Planning my first trip to Tunisia. However, I have not been able to find anything "concrete" about the portion from Tozeur to Douz to Tataouine. Most information is for those renting a vehicle, we are not. I would consider taking a 3-day tour of the area, but information on this is also limited. Additionally, what is the best way to leave Jerba Island enroute north to either Tunis or Tabarka? ANY information would be wonderful. Thank you.
