When deciding what to wear on a Nile cruise, keep in mind that you should dress not only for the heat, but also for the Egyptian culture. Avoid wearing very short skirts, hot shorts, or see-through clothing to respect local customs. You must cover both your legs and upper arms when visiting a mosque. It's best to dress in light, loose clothing that covers your shoulders, chest, stomach, back, and thighs, as this will keep you cool while also protecting you from the sun. A light scarf or pashmina, which is easy to wrap around your shoulders and protects you from both the heat and the cooler nighttime temperatures, is recommended. You'll be doing a lot of walking over uneven stone flooring and sandy terrain, so comfortable walking shoes are essential. It's usually best to bring sandals as well, as closed shoes can get too hot, but on board the cruise, you can dress as you would in any international hotel or resort, including your swimming costume in the pool area.
