Trans-African Highway — Nairobi to Addis Ababa via the Moyale Border and Northern Kenya Desert Corridor
Northern Kenya's desert gauntlet to Ethiopia.
Leaving Isiolo, the tarmac dissolves into corrugated murram and lava-rock rubble within an hour — that’s your signal that the A2 highway’s reputation is fully earned. The route north through Marsabit, across the Kaisut and Chalbi Deserts, and up to the Ethiopian border town of Moyale covers roughly 800 km of road that eats tyres, destroys bearings, and rewards the committed with landscapes that feel genuinely prehistoric. Marsabit itself sits on a volcanic massif rising from the desert floor — fuel, water, and a cold soda before pushing north. The Chalbi Desert section south of Moyale is dead flat, scorching, and utterly featureless except for the occasional Rendille camel caravan crossing your path. The border town of Moyale is split between Kenya and Ethiopia; cross the border and the road north to Addis improves significantly on the Ethiopian side.
This is a Difficult to Expert run depending on recent rains — the Chalbi floods in the long rains and becomes completely impassable. A high-clearance 4WD with reinforced sidewall tyres, dual spares, and significant water carrying capacity is essential. Security considerations in the northern corridor require checking current advisories with your government travel authority before departure; travel in convoy is strongly recommended. Best window is June through September, avoiding the long rains. Fuel at Marsabit and Moyale only — carry reserves. No cell service north of Marsabit. This is one of East Africa’s genuinely hard overland links.

Frequently asked questions
What's the minimum build needed to run Nairobi to Addis Ababa through Moyale?
High-clearance 4WD is non-negotiable — think Land Cruiser 70/80 series, Defender, or equivalent with a proper skid plate setup. Stock lifted wagons can make it in dry season, but you need dual spares minimum and a recovery kit; a soft tire 400km from help is a serious problem, not an inconvenience.
When should I run this route and what does rain actually do to the road?
June through September is the dry window and the only time most of this corridor is reliably passable. The rainy seasons (March–May and October–November) turn the Kaisut Desert sections and the stretch north of Marsabit into impassable clay and flash-flood terrain — vehicles have been stranded for days.
Do I need special permits or border documents to cross into Ethiopia at Moyale?
Yes — you need a valid Ethiopian vehicle permit (obtained in advance), carnet de passage or temporary import document, and valid visas for both Ethiopia and Kenya. The Moyale crossing has a reputation for slow processing; budget half a day minimum and have all paperwork printed and organized.
What's the hardest section and what should I actually expect driving it?
The corrugated gravel and rocky track between Marsabit and Moyale is the worst of it — relentless washboard, loose rock, and stretches with no defined road surface for km at a time. Average speeds of 30–40 km/h are realistic; push harder and you'll punish your suspension, shake loose your gear, and blow tires.
How much water do I need to carry and where can I resupply on this route?
Carry a minimum of 20–30 liters per person for the Isiolo-to-Marsabit stretch, and top off hard in Marsabit before pushing north — water sources between Marsabit and Moyale are unreliable and scarce. Marsabit is your last guaranteed resupply point for fuel, water, and basic provisions before the Ethiopian border.
