Moulay Yacoub is generally considered safe for solo female travelers. Local culture is respectful towards women and visitors alike. However, like any other tourist destinations, it's still important to maintain awareness of your surroundings. Petty crimes like pickpocketing or bag snatching can occur, but are not a rampant issue. There is a strong police presence, providing an added layer of security. It's advised to respect local customs, dress modestly, and avoid going out alone at night. Always take reputable transportation options.
