I did not realize that the Great Sphinx was located so close to the Great Pyramids. You can easily see them both at the same time or on the same visit. You are not allowed to really get close to the Sphinx or to touch it. It is protected by a gate around it and security will admonish you for going past the gate. You will generally use the same guide for the Sphinx that you do for the Pyramids. If you go very early in the morning or after lunch it will not be as crowded. Egyptian citizens and students pay a lower admission fee if they have an ID. There are is a small outdoor market as you leave where you can by trinkets to remember your visit. You should be prepared to bargain to get the best deals.
