Salvation Islands, the memory of the penal colony facing the ocean
About ten kilometres off the coast of Kourou, the Salvation Islands offer a striking contrast: coconut palms, turquoise water, and the history-laden remains of the penal colony. The archipelago is made up of three islands: Île Royale, the most accessible, Île Saint-Joseph and the famous Île du Diable (Devil’s Island), where Captain Dreyfus was held.
The crossing is made by catamaran or shuttle from Kourou, in about an hour. Once there, you can:
- Walk around Île Royale among colonial ruins, the remains of the penitentiary and viewpoints over the ocean.
- Watch the wildlife that’s at home here: agoutis, monkeys, and many sea birds.
- Spend a night on the archipelago to enjoy the island once the day visitors have left.
It’s an ideal day trip, perfect for blending nature, swimming and history. Our complete guide to the Salvation Islands gives you all the practical tips for the crossing.
Amazonian hikes, from gentle introductions to serious treks
The Guianese forest can also be explored on foot, and there’s something for every level. You don’t need to be a seasoned adventurer to get a taste of the Amazon: several waymarked trails around Cayenne offer a first immersion in just a few hours.
A few classics depending on your profile:
- For beginners: the Rorota trail, in Rémire-Montjoly, a shaded loop ideal for families, with sloths sometimes spotted in the trees.
- For a moderate effort: the Mahury hill or the trails of Mont Grand Matoury, with lovely viewpoints.
- For experienced walkers: multi-day treks deep in the forest, with nights in a hammock and stream crossings, always accompanied by a guide.
The Amazon rainforest isn’t something to improvise: the heat, humidity and density of the vegetation demand caution and preparation. To choose the route that suits you, take a look at our selection of hikes in French Guiana.
Wildlife watching, the great living spectacle
If you dream of wild animals, French Guiana is an exceptional place to observe them. With a little patience and a good guide, you can come across an incredibly varied array of wildlife:
- Sloths, hanging from the branches, often visible right around Cayenne.
- Monkeys: tamarins, sakis, capuchins and, above all, the howler monkeys whose roar carries for kilometres at first light.
- Birds: multicoloured macaws, toucans, scarlet ibis, and bright orange cock-of-the-rock for the luckiest.
- Caimans, kings of the marshes and riverbanks.
- Leatherback turtles, the largest sea turtles in the world, which come to lay their eggs on the beaches of the west and east in season.
When it comes to big cats like the jaguar, be realistic: it’s an extremely elusive animal, and sightings remain very rare, even for locals. The adventure lies instead in spotting its tracks and savouring the privilege of sharing its territory. That element of the unknown is precisely what makes the Amazon so special.
The Guiana Space Centre, adventure among the stars
It’s hard to imagine a sharper contrast than the one between primary forest and cutting-edge space technology. And yet, in Kourou, the Guiana Space Centre offers guided tours of its facilities, from the history of space exploration to the launch sites. French Guiana’s equatorial position makes it one of the best launch points in the world for rockets.
The holy grail, of course, is to witness a launch: the roar of an Ariane or Vega lift-off rising above the canopy is a rare thrill. The dates depend on the launch campaign calendar, which changes regularly: find out in advance and keep an eye on official announcements to try your luck. Visiting the centre remains fascinating even outside of launch periods.
When to go and how long to plan for
The Guianese climate sets the pace for adventures. The dry season, from July to November, is the most pleasant for nature excursions, trails and river outings, when water levels are easier to navigate. That said, the rainy season isn’t one to avoid: the forest is lush and the streams generous, but some tracks become difficult.
For the leatherback turtle nesting season, aim instead for the period from April to July on the western beaches, a striking nocturnal spectacle best observed in strict compliance with the guidelines.
In terms of duration, here are a few benchmarks:
- A weekend (2-3 days): the Kaw marshes with a night in a carbet, or the Salvation Islands plus trails around Cayenne.
- A week: combine Kaw, the Salvation Islands, the Space Centre and several hikes.
- Two weeks or more: add a journey upriver by pirogue and the exploration of western French Guiana, further afield.
Practical tips for a successful adventure
A few recommendations for travelling with peace of mind:
- Go through local guides and operators for the forest and the rivers: they know the trails, the wildlife and the safety conditions.
- Vaccines and health: the yellow fever vaccination certificate is required, and an effective mosquito repellent is essential, day and night.
- Equipment: closed shoes, light covering clothing, sun protection, a head torch and a way to protect your gear from the humidity.
- Getting around: the departure points for excursions are often far from the town centres. A car rental will give you real freedom to reach Kaw, Kourou or the trails at your own pace.
- Book ahead for the flagship outings in high season, as places on pirogues and shuttles are limited.
Your base camp between expeditions
After a night in a hammock or a day in the marsh, there’s nothing like coming back to comfortable accommodation to recharge your batteries.
