Kep is quite safe for solo female travelers. Local people are generally welcoming and friendly. However, like any other travel destination, it is important to be vigilant at all times. Always be aware of your surroundings, especially at night. Street crime is quite low but it's still better to avoid dark, secluded areas. Public transportation, while generally reliable, can be crowded; it's recommended to hire a tuk-tuk or a driver for an entire day instead.
