Tuticorin, also known as Thoothukudi, is relatively safe for solo female travelers. Like many other places, it's important to observe general safety precautions. Avoid going out alone late at night and be aware of your surroundings at all times. Most locals are friendly and eager to help, but always use your best judgement when interacting with strangers. Public transportation exists, but it may be more convenient to hire a licensed taxi or use a trusted ride app for getting around.
