Krong Kaeb, also known as Kep, is generally a safe place for solo female travelers. It's a quieter and smaller seaside town known for its serenity and friendly locals. Crime rates are low, though it's always wise to exercise common sense precautions. Night travel or isolated areas are better avoided alone. Public transportation is not very reliable, hence hiring a guide or getting a taxi may be safer options. But overall, you will likely feel comfortable and enjoying your time in Kep, as long as you’re mindful about your surroundings.
