Broadly safe for most visitors, with only routine travel precautions needed. Public health and infrastructure are well developed.
Regional breakdown
Cayenne, the capital, is where most travellers arrive and spend time. It has the main airport, government offices and the bulk of hotels. Street crime, pickpocketing and phone snatching happen in the city centre and around the market. So travellers tend to keep valuables out of sight after dark. Kourou, about 60 km west, is the home of the Guiana Space Centre and sees regular tourist traffic around launch days. The town itself is quiet, but the road between Cayenne and Kourou is a known spot for opportunistic theft from parked cars. The western border town of Saint-Laurent-du-Maroni sits across the river from Suriname. Informal river crossings by pirogue are common and bring smuggling and irregular migration through the area. Travellers who go there usually stick to the official ferry and daylight hours. Further inland, the rainforest interior along the Maroni and Oyapock rivers is remote, with limited phone coverage. Few roads and a long-running issue of illegal gold mining camps known locally as garimpeiros. The eastern border near Saint-Georges-de-l'Oyapock faces Brazil and is the other main overland route in and out. Jungle areas south of the RN2 highway are hard to reach and travellers generally only enter them with licensed guides.
Recent advisory changes
The UK Foreign, Commonwealth and Development Office publishes a dedicated page for French Guiana and was last updated on 10 December 2025. The official advisory guidance does not set a numeric level. A recent note covers dual nationals returning to the UK under the entry requirements section. The official advisory guidance does not publish a separate advisory for French Guiana. It is covered under the France advisory, which was reissued on 28 May 2025 at Level 2, Exercise Increased Caution. With indicators for terrorism and civil unrest. The official advisory guidance flags that French Guiana, French Polynesia and the French West Indies sit outside the Schengen Area and have their own entry rules. Neither the UK nor the US currently has an ordered departure in place. And no specific zone inside French Guiana is singled out for a higher warning in the main summaries right now.
What travellers should know
Most visits focus on Cayenne, Kourou and the coastal strip, where infrastructure is closest to mainland France. Euros are the currency, French is the working language, and EU roaming applies on French networks. Travellers who plan to watch an Ariane or Vega launch usually book through the Guiana Space Centre in advance. As access is controlled and spaces fill up. Beyond the coast, the interior needs more planning. Yellow fever vaccination is required for entry and is checked on arrival. Mosquito-borne illness, including dengue and malaria in forest zones, is a year-round factor, so repellent and long sleeves are standard advice. River trips to villages along the Maroni or Oyapock are usually arranged with registered operators who know the permit rules. At the Suriname and Brazil borders, travellers tend to use the official crossings at Saint-Laurent and Saint-Georges rather than informal pirogues. Road conditions drop quickly off the main RN1 and RN2 highways, and breakdown cover is worth checking before driving inland. Travel insurance that covers medical evacuation from remote areas is something many visitors add before they go.
