Moorea is generally regarded as a very safe location for solo female travelers. The locals are friendly and crime rates are extremely low. Common sense precautions are enough to ensure a safe journey. Always respect local customs and traditions, and don't hesitate to ask for help if you need it. The isolated nature of the islands means that the sense of community is strong, and people look out for each other. However, just like any other places, it's important to stay vigilant, especially during night time.
