On the half-day tour to the Giza Pyramids and Sphinx, travelers will visit the Pyramids of Khufu, Khafre, and Menkaure, capture stunning photos from the Giza Plateau, and marvel at the legendary Sphinx. An expert guide will share fascinating stories about these ancient monuments. Initially standing at 146.6 metres (481 feet), the Great Pyramid was the world's tallest human-made structure for more than 3,800 years. Over time, most of the smooth white limestone casing was removed, which lowered the pyramid's height to the current 138.5 metres (454.4 ft); what is seen today is the underlying core structure.
