My golden temple visit was on September 2016, It was a life long experience. Even though thousands of people are present and all are in good discipline.
People of Punjab are amazing, they follow their religious values in their life. People should remove their footwear and clean their foot with the water before entering the temple.
And the part of the Amritsar temple is below.
There is no security harassment
There is no restriction to click photo in temple premises.
