Batna is a gateway town in eastern Algeria, sitting at over 1,000 metres on the northern edge of the Aurès Mountains. The town itself is functional rather than charming — the French built it as a military camp in 1844 to control the roads running south into the Sahara — but the surroundings are the reason to come.
The Roman ruins of Timgad, one of the best-preserved Roman cities in North Africa, are just 35 kilometres east. The Aurès Mountains themselves offer dramatic gorges and Berber villages rarely visited by outsiders. Also within easy reach is Lambèse, the Roman legionary fortress at Tazoult, which sees a fraction of the visitors that Timgad does. The Musée de Batna provides useful context for both sites before you head out. Constantine and the Tunisian border are both within easy reach. At this altitude, the climate stays pleasant through the hot summer months when the lowlands become stifling.
