Boundary of the Haram
As the coach drives towards Makkah, around an hour into the drive you will see two arches, this is the boundary of the haram area. Here special conditions apply to the land even when you come out of the state of Ihram.
Boundary of Makkah
After this you will see the gate of Makkah which looks like a Quran laying on a stand. When you enter the city of Makkah, know you are in the most blessed city on Earth. The sunnah is to take a bath as you enter but this is not possible due to how busy it has become.
