Angela was not "allowed" to guide us so we were told to listen to an official guide who spent about 30 minutes outside the temple! I snuck off very quickly, but even so I did not find any time to visit the 2nd temple, of Nefertari. Or the man-made dome. Or the small side chapel. This site needs 3 hours, and if I ever return I hope to stay overnight and visit it at dawn before the planes arrive!
I cannot tell from my pictures whether we did anything in the afternoon after returning to Aswan. we may well have chilled out on the promenade terrace of the Old Cataract Hotel with a Stella!
