Hotels and alternatives
There is a basic form of hotel here, which offers a genuine Chenini experience, where you sleep in a traditional Chenini house, called ghar. This is medium priced, but can be full.
Restaurants and alternatives
The very same place where you sleep, is also the place where you eat. Food is good and inexpensive.
Nothing. This you should do in Tataouine, where there are plenty of banks.
No public transportation, but hitching is good courtesy out here. Many travellers who visit Chenini without being part of an organized trip, rent a taxi for the return trip in Tataouine. Then they also visit nearby destinations like Douiret and Guermessa.
