Spend a morning of scenic cruising along the glistening Nile River. Relax on the Sun Deck as you cruise from Esna back to Luxor. First, explore the Temple of Karnak, the largest religious complex in Egypt and one of the largest in the world, covering about 200 acres in a vast network of columns, hieroglyphics, obelisks, sphinxes, and colossi — even a lake is on the grounds. The Hypostyle Hall is a great architectural marvel and filled with its roof blocks, supported by colossal 134 columns standing at 70 feet high, with 12 larger columns standing at 80 feet high lining the central aisle. This hall is still the largest room of any religious building worldwide. After visiting the temple, journey to a museum and discover the art of papyrus making. Learn how the ancient Egyptians used this special plant that flourished in the Egyptian Delta and Nile River Valley. Made from the aquatic papyrus plant, also known as the paper plant, this unique writing material served many purposes in ancient times, from sails, cloth, food, and especially paper for important documents and texts. Afterward, visit the Temple of Luxor, constructed over centuries by Amenhotep III, Ramses II, Tutankhamun, and other pharaohs. You can then return to the ship to relax or visit the colorful Luxor Market, where you can find eye-catching piles of spices, jewelry, clothing, and irresistible smells of incense and perfumes.
