The Guiana Space Centre (Centre Spatial Guyanais, CSG) in Kourou is Europe's primary rocket launch facility and one of the most strategically positioned spaceports on Earth. Situated at approximately 5 degrees north latitude — closer to the equator than any other major European launch site — the CSG allows rockets to benefit directly from Earth's rotational velocity, reducing the fuel required to achieve geostationary orbit and lowering the cost of satellite deployment. The centre is operated jointly by CNES, the European Space Agency, and Arianespace, and has supported the Ariane, Vega, and Soyuz launch families across decades of European space missions. From Cayenne, the journey to Kourou takes approximately one hour by car or collective taxi along the N1 coastal highway; collective taxis depart from Cayenne's central market for around 10 euros per person. The Space Centre lies on the northern outskirts of Kourou, accessible from the town centre by local taxi for approximately 15 euros. Free guided tours of the CSG run on weekday mornings and must be booked at least one week in advance through the CNES visitor service — walk-in access is not accepted. Tours are conducted in both French and English and typically take two to three hours. The itinerary covers the Ariane 6 launch complex and its flame trench viewed from secure perimeter access roads, the Soyuz launch pad used for European Galileo navigation satellite missions, active satellite integration buildings, and a comprehensive indoor exhibition tracing European space history from the Diamant rocket of the 1960s to the current Ariane 6 era. A critical practical consideration: all public tours are suspended 24 hours before and 24 hours after any scheduled rocket launch. The Arianespace launch calendar should be checked well in advance, and bookings made on a date clearly outside any known launch window. A government-issued photo ID is required at the security checkpoint. The tour involves significant outdoor walking under direct sun; sun protection, a hat, and a full water bottle are essential equipment. After the morning CSG visit, the afternoon suits a stop at the Port de Kourou in time for the 15:00 ferry departure to the Salvation Islands, allowing both of Kourou's major attractions to be experienced in a single day.

Tips for visiting
- Tours must be pre-booked at least one week in advance through the CNES visitor service — walk-in access is not permitted
- Check the Arianespace launch calendar before booking; all tours are cancelled 24 hours before and after any rocket launch
- Bring a government-issued photo ID — security checks at the entrance gate are mandatory for all visitors
- The tour is largely outdoors and exposed to direct sun; bring sun protection, a hat, and at least one litre of water
- Use collective taxis from Cayenne (around 10 euros per person) rather than renting a car if visiting the CSG only
When to visit
The CSG is open for tours on weekdays year-round. Visiting outside launch windows (check the Arianespace calendar) and outside French school holiday periods reduces waiting times and tour group sizes. The dry season from August to November offers the most comfortable outdoor temperatures.
Accessibility
The exhibition hall and some outdoor viewing areas are accessible to wheelchair users, but portions of the outdoor tour route on uneven ground around launch complexes may present difficulties. Visitors with mobility requirements are advised to contact the CNES visitor office in advance to arrange an adapted itinerary.
Frequently asked questions
How do I book a guided tour of the Guiana Space Centre?
Tours must be reserved in advance through the CNES visitor service, typically requiring at least one week's notice. Availability is limited and bookings for popular periods fill quickly.
Are tours available in English?

All visitor tours are cancelled 24 hours before and 24 hours after any launch. Travellers should consult the Arianespace launch calendar and book on a date well clear of known launch windows.
Is there public transport from Cayenne to the Space Centre?
Collective taxis run from Cayenne to Kourou town for around 10 euros per person and take approximately one hour. From Kourou centre, a local taxi to the Space Centre costs approximately 15 euros. No direct public bus serves the CSG.
Can children attend the guided tour?
