When people ask me which nature outing best sums up French Guiana, I answer without hesitation: a night on the Kaw marshes. I’ve taken dozens of travellers there from Cayenne, and the same magic happens every single time. The canoe engine cuts out, silence falls, and in the beam of the lamp two orange dots float on the surface: the eyes of a black caiman. Here is my honest, detailed guide to preparing this trip, one of the must-dos of any stay in French Guiana.
Why the Kaw marshes are unique
Located about 90 km east of Cayenne, in the commune of Régina, the Kaw marshes form one of the largest protected wetlands in France. It is a mosaic of flooded savannahs, pripris (floating marshes) and water channels framed by the Kaw mountain. This nature reserve shelters a density of birds and reptiles that few places on Earth can match.
The local star is the black caiman (Melanosuchus niger), the largest predator in South America, which can exceed 4 metres. Hunted to the brink of extinction in the last century, it thrives here in one of its last great populations. Watching it at night, just a few metres from the canoe, is a moment that stays with you for a long time.
What you will observe
- Black caimans: spotted at night thanks to the red-orange glow of their eyes in the lamplight.
- Scarlet ibis: at dusk they fly back to their roosts in their hundreds, carpeting the trees in glowing red.
- Hoatzins: a prehistoric bird with a raucous cry, nicknamed the “stinkbird”, which nests in the mangroves.
- Herons, egrets, jacanas, anhingas and, with a little luck, the kingfisher and the rufescent tiger-heron.
- Howler monkeys, whose roar carries far, along with sloths and spectacled caimans as a bonus.

How a night safari unfolds
The classic outing is timed around sunset, as this is when wildlife is most active. Plan for a full day departing from Cayenne, returning late at night or the next morning if you sleep on site.
The typical itinerary
- Departure from Cayenne in the late afternoon (around 2-3 pm): roughly 1h30 to 2h drive to the village of Kaw via the RN2 then the track. A car is essential in French Guiana; bring a slightly high vehicle for the final stretch of track.
- Boarding the canoe at the Kaw landing stage, usually around 4-5 pm.
- Cruising at sunset: this is the golden hour of scarlet ibis and herons heading back to their roosts. Get the binoculars out.
- Nightfall and the search for caimans: the canoeist sweeps the banks with the lamp. Their eyes shine from over 50 metres away.
- Dinner and a night on a floating carbet for the overnight options, or a return to Cayenne for short trips.
- Daybreak (overnight option): waking in the mist, with the chorus of birds and howler monkeys, is worth the trip on its own.
Durations and formats
- Evening trip only (no overnight stay): 3 to 4 hours by canoe, returning to Cayenne during the night.
- 1 night / 2 days package: the most recommended, with a night in a carbet or hammock, dinner, night cruise and a morning walk.
- 2 days / 1 night excursion with a hike on the Kaw mountain for the most adventurous.
When to go: the question of the season
French Guiana runs to the rhythm of two seasons. The dry season, from mid-July to mid-November, is by far the best time: passable tracks, slightly less ferocious mosquitoes, and often clear skies for superb sunsets. This is what I recommend to my travellers.
In the rainy season the marshes are magnificent and very green, but the downpours can complicate the drive and the wildlife watching. Whatever the season, bear in mind that Kaw is hot and humid all year round: we are on the equator.
On the logistics side: French Guiana is a French overseas region, you pay in euros, the dialling code is +594 and the time difference is -5h in winter / -6h in summer compared with Paris. No money to change and no exotic SIM card to plan for.
Budget and booking
Prices vary by operator and package, but here are realistic ranges seen on the ground:
- Evening canoe trip (3-4h): around €50 to €70 per person.
- 1 night in a carbet package with meals and cruises: around €120 to €180 per person.
- 2-day excursion with a hike: from €200 per person.
Be sure to book well in advance: the Kaw canoeists work in small numbers and dry-season weekends fill up fast. A deposit is often required.
