The Sphinx occupies a prominent space on the same plateau as the Pyramids of Giza, just downhill a little and due east from Khafre’s (Chephren’s) pyramid (the middle one) but still inside the compound’s walls and gates. Visiting the Sphinx is included in the price of the same ticket that gets you into the Pyramids complex, but you may need to show your ticket again to a legit local door guy to enter the Sphinx Temple complex down below its base. Some people never wander down there, but if you do just know that the much less aggressive guy at the door there asking to see your ticket is on the up and up, unlike those after the gates and security at the main entrance.
