The Tibesti is a volcano group located north of Chad.
The place has five major volcanoes, with sub-craters and calderas. It is mainly desert landscapes, with occasional lava field...
This flight plan makes a nice tour of the volcanoes, and the interesting calderas. But there a many other areas worth to see around the path... feel free to wander !
The flight ends in the deeper desert where you will find a structure like Richat's, but smaller.
Enjoy !
