Puerto Iguazú is generally considered safe for solo female travelers. Issues related to violent crime are low and the locals are friendly and helpful. However, basic precautions should be heeded such as avoiding wearing flashy jewelry, or carrying large amounts of cash. Be alert, especially at night, in less crowded areas since it can be more vulnerable to petty theft. However, the main tourist areas, particularly those around the waterfalls, are well-regulated and very safe during the day. Surrounding amenities including hotels and restaurants are well accustomed to catering to tourists and provide a largely safe environment.
