Be especially careful when traveling after dark anywhere in Kenya due to crime. Terrorist attacks have occurred with little or no warning, targeting Kenyan and foreign government facilities, tourist locations, transportation hubs, hotels, resorts, markets/shopping malls, and places of worship.

In 2026, Nairobi is considered a city where "high caution" is required after dark, particularly for foreign visitors. While major hubs like Westlands and the Karen residential area are relatively safe due to high private security presence, walking on the streets in the Central Business District (CBD) or near informal settlements like Kibera after sunset is strictly discouraged. Street crime, including "snatch-and-grab" thefts of phones and jewelry, as well as more serious muggings, remains a concern. Travelers are advised to use trusted ride-hailing apps like Uber or Bolt for door-to-door transport rather than walking, even for short distances. Always keep your car windows up and doors locked to prevent "smash-and-grab" incidents at traffic lights. While the hospitality industry in Nairobi is thriving, it is best to remain within the confines of well-lit, gated commercial complexes or hotel grounds during the late-night hours to ensure personal safety.
