Guinea Bissau, including its capital city Bissau, has challenges concerning safety for solo female travelers. The crime rate is relatively high with incidents such as robberies and petty theft being common. Additionally, the lack of stable law enforcement presence complicates matters. However, with appropriate caution and preparation, travel can still be possible. It's crucial to remain alert, avoid risky areas especially after dark, and keep a low profile to maintain safety. Consult with your home country's travel advisory before planning the trip.
