Don’t wear anything too revealing in most places in Egypt. Keep it conservative unless you welcome the attention that skimpy clothing will garner. People in some cities and rural areas aren’t used to seeing much skin (even from men), so please cover up unless you’re on the beach in a coastal resort like Sharm El-Sheikh or Hurghada, where this is more the norm. In areas like Islamic and Coptic Cairo, you should respect local custom by wearing more conservative clothing.
Have a guide with you when exploring archaeological sites in the desert. You can get lost, and that’s no fun.
Don’t stay with your guide at all times, as some sites are in critical condition and have areas that are in danger of collapse.
Wear a hat or scarf and sunscreen to protect yourself from the sun when visiting in the summer.
Don’t climb or touch any of the monuments.
Don’t take pictures where you’re not supposed to – your camera’s flash can cause irreparable damage.
