There is a diffirent way to go the natural reserve from Tunis:
The bus: you take it from 'Bab Saadoun'
Louage: you take it from 'Bab Saadoun' it's a car with 5 until 8 place. When the louage is full, it begin the travel
The train: you take it from 'Palce barcelone' in the center of Tunis.
If you don't find how to go to Ghardimaou, go to Jandouba and then to Ghardimaou.
Favorite thing: In the pics, you can see 'Le serf de Berberie'. It is an endangered species. it exist only on this reserve and some ather mountain in marocco.
