São Tomé is generally considered to be a safe destination for solo female travelers. The crime rate is relatively low and people are friendly and welcoming, but, like anywhere, it's always advisable to take common sense precautions. It's recommended to respect local cues regarding dress and custom, avoid venturing out alone at night, especially in isolated areas, and remain conscious of your belongings at all times. Be aware that while violent crime is rare, petty theft can occur. Public officials are generally cooperative if you find yourself in need of assistance.
