How many days do you need in Cayenne?
Give French Guiana 4 days to balance Cayenne's compact historical center with mandatory day trips. Cayenne itself takes just a day, but reaching the Îles du Salut and Kourou's space center requires dedicated days due to rigid boat schedules and tour timing.
Short answer
2 days
Focus strictly on the mainland. Walk Place des Palmistes, visit the Marché de Cayenne for local spices, and explore Fort Cépérou. Spend day two at the Guiana Space Centre in nearby Kourou.
You give up: You completely miss the Îles du Salut boat trip and the Cacao Hmong market.
4 days
Covers the essential circuit. Tour Cayenne's historic core, take the full-day catamaran trip to Île Royale and Île Saint-Joseph, complete the Ariane rocket tour in Kourou, and hike Mont Saint-Marcel.
You give up: You forego deep Amazonian river trips to Saint-Laurent-du-Maroni or overnight canopy stays.
6 days
Adds a Sunday trip to the Cacao village market, a pirogue boat excursion along the Maroni River to border Suriname, and wildlife spotting in the Kaw Marshes reserve.
You give up: Only skips extreme multi-day jungle treks near the southern Brazilian border.
If you can stay longer
An extra 2-3 days allows a trip to Saint-Laurent-du-Maroni to tour the Transportation Camp prison ruins, followed by an overnight boat expedition into the Kaw Marshes to spot black caimans and exotic birds.

Common questions
Do I need a car in Cayenne?
Yes, renting a car at Félix Eboué Airport is essential. Public transit is minimal, and reaching Kourou for space tours or boat launches to Îles du Salut requires your own reliable transportation.
When is the best time to visit?
Visit during the dry season from August to November. Alternatively, come between mid-January and March for the famous Cayenne Carnival, though expect occasional heavy downpours during this brief dry window.
Can you visit the space center anytime?
No, VIP bus tours of the Guiana Space Centre must be booked weeks in advance. Tours are strictly suspended on launch days, so check the Arianespace launch schedule before planning your dates.
