The Centre Spatial Guyanais, known internationally as the Guiana Space Center (CSG), stands 60 kilometres west of Cayenne in Kourou, French Guiana, and serves as the primary launch site for the European Space Agency and the French space agency CNES. Positioned just 5 degrees north of the equator, the location offers a gravitational advantage from Earth's rotation that significantly reduces the fuel needed to reach geostationary orbit — making this one of the most efficient launch sites on the planet. Ariane 5 and Ariane 6 rockets have launched from here alongside Soyuz and Vega vehicles, delivering satellites, scientific probes, and resupply missions to the International Space Station.
Free guided tours depart Monday through Saturday at 08:00 and 13:00, taking visitors through the Jupiter Control Centre, the Ariane rocket assembly building (the BAF), and the Guyaspace Museum. The tour covers roughly 2 to 3 hours and includes bus transport around the sprawling 70,000-hectare complex. Standing beneath the Ariane assembly hall — one of the largest enclosed structures in South America — is a genuine highlight. Photography is permitted in most areas. Advance booking through the CSG visitor registration system is mandatory; walk-ins are not accepted. Tours are suspended on launch days, which are scheduled weeks in advance, so checking the launch calendar at cnes.fr before booking is essential. Weekend launches attract public spectators to the Pariacabo viewpoint near Kourou, accessible without a tour ticket. The site is busiest during European summer months; weekday mornings in the dry season offer the most comfortable conditions and smallest group sizes. Wear sturdy shoes and bring insect repellent for outdoor sections of the tour.
