Oshogbo is fairly safe depending on the precautions taken. As in many societies, it may be unique to travel as a solo female. It is important to be aware of your surroundings, not display valuable items openly, and perhaps avoid walking alone late at night in secluded areas. Make sure you have reliable transportation options available, especially during night time. It is also recommended to dress modestly to respect local customs. Oshogbo people are generally friendly and helpful, but it's always better to be cautious, as in any travel experience.
