What should I pack for an Egypt add-on trip, and does it depend on the season?

Yes — pack light, breathable clothing year-round since most of Egypt is hot and dry, but add a warm layer for evenings if you're traveling between November and February, when nights (especially in Cairo, Luxor, and Aswan) get noticeably cooler than the daytime. Comfortable walking shoes, sun protection, and a scarf or shawl for covering shoulders/knees at religious and historic sites are useful in any season.

Because this trip is scheduled around a TourMedX medical visit, also pack any medical documents, aftercare instructions, or medication your treatment requires, and check with your care team whether your recovery timeline affects how much walking or sun exposure is comfortable during your tourism days.
