Aqaba is considerably safe for solo female travelers. Like in any city around the world, it's important to keep your wits about you, but the level of safety is typically high. Local people are generally friendly and welcoming to foreigners, often going out of their way to assist or guide tourists. Particularly, gender-based harassment cases are low. However, cultural sensitivity, including dress code is important. Try wearing clothes that cover most of your skin to respect local norms and values. Always be vigilant, particularly in crowded places to avoid petty thefts.
