The *Jebel Metlili (4900 ft.), a range of hills to the N.W. of El-Kantara, scantily overgrown with scrub and alfa-grass (p. [171]), commands a splendid view of the steppe of El-Outaya (p. [278]) and the Sahara, as well as of the fringes of the Sahara Atlas as far as Jebel Ahmar-Khaddou (p. [284]). The clearness of the air and the wonderful effects of light and shade enhance the fascination of the scene. The mule-track (2½–3 hrs.) leads to the W. through the valley of the generally dry Oued Chebba and then winds up through a gorge and over the hill-side to the summit. On the way are sometimes seen gazelles and aoudads or maned sheep (Ovis tragelaphus, Arabic arwi; occasionally even at El-Kantara).

The excursion to the *Gorges de Tilatou takes a whole day, or about 5–6 hrs. only if we go by train to Les Tamarins (p. [276]), sending mules thither beforehand (provisions should be taken). Travellers from Biskra should go by the morning train to El-Kantara and proceed thence on mule-back to Les Tamarins, where they arrive in time for the afternoon train to Constantine.—The very picturesque entrance to the Tilatou valley is about 3 M. to the N.W. of El-Kantara. The grandest part of the gorge is at the Berber village (dasbera) of Tilatou, with its curious, still partly inhabited rock-dwellings. The village lies about halfway between the mouth of the river and the station of Les Tamarins.

A visit to the Maâfa Valley takes a whole day from El-Kantara, or from the Maâfa station (p. [276]), with the ride back to El-Kantara, 6–7 hrs. at least. The mule-track leads past the S. base of Jebel Groun (3905 ft.) and the small mosque of Sidi Yahia to the rock-villages of Fetatcha and Ameradsa, inhabited by the Chaouïa (see below), at the entrance to the wildest parts of the ravine. Good riders may return to El-Kantara viâ Beni-Ferah (see below).

The Aurès Mts., the Mons Aurasius of antiquity (Arabic Auras), inhabited almost exclusively by the Chaouïa (‘shepherds’), a Berber tribe, not subdued by the French until 1845, rise to the E. of El-Kantara, culminating in Jebel Chelia (7634 ft.) and Kef Mahmel (7615 ft.), the two highest peaks in Algeria. This grand mountain-region, with the wild and interesting valleys of the Oued Abdi and the Oued el-Abiod, is as yet almost inaccessible to tourists, no quarters being obtainable except by the courtesy of the French officials or of the natives. A tour here, especially in winter, necessitates almost as tedious and costly preparations as travelling in Morocco (comp. p. [97]). Better communication will, however, be provided by the new, still unfinished road from Markouna (p. [289]) to Biskra (p. [279]), by way of Medina (4780 ft.) and Aris (3842 ft.), opening up the head of the Oued el-Abiod valley, thence following the line of the ancient Roman road through the grand Ravine of Tighanimine, and descending from the zone of the cedar-forests to M’chounech and Droh, the palm-oases on the Ahmar-Khaddou (p. [284]).

A glance at the wild scenery of the Aurès Mts. is obtained by riding past the Jebel Haouidja (see below) to (10 M.) Aïn-Zatout or Beni-Ferah (about 2950 ft.), a picturesque hill-village of the Beni Ferah tribe. Strength permitting, we may ride thence to the S. to (17½ M.) *Djemmorah (quarters at the sheikh’s) and (29 M.) Branis (988 ft.), two palm-oases in the lower Oued Abdi valley, belonging to the Ouled Ziane, the only Arab tribe in the Aurès, and to (42½ M.) Biskra (p. [279]).

After leaving El-Kantara the Railway passes through three short tunnels into the Gorge of El-Kantara (p. [276]). Near the Roman bridge we obtain a striking glimpse of the Palm Oasis, which, farther on, beyond the bed of the Rivière Blanche, we survey in its full extent. Looking back, on the right, we have a fine view of the red rocks in the gorge.

Running to the S.W., generally close to the Oued el-Kantara, the train skirts the slopes of the Montagne d’Albâtre or Kef ed-Darsa, a spur of Jebel Haouidja or Jebel Kteuf, which are geologically interesting and have a splendid red glow in the sunshine.

125 M. Fontaine des Gazelles (1280 ft.) lies in a stony waste between Jebel Selloum (2569 ft.), the S.W. buttress of Jebel Haouidja, and the singular Jebel Kroubset. The small sulphur-baths of Hammam Sidi el-Hadj, ½ hr. to the S.E. of the station, used by the natives only, occupy the site of the Roman Aquae Herculis; an elliptical Roman piscina, 107 yds. in circumference, still serves as a bath. The spring (97° Fahr.) rises at the N. base of Jebel el-Melah or Gharribou (2057 ft.), noted for its rock-salt.

Nearing (131 M.) El-Outaya (905 ft.), we survey on the right the extensive steppe of El-Outaya (‘the plain’), a kind of forecourt of the Sahara, bounded on the S. by the Chaîne de Sfa (p. [282]) and Jebel Matraf. The soil is white with saltpetre in places. To the left, beyond the station is a small palm-grove.
