Arrive in Aswan, where the desert meets the Nile. Visit the High Dam, symbol of modern Egypt and the vast Lake Nasser it created. Step into the granite quarry to see the Unfinished Obelisk, a monument frozen in stone. Take a boat to the island temple of Philae, saved from floodwaters and dedicated to Isis, and sail by felucca around Elephantine, the ancient frontier town that measured the Nile’s flood. As evening falls, return to the Oberoi Zahra for your fourth and final night on board, dining and reflecting as the river flows quietly past.
