Kasauli is a beautiful town in himachal pradesh with lots of mountains.
I travell to kasauli with my family in car and enjoyed very much in kasauli.
There are many places to see such as sunset point, dilbret trail, manki point and church.
All places are very good and enjoyable.
Now talking about safety there is not much safety on mountains only some stones are placed at the corner of mountains and at many places there is no safety at all you need to aware when you are walking on mountains.
But after all it is the best place for enjoying with and without family.
