Old Derj is now completely abandoned in favour of a standard modern village. The old quarters are definitely worth a stop. Its lack of fame relates to it being after the villages of Nafusa Mountains, which are more appealing. Yet, passing by on your way to Ghadames, take an hour to walk around Derj. It may not be there for much longer time.
It is nicely set above the oasis, and a few quarters still look as it did when the locals still lived here.
