Are at all the tourist destinations. And you don’t need an ISIC card. Your standard authentic-looking laminated student ID will do.
The discounts are substantial too. For example, the Pyramids are pretty typical:
- Adult: 60 EGP
- Student: 30 EGP
- Egyptian: 2 EGP
That last one isn’t advertised in English. You need an Egyptian residency card to get it.
