For travellers with time, a vehicle and a taste for genuine adventure, the overland route from Morocco through Mauritania into Senegal is one of Africa's classic journeys — tracing the old salt caravan roads south along the Atlantic edge of the Sahara. It's not a trip to improvise; here's the route, the borders, and what to plan for.
Route overview and distances
The core route runs Agadir → Dakhla (Western Sahara) → the Guerguerat border → Nouadhibou → Nouakchott (Mauritania) → the Diama border → Saint-Louis → Dakar (Senegal), covering roughly 3,000km one-way. Most independent overlanders allow two to three weeks minimum to do it without rushing.
Leg 1: Agadir to Dakhla
This first stretch runs down Morocco's Atlantic coast through Western Sahara, on well-maintained tarmac roads, with Laayoune and Dakhla as the main stopping points. Distances are long and towns are spaced out, so plan fuel and rest stops accordingly.
The Guerguerat border crossing step by step
The Guerguerat crossing between Western Sahara and Mauritania involves exiting Moroccan-administered territory, crossing a stretch of no-man's-land, and entering Mauritania — historically a slower, more bureaucratic process than most Moroccan border crossings, with fixers commonly assisting with paperwork on the Mauritanian side. Border procedures and openings can change, so check current status before travelling, ideally through an operator with recent, on-the-ground experience.
Leg 2: Nouadhibou to Nouakchott
From the border town of Nouadhibou, the route continues to Mauritania's capital, Nouakchott, through open desert landscape. This stretch is also where travellers can detour inland toward Atar and the Richat Structure (see our dedicated guide) if time allows.
Leg 3: Diama border into Senegal, Saint-Louis, Dakar
Continuing south from Nouakchott, most overlanders cross into Senegal via the Diama border post near the Senegal River, arriving first at the historic colonial town of Saint-Louis before continuing to Dakar.
Visas, insurance and paperwork
Visa requirements for Mauritania and Senegal vary by nationality and change periodically — verify current rules with official sources before departure. Vehicle documentation (carnet de passage where required), third-party insurance valid in each country, and International Driving Permits are typically needed; a guide or operator with current regional experience can save significant time and stress on paperwork.
Araouane and the old salt caravan routes
Deeper in the Malian Sahara, the legendary town of Araouane once sat on the historic salt caravan routes linking Timbuktu to the Mediterranean — though current regional security conditions mean this specific area is generally not recommended for independent travel; check current advisories carefully before considering any route through northern Mali.
Doing it with a guide vs alone
Experienced overland travellers with proper vehicle preparation do complete this route independently, but doing it with a guide or as part of an organised convoy significantly reduces the logistical and administrative burden — particularly around the Guerguerat crossing and Mauritanian permits — and adds local knowledge of current road and security conditions that's hard to replicate from abroad.
