Ruined tombs cut into the cliffs overlooking the Nile. Wonderfully romantic - you'll feel you're in 'The English Patient'. No tour-groups, just you, the pillared halls, the hieroglyphs, the desert, and the views. Easy to get to with a short sail by local felucca (ask for Nassir Ramadan on the corniche by the Ferial Gardens).
On the west bank of the Nile opposite Aswan.
