Rosarito can provide a relatively safe travel experience for solo female travelers. However, like traveling in any foreign country, it is important to stay vigilant and be aware of your surroundings. While locals are generally friendly and helpful, there is some risk of petty crime such as pick-pocketing or scamming in tourist areas. Therefore, it's advisable to not display expensive belongings and to keep your possessions secure at all times. Nighttime safety may vary, so avoid walking alone at night and stick to well-populated areas. There's no danger in trying local restaurants and experiencing cultural activities, but make sure you're not doing this alone at night. Always let somebody know about your travel plans for the day and use only authorized taxis or trusted transportation methods. Please note that your safety also heavily depends on your personal behavior and precautions.
