Kottayam in India is generally considered safe for solo female travelers. The people are warm and hospitable, and the city is well-regulated. However, like everywhere else, it's still necessary to follow common safety measures. Avoid isolated areas at night, be careful about who you trust, and keep your personal belongings secure. Familiarize yourself with the local customs ahead of time, particularly those related to dress and behavior to ensure you show respect for the local culture.
