Crossing the Sahara through Niger is one of the classic overland adventures — or was, until security deteriorated across the region. As of the mid-2020s, both trans-Saharan routes from Niger are effectively closed to independent travelers and extremely dangerous for any traveler. This page documents the routes for historical reference and future research.
The Algeria Route
The main route runs north from Agadez via Arlit to the border crossing at Assamaka, then continues 500 kilometres across empty Sahara to Tamanrasset in southern Algeria. The Arlit-to-Agadez section (243 km) was paved in 1980 to support uranium mining logistics; the track from Arlit north to the border is largely unpaved, and the 210-kilometre Assamaka-to-Arlit segment crosses some of the most challenging desert terrain on the continent, with almost no infrastructure and extreme temperatures.
In the overland travel era of the 1970s and 1980s, this was one of the great desert crossings. Convoys of Land Rovers and motorcycles made the run using French-erected steel marker posts (balises) spaced every 500 metres across the Ténéré. That era is over. Armed groups have operated along the route for years, French and other governments advise against all travel to the region, and the track north of Arlit is both physically and politically impassable for independent travelers.
The Libya Route
The eastern route crosses the Ténéré desert via Bilma and the Kawar oases, then continues north across the Libyan Sahara toward Sebha. This route was always more remote and technically demanding than the Algeria crossing — even in good years, the Ténéré was one of the world's harshest desert environments, and the Kawar oases were separated by hundreds of kilometres of unmarked sand. Today, with armed groups controlling approaches and Libya remaining unstable, it is not a realistic option.
Historical Context
The Trans-Saharan Highway (TAH 2) was proposed as a development project in 1962 and construction progressed in sections from the 1970s onward. Niger contains 985 kilometres of the total route, of which around 900 km had been asphalted by 2023. The highway's primary purpose was always economic — linking West African states to Mediterranean ports — rather than facilitating tourist overland travel. Agadez, the gateway city, was a historic Tuareg capital and a UNESCO-listed centre long before the highway project began.
The first motorised trans-Saharan crossing was made in 1923 by Citroën half-track vehicles from Ouargla to the Niger River. By the 1930s, a small number of adventurers were making the crossing annually. The 1970s and early 1980s were the high point of overland travel, when Africa guidebooks included detailed route descriptions for the crossing and adventurous travellers made the journey on motorcycle or in purpose-built expedition vehicles.
