the biggest temple in south india is here. It's fascinating, especially early morning and evening when it's crowded for "poja" (Holy ceremony)

#Athers-Trichirupaly- has some famous temples. Also airport for flights to Sri-Lanka.

SAFTY IN GENERAL
India is not a violent country compared to S. America, middle East, etc.
There is a very low chance of getting heldup but it's still good idea to avoid walking late at night in big cities or doggy areas.
There are many poor people and there are some thieves so lock your room with your own key. be sure not to leave your backpack alone or unlocked on public transportation. Be careful of pick-pockets in crowded places. Stay away from religion/politically tense areas!!!! The most dangerous possibility of being robbed in India is by being cheated when drugged. Don't drink or take food that been offered by strangers! There are always some stories about people who make new friends on the train, accept a drink, and wake up a day later without money.

WOMEN'S SAFTY
Indian society is very traditional. I recommend that women dress and behave modestly (shoulders and legs covered), this will reduce the problem of sexual harassment and attention. In the bigger cities you are more likely to see local women in Western style dress. Indian woman never smoke or drink in public. Don't shake man's hand, "namaste" position is well respected and shows that you have made an effort to imitate local custom. Indian women never look directly at the man eyes or sit beside an unfamiliar man on public transport. Young unmarried woman will never walk alone in the street or with a male friend (if you travel with a man It's a good idea to say that he is your husband). Be firm with any man that bothers you. Don't give him any encouragement. And...take it easy.
