Tenali is relatively safe for solo female travelers. The locals are usually friendly and helpful, and serious crimes are fairly uncommon. However, like any place, it's vital to stay aware of your surroundings, particularly in crowded or less familiar areas. There can be occasional attention or stares, but this is majorly out of curiosity rather than malicious intent. As usual, it is suggested to avoid isolated areas at night and always keep emergency contacts handy. Always respect cultural norms and dress modestly.
