Makassar is moderately safe for solo female travelers. The city is generally welcoming to tourists but you need to maintain some level of caution. Petty crimes such as pickpocketing and purse snatching do occur, especially in crowded places, so it's essential to stay attentive and keep your belongings secure. It's also advised not to walk alone at night in less crowded and poorer neighborhoods. Locals are friendly and helpful, but as in any location, it's essential to be aware of your surroundings and follow general safety guidelines.
