Tozeur is one of the main destinations in the south of Tunisia. It's not so much the plaec to get out into the Sahara but a great place to see an oasis. Also the old town (Ouled el Hadef) is a interesting look into medieval life in the Oasis town. Tozeur is also a good jumping off point to visit the mountain oases of Tamerza, Mides, and Chebika as well as the Mos Espa Star Wars film site.
If you like the idea of experiencing an oasis with lush palm trees and vegetation in the middle of the Sahara desert, this is the place for you!
We spent less time in Tozeur than originally planned. It definitely has its charm but is short on sights and a bit less impressive than other places we visited in Tunisia. Out of the way and not quite worth the diversion unless you have a lot of time.
