They do have a counter to store the bags, mobiles, bets, footwear etc. While I did not experience any rude behavior, there are lot so touts who will tell you that they will show the place around at a very nominal fee. What they do is put you on to a pandit indie who will fore you to do some rituals etc. etc. Be aware and beware of this.

Hi come out of the temple take a left turn and turn again left. 50 odd feet away you will find a small room and adjacent that there are steps going up. If take the steps, you will be on top of that room. You can capture some good pictures from there. All the best.

None as such. However since the local people hold this temple at the highest esteem, it is advisable one should have the attire to enter a traditional temple. And also shoes, mobile and camera are not allowed. Leave that with your car.

Yes Locker is available outside

Darshan timings is from 6AM to 7PM.

No you cannot go inside if you are not Hindu but ask someone for the "platform". This is the only place where you can see the temple from "above" and take nice pictures. A local will ask you to sign a book a do a donation (of course). Give Rs.200 and he will be happy. He will probably walk you along a bit and explain a few things. Giving more would be too much to my knowledge of Odisha after 2 weeks. I guess more tourists give too much as it's probably the first site they visit and have to pay.

Strictly prohibited..including camera.
