Wear whatever is comfortable. It is recommended to have a sturdy pair of broken-in trail shoes, boots, or sneakers. It is preferable to dress in layers and wear clothing that will wick away perspiration and keep you dry and comfortable
Men should wear long pants. Egyptian men do not wear shorts, and you will be denied access to religious sites such mosques and churches.
Women should bring at least two shawls or long scarves. Egyptian women tend to cover up more of their bodies than women in the West, and exposing shoulders, legs can looked down upon. A shawl can easily be pulled out of a backpack to cover yourself up when appropriate. It is okay not to cover your hair, but never wear tanks or camisole tops unless you’re on the beach. If you stick to wearing long pants, a long short-sleeve shirt or a long-sleeve shirt, you will be fine.
