It is the holiest Gurudwara of all and the most important pilgrimage site. People from all walks of life, caste, religion come here everyday to pray. The temple is built wonderfully. It has engravings on walls. The names of the people who contributed monetarily for the building of temple are engraved on walls. It has 4 doors from where one can enter the Temple.
Some tips/advise for having a wonderful time in Golden Temple:-
1. Early morning visit(before 9 o'clock) and after 8 pm in the evening is highly recommended. It's less crowded during these times.
2. Carry scarf or handkerchief to cover your head. Before entering the temple make sure to cover your head and maintain it all the time while you are inside the temple premises. If you forget to bring scarf or handkerchief, you can buy one from nearby stores or collect one near shoe stand for free.
3. Free shoes stands are available. Don't pay for one.
4. Taking photography inside the temple is prohibited (though people take photos).
5. Free food/meal is available in Langar Hall(inside temple) for all 24/7, 365 days a year. Enjoy the food.
6. Respect the culture and avoid talking while inside. Maintain peace.

I will recommend visiting the temple twice. Once in the morning and another in the evening. It looks spectacular in the evening.
