The pyramids of Egypt. Has anyone been inside?

Among the Egyptian pyramids, only the three pyramids of Giza (pyramid of khufu, khalaf and Menkoala) are tourist attractions, among which only pyramid of khufu allows tourists to visit.

Visitors can visit the king's mausoleum through the corridors of pyramid of khufu. Other pyramids are closed to tourists for safety reasons, but you can take photos nearby.

Other pyramids, such as the Red Pyramid and King Zosel's Ladder Pyramid, do not recommend tourist attractions for the time being, but tourists can visit them. In other words, people can enter the pyramids, but there are only a few open pyramids, and others are absolutely not allowed to enter, so pay special attention. However, in recent years, Dr. Zahi Hawass of Egypt's Supreme Cultural Relics Management Committee ordered the reduction of tourists or the indefinite closure of the Great Pyramid. The reason is that tourists exhale too much carbon dioxide and water vapor, which makes the Great Pyramid in danger of internal erosion. ?

People who have been to the pyramid said that when he went in, he followed a man with his head down and the width was slightly wider than that of the two. Although the number of tourists is limited every day, there are still quite a lot of people, so the air is not only thin, but turbid, and there will be dizziness and nausea. ?

Therefore, many popular suggestions are aimed at people with claustrophobia and bad heart, so it is better not to go. However, people who want to satisfy the adventure and excitement can still try to go in once. After all, the pyramids are really mysterious.
