When I was there in March, 2023, you could not get close enough to touch the Sphinx. Barricades keep the public about 100 feet from the structure.

Old disgin

We didn't use a tour guide, just did it all on our own. Using Uber was ridiculously easy, and very cheap. From the airport the our hotel right outside the Great Pyramids was $10. We didn't feel unsafe at all, at the Pyramids or in Cairo.

Yes tickets are available near the Pyramids . Which ever pyramids you want to go inside you can buy tickets accordingly. The first Pyramid tickets costs little more than the other two. But I feel you should go inside , it will be an experience of lifetime.

If do you want to enter to the fence which round the sphinx, yes you have to pay. Strongly I recommend to get the services from a TOP travel agency in Egypt so they can arrange everything for you. Be aware that the daytrip cost around 100 usd, that allow you to visit pyramids, sphinx, Memphis and Sakkara. They include water and sometimes lunch. Avoid the travel agency call Different tour, they are scammers.

Lo siento, pero no lo se, no lo he intentado.

Consiglio un operatore turistico ufficiale, non fidarsi di guide improvvisate.

For the Pyramids, you can walk right up to them and yes, you can go inside one. There is not much to see in side a Pyramid, nowhere near as elaborate as the Valley of the Kings and Queens, but come on, you have to go inside, afterall how many people do you know that can say "I've been inside a Pyramid on the Giza Plateau? The Giza Plateau is one of the great wonders of the world. As for the Sphynx, you cannot walk up to it and touch it, but that is not such a great loss after visiting and touching the Pyramids. Besides these things are better viewed from a distance as they are so enormous. Still, the walkways around the Sphynx are only a few feet from the monument - you will not be disappointed.
