We think Biskra is one of the most beautiful Algerian oases. Used by the Romans, it has date palms and the Hammam Salhine health spa at Ad Poscinam. If all this sounds appealing, plan to stay at least two nights. Also see the El Kantar Gorge, the terraced village of Rhoufi and the mosque of Sidi Okba, where the ceiling is made from woven palm fronds. 120 mi/195 km southwest of Constantine.
