Practical advice
Formalities
A visa is mandatory for French nationals. Apply at the Guinea-Bissau embassy in Paris at least two weeks before departure. A visa on arrival is theoretically possible at Bissau airport, but only if the immigration department has been notified in advance: do not count on it without prior confirmation.
Vaccination against yellow fever is mandatory upon entry into the country: the international certificate of vaccination will be requested at the airport. Preventive antimalarial treatment is essential, as malaria is endemic and active all year round. Consult a doctor specializing in travel medicine 4 to 6 weeks before your departure.
Situate yourself in relation to the political context: since the end of 2025, a transitional government has been in place following an interruption of the electoral process. Gatherings are prohibited. The Quai d'Orsay classifies the destination as "Not recommended unless there is a compelling reason". Register your trip on Ariane before departure.
Getting around
Guinea-Bissau has only one international airport, Osvaldo Vieira (OXB) in Bissau, which can be reached from Paris via Dakar (Royal Air Maroc) or Lisbon (TAP Portugal). There are no direct flights.
In Bissau, travel is done by taxi (negotiate the price before getting in) or by motorbike taxi (kandongas), which is faster in traffic jams. To the islands, only boats exist: public pirogues from the Bissau pier, slow but economical, or boats chartered faster via your agency.
On the mainland, roads are not very passable outside the main national road. A 4x4 vehicle with a local driver is strongly recommended for any trip to Cacheu or the interior of the country.
Culture and uses
Guinea-Bissau is a Muslim-majority country with a strong Christian and animist component, coexisting with remarkable harmony. The Bijago society of the islands is matrilineal: women hold significant social power, particularly in the transmission of land and initiation rites.
Respect local dress codes in the villages, especially during ceremonies. Always ask permission before photographing people. Tipping is not an institutionalized norm, but a gesture of 5 to 10% in restaurants and hotels frequented by tourists is appreciated.
Portuguese and Crioulo (Creole) are the languages of communication: a few words of Portuguese (obrigado = thank you, bom dia = hello) will be warmly welcomed. Competent English-speaking guides are found exclusively through specialized agencies.
Be prepared for the frequent power cuts in Bissau and the total lack of grid on the islands. Carry a headlamp, basic medication and enough cash for the duration of your stay.
