Mont Tahat rises to 2,918 metres within the Ahaggar (Hoggar) massif, in southern Algérie. The country's highest peak, this volcanic formation is summited as part of a multi-day trek departing from Tamanrasset, through the mineral landscapes of the Atakor.

Why visit Mont Tahat

Tahat is not a technical climb, but an altitude experience at the heart of the central Sahara. Three elements make it a singular objective:

• The roof of Algérie: 2,918 metres, the highest point of the Hoggar massif and the country.
• A volcanic environment: peaks, dykes and lava flows of the Atakor, remnants of ancient volcanic activity.
• A rock art heritage: paintings and engravings dated between 8,000 and 2,000 BC, documenting fauna and a way of life now vanished from the region.
• Tuareg presence: the Hoggar is home to the Kel Ahaggar, whose guides lead most treks.

History and cultural context

The Ahaggar massif has been inhabited since prehistoric times. Rock shelters in the Hoggar and Atakor preserve paintings created over a long period, between 8,000 and 2,000 years before our era. These works depict scenes of herding and hunting featuring bovines, giraffes, elephants and other animals now found only south of the Sahara. They testify to a more humid climate, preceding the progressive aridification of the region.

The Kel Ahaggar Tuaregs, present in the massif for centuries, are its principal inhabitants today. Their knowledge of the terrain, water sources and routes remains essential to any crossing of the Hoggar.

What to see and do

The summit and final ascent

The final ascent of Tahat follows a rocky path and scree slopes with no major technical difficulty but with demanding elevation gain. From the summit, the view extends over the entire Atakor: volcanic spires, plateaus and sandy depressions.

Rock art sites

Several decorated shelters lie on the trekking routes. Local guides direct visitors toward the best-preserved sites, often set apart from main tracks.

Assekrem and Foucauld's hermitage

An emblematic plateau of the Hoggar, Assekrem (2,728 m) houses Charles de Foucauld's hermitage. Often incorporated into the circuit, it offers recognised panoramas of the massif at sunrise and sunset.

Tuareg bivouacs

Nights under canvas or beneath the stars punctuate the trek. The Hoggar sky, one of the clearest in the Sahara, lends itself to astronomical observation.

Practical information

• Mandatory guidance: hiking is systematically organised with a local agency and Tuareg guides. Independent travel is not feasible in the Hoggar.
• Permits and formalities: an Algerian visa is required, and the agency handles specific authorisations for the Saharan zone.
• Logistics: water, food, 4x4 transport and camping are provided by the organiser. The remoteness requires complete self-sufficiency.
• Fitness level: good general condition, capacity to walk 5 to 7 hours daily over uneven terrain and to sleep in bivouac. Altitude remains moderate, but nocturnal cold and daytime heat challenge the body.
• Duration: allow 5 to 7 days for an Atakor circuit including Tahat's ascent; some fuller itineraries may extend beyond.
• Equipment: high hiking boots, sleeping bag suited to cold nights, layered clothing, sunglasses and sun protection.

When to go

The Hoggar's climate is high-altitude desert, marked by sharp thermal contrasts.

• October to April: recommended period. Mild days (15–25°C), cool to cold nights (sometimes below 0°C in December–January), low precipitation probability.
• May to September: intense daytime heat, poorly compatible with an ascent trek. Most operators close their circuits.

November, February and March generally offer the best balance between temperature, visibility and sky quality for bivouacs.

How to get there

Access is via Tamanrasset, the main gateway to the Hoggar:

• By air: domestic flights from Algiers to Tamanrasset airport (Aguenar). This is the most practical and fastest route.
• By road: Tamanrasset is connected by road to major northern cities, but distances are considerable (nearly 2,000 km from Algiers).
• From Tamanrasset: 4x4 transfer to the trek's starting point, organised by the agency (usually a few hours on rough tracks).

To see nearby

• Assekrem: panoramic plateau and hermitage, almost always included in circuits.
• Garet El Djenoun: the "mountain of spirits", an emblematic peak of the Tefedest.
• Saharan fauna: to identify species still inhabiting the Hoggar.
• Amadror salt flats: an ancient salt depression east of the massif.
