The fort is very big and you need time to see it as entry is restricted after 5 PM or sunset and the same is mentioned near the entry by archaeological dept of Indian govt. there are some security guards on the field in casual dress so don't try to do something silly.
when you enter , there is a Hanuman temple and you should pray to god that you get back home safe after daring a visit at this place. There is long way with ruins of fort around you and mountains , forests and some kind of negative energy , [spooky but i am saying my feeling]
There are rare chandan trees around the place and don't try to harm or steal them as it needs govt permission to trade it. see every part of fort but don't be alone anywhere inside as it feels more spooky and if you have fear of these things then don't even try because there is no lights inside and inner parts of fort and still dark in sunlight.
