You can visit the Pyramids of Giza, the Sphinx, the Pyramid of Khafre, the Egyptian Museum, and temples like Karnak and Luxor Temples. You will also have time for activities like cruising the Nile, visiting the bustling markets of Cairo and Alexandria, taking camel rides in the desert, and relaxing on the Red Sea beaches.
