In 2023, Tanzania was generally considered safe for international tourists, particularly those visiting the famous Northern Circuit (Serengeti, Ngorongoro) and the islands of Zanzibar. However, travel advisories from the US and UK during that period advised travelers to "Exercise a High Degree of Caution" due to several localized risks. The primary concerns were petty crime (pickpocketing and bag snatching) in major cities like Dar es Salaam and Arusha, and a risk of terrorism in the far south near the border with Mozambique. For safari-goers, the environment was exceptionally safe, as most trips are managed by professional guides within controlled park environments. There were also health-related considerations, including mandatory Yellow Fever vaccinations for some travelers and a continued focus on malaria prevention. In late 2023, the Tanzanian government increased its security presence in tourist hubs to combat a small rise in "smash-and-grab" thefts. Overall, while the vast majority of visitors had a trouble-free experience, the "safe" label came with the caveat that travelers needed to remain vigilant in urban areas and avoid displaying signs of affluence like expensive jewelry or large amounts of cash.
