Another good breakfast, and then you can either spend the fourth day of your tour leisurely exploring Cairo on your own, or you can enjoy an optional tour to Alexandria.
If you choose the tour, you will see the historical Qaitbay Citadel, which was created in the 15th century by Sultan Qaitbay. This was a stronghold in the Mediterranean Sea, and it had significant relevance in Egyptian history. Sultan Qaitbay built the citadel on the site of the ancient lighthouse of Alexandria. This optional tour will also take you to the Catacombs to see the amazing cemetery that was cut from rock.
No matter what you choose to do with this final day in Cairo, you will return to your hotel in the evening for another relaxing night.
