Hotels and alternatives
While Ghoumrassen is more than big enough to make you expect hotels here, you won't find anything. And until the ghurfa hotel of Ksar Hadada reopens, you're closest hotels are in Tataouine.
Restaurants and alternatives
There are some simple restaurants in town.
There are a couple of banks in town centre offering standard exchange services.
No public transport yet. But if you're not too late in the evening, you will be able to get a seat in a shared taxi in direction of either Tataouine or Beni Kheddache.
But this region is really the place to be with a vehicle you can control yourself. Either a taxi rented for the day, or a normal rental car (the roads out here are now in first class condition).
