French Guiana, more than 95% covered by Amazon rainforest, is one of the finest hiking grounds in all of the French territory. Here, walking is far more than racking up miles: it means immersing yourself in a dense equatorial wilderness, listening to the distant calls of howler monkeys, crossing paths with electric-blue morphos and emerging, at the bend of a trail, onto a blackwater creek or a viewpoint over the ocean. The good news is that around Cayenne and Kourou you’ll find plenty of waymarked trails, accessible even to beginners, without having to venture for days into the deep forest. Here are our favorite routes, from the easiest to the most demanding, with all our tips for hiking with peace of mind under the equator.
Why Hiking in French Guiana Is a One-of-a-Kind Experience
Hiking in French Guiana is, above all, an immersion in the Amazon rainforest, one of the richest ecosystems on the planet. Over just a few kilometers, you pass through very different settings: terra firma forest, mangroves, savanna, the edges of creeks. Wildlife is everywhere, discreet but present: agoutis, sloths, toucans, macaws, and an endless array of insects and amphibians.
What sets walking apart here is the equatorial climate. It’s hot (often 26 to 32 °C), the air is very humid, and the forest canopy limits airflow. A hike that would feel easy back in mainland France therefore demands more effort and more water. The reward, though, is immense: you often have the trails all to yourself, in a silence broken only by the sounds of the jungle.
The other advantage is how close everything is. From our accommodations along the coast, most of the finest trails are within less than an hour’s drive. No need to organize an expedition: half a day is enough to live a real Amazon adventure.
Easy Trails Around Cayenne and Rémire-Montjoly
To get started, or to hike as a family, several waymarked loops offer an excellent introduction to French Guiana’s wilderness without any technical difficulty.
The Rorota Trail (Rémire-Montjoly)
This is the must-do near Cayenne. This loop of roughly 5 to 6 km winds around Rorota Lake, through a well-shaded humid forest, before climbing to a viewpoint overlooking the Atlantic Ocean and the Salvation Islands in the distance. The elevation gain stays moderate and the path is well maintained. It’s the perfect chance to spot sloths and squirrel monkeys in the canopy. Allow 2 to 3 hours of easy walking.
Habitation Vidal and the Beaches of Montjoly
On the Rémire-Montjoly peninsula, the former Vidal sugar plantation reveals itself along an easy coastal walk that blends historical ruins with the seaside. You can combine it with a stroll along the long beaches of Montjoly, especially magical during the sea turtle nesting season (from March to July, while scrupulously respecting the guidelines on keeping quiet and discreet).
The Fourgassié Trail (Matoury)
A stone’s throw from Cayenne, this trail leads to a refreshing waterfall on the Fourgassié creek. The out-and-back route crosses a beautiful terra firma forest. Manageable for most walkers, it gets slippery after rain: shoes with good grip are strongly recommended.
Hikes Near Kourou
The Kourou area, famous for its Space Center, hides superb trails rich in history and biodiversity.
Monkey Mountain (Montagne des Singes)
Overlooking Kourou, the Montagne des Singes offers several well-waymarked forest loops, each a few kilometers long, over gentle terrain. The name is well earned: with a little patience and quiet, you stand a good chance of hearing, or even spotting, howler monkeys and capuchins. It’s a great place to get a first taste of walking through equatorial undergrowth, just a short distance from town.
The Annamite Penal Camp (Bagne des Annamites)
Deep in the forest, along the road to Kourou, the Bagne des Annamites is an interpretive trail as moving as it is enlightening. You make your way among the remains of the relegation camp where Indochinese prisoners were held in the 1930s. The walk, flat and short, blends colonial history with nature reclaiming its ground. A powerful visit, best experienced with the explanatory panels or a guide.
Into the Deep Forest: The Cacao, Trésor and Voltaire Falls Trails
When you’re ready to take it up a notch, several sites plunge you into a wilder French Guiana.
- Cacao Trails — This Hmong village in the inland highlands is surrounded by forest tracks and trails that follow creeks and slash-and-burn clearings. The atmosphere here is more remote, ideal for observing tropical flora and finishing with the famous Sunday market.
- Trésor Nature Reserve — On the foothills of Kaw Mountain, this reserve features a maintained botanical trail that reveals the extraordinary richness of the forest: palms, tree ferns, lianas, brightly colored frogs. A must for understanding the Amazon ecosystem.
- Voltaire Falls (western French Guiana) — More demanding because of their remoteness, these spectacular waterfalls are earned at the end of a forest trail. A swim at the foot of the falls rewards the effort. Plan real transport logistics and, ideally, a guide.
For these more distant outings, a suitable vehicle is often essential: be sure to book a car rental before you set off, as public transport doesn’t serve these sites.
Which Level to Choose and When to Go?
Hiking in French Guiana caters to every profile, as long as you pitch your ambition right.
- Beginner / family: Rorota, Habitation Vidal, Montagne des Singes, Bagne des Annamites. Short, waymarked loops with no major difficulty.
- Intermediate: Fourgassié, the Cacao trails, the Trésor reserve. Wetter terrain, sometimes slippery, slightly longer durations.
- Advanced: Voltaire Falls, the Tabular Summit, multi-day treks in the deep forest, always led by a professional guide.
As for timing, aim for the dry season, from July to November: the trails are less muddy, the creeks more passable and the showers less frequent. During the rainy season (December to June), the paths become very slippery and some creeks can be in flood. Whatever the time of year, set off early in the morning: you’ll enjoy the relative cool, more active wildlife, and you’ll avoid the late-afternoon storms.
Gear and Safety in an Equatorial Environment
Heat and humidity are the main challenges. Serious preparation makes all the difference between a great outing and a mishap.
- Hydration first: carry at least 1.5 to 2 liters of water per person for a half day, more in the deep forest. Drink regularly, without waiting until you’re thirsty.
- Protection from the heat: walk during the cooler hours, take breaks in the shade, don’t push too hard. If you feel dizzy, nauseous or get a headache, stop and cool down immediately.
- Suitable footwear: walking shoes that grip on wet ground are essential. Trails quickly turn into a skating rink after rain.
- Light, covering clothing: opt for thin long sleeves and light trousers to protect yourself from mosquitoes, ticks and stinging plants.
- Insect repellent and first-aid kit: effective repellent, bandages, disinfectant. Malaria is still present in certain remote areas: ask about prophylaxis before a trek into the deep forest.
- Wildlife: observe but never touch. Stay on the trails, and watch where you place your feet and hands (snakes, ants, hornets). The vast majority of animals will flee before you even see them.
- Weather and navigation: check the forecast, tell someone close to you about your route, and never hike alone in the deep forest. Off the waymarked trails, a local guide is mandatory for your safety.
Finally, respect the rules of the nature reserves: pick nothing, leave no trash, and stay on the authorized paths. This forest is a fragile treasure.
Where to Stay Between Hikes?
To reach all these trails easily, set up your base camp on the coast, in Cayenne or Rémire-Montjoly, just minutes from the Rorota and a short distance from Kourou. That way you enjoy the comforts of town and quick access to nature.
