Can you actually walk on the pyramids walls?

My students wanted to know if you can walk on the outside of the pyramids' walls.

Question about The Great Pyramid

The steps weren't meant to be walked on, the pyramids used to be covered in limestone so they were much smoother and couldn't be climbed on but the 'steps' today are crumbly and dangerous.

you are not allowed to walk up the wall nor are you allowed to take pictures inside however everyone does and the guy inside will wink and say its ok to take a picture wink wink a tip lol
