Egypt’s trove of ancient ruins is more than anyone could take in in a single lifetime. You may start with the Great Pyramid of Giza, the largest pyramid in the world, with its stuffy interior and imposing façade. And you may choose to marvel at the mystery of the Sphinx, whose origins and maker are still unknown. Or you may choose to study Egypt’s lesser-known ancient Christian and medieval Muslim sites with their labyrinths of churches and mosques. In a land where the sand meets the sea, Egypt’s wonders are endless. These are our favorite roundtrips, as with most of our trips, the itinerary can be tailored around your preferences.
