I find Pondicherry very unsafe for girls. I went to Auro beach, few boys were drunk. They misbehaved with us and other groups as well. And I heard the same stories from other people also.
Other local people can only watch.
Local people are very non supportive. even though they understand Hindi, English, they will pretend not to have a basic knowledge.
The auto wala will charge you unnecessarily and will tell you the distance more than double.
