I know its really dificult to distinguish a fake priest .
These people are know as "PANDAS" in hindi, so avoid them as much as possible. You will find them quiet alot near all religious places offering you help regarding shopping or accomodation.
Unique Suggestions: I will suggest not to give any importance to any religios priest who ask you to show the temple or asks you to offer money.
Even if unfortunately you are caught never take anything to eat that they offer even as "prasad"(offering from god). Take it and keep it with you and can later throw it.
DONOT EAT THEN AND THERE!!!
Fun Alternatives: Ignore them!! Say u donot need any guidance have viited this place several times.
Only YOU can decide where you want to go. Not the rickshaw drivers, nor the people who meet up at the train station. but oh, they will try. Of course, they can make money on you, and as much as they may need this, remember: it is YOUR trip and your decisions. Be firm. As I have already said somewhere; If nothing else helps - lose your temper!
Unique Suggestions: Don't give up!
Fun Alternatives: In general the drivers who meet up and are really eager to get you in their wagon usually have something up their sleeve. A non-english speaking driver may be more trustworthy.
You will find at the strets many holy people that come here to purify themselves and meditate. Some are real, but you will find many that come just to make “tourist shows” and eran some money with that.
Getting lost in the small alleys, especially at night is the major trap here. Always carry a map with you (even with a map you can get lost) and remember that the river is your best guide.
Too many beggers on the street. I was told that some of them are very rich but just do it for hobby.. for fun.
