Djanet is a charming laid back place, as close to the classical picture book oasis as it can be. There is nothing of special interest there, however the neat little town tucked away in a winding valley among low hills, with it's large palmeries, conveys a very pleasant, peaceful air. This feeling is retained even after returning from a longer trip into the deep desert, in contrast to most other saharan towns these days, that convey that 'return to civilisation' feeling with all the bustling, noise and polution that one strives to leave behind.
There are four main points of interest for a traveller:
Djanet hosts a multitude of small travel agencies who all live off organising treks to the plateau. They usually offer some meagre accomodation at their premises. (See Agence Essendilene Voyages for one of them, we had very good experience with them both times, the first time without any pre-organisation, just turning up at Djanet.)
The offices of the Parc National du Tassili are also located in the town, together with a small museum of little interest. The office is more important however, as one must buy a ticket and photo permit to visit the Plateau.
In the mornings there is a market to buy fresh vegetables, and the local baker is conveniently open in the small hours before dawn when most treks begin, so fresh bread may be obtained at the last minute.
