I have visited delgi by purposefully to see and visit red fort. It opens at the 9: 00 AM in morning and it has some minor tickets to enter the red fort. If you wanna see whole red fort and visit musium carefully then u must have whole day. We have only 2 hours for red fort it is very short time to see red fort. We have too visit musium very quickly because of lack of time.
There are too much places too visit inside the red fort. If u wanna shoping art items then shoping bazar is also in the red fort. There are too much large area of ted fort. Two musium is must visited places of red fort. Musium has our history of india from very beginning.
