Cheras is generally safe for solo female travelers. With a relatively low crime rate, especially in terms of violent crimes, many women travel here alone without experiencing any significant problems. The locals are friendly and willing to help if you encounter any issues. It's important to take standard precautions such as avoiding walking alone at night in secluded areas, and be vigilant of your belongings, as with any city. Public transportation is reliable which is an added safety feature for solo travelers. However, be aware of potential petty thefts, which are disconcertingly common in tourist sites and crowded places.
