Banjarmasin is generally safe for solo female travelers; however, like most cities, it's not without its risks. Some areas may be unsafe at night and it's recommended to maintain a high level of caution at all times. Reports of local scams or low-level crime may occur. However, most locals are friendly and helpful. Always be aware of your surroundings and avoid isolated areas, particularly at night. It is also recommended to dress modestly to respect the local culture and customs, which can also help to avoid unnecessary attention.
