St Thomas Mount 

This place is really something that will give you goosebumps. Located away from the main city, every passing second seems to be suffocating and even in the daylight, one can feel something awkward with the place. You should never try it out if you are weak at heart. All these are popular places in terms of spookiness and people sometimes visit them to find out the real experience. However, all you need to remember is that you should proceed at your own risk!
