Sani Pass climbs the Drakensberg escarpment from KwaZulu-Natal into Lesotho, topping out at 2,876 m (9,436 ft). The road starts at 1,544 m (5,066 ft) and gains 1,332 m (4,370 ft), with gradients reaching 1:3 on the steepest hairpins. The lower approach has been tarred in stages — phase two opened in October 2022 — but the final climb between the two border posts is still gravel, and South African border control only permits 4x4 vehicles onto it. That last detail is enforced, and it is the thing to sort out before you ride there.
What the pass actually is
Sani Pass sits on the P318, the road between Himeville in KwaZulu-Natal and Mokhotlong in Lesotho, and it crosses the Great Escarpment of southern Africa at its highest section, where the Drakensberg tops 3,000 m. The pass proper — the stretch between the South African border control at the bottom and the Lesotho post at the summit — is about 9 km long. The international border itself is at the summit, not at the South African checkpoint, which means the whole climb technically lies within South Africa.
The route was used on foot by the San and later the Bantu long before it was a road. In 1922 the Basutoland government cut a two-metre track to connect Mokhotlong to the outside world, usable only by pack animals. Godfrey Edmonds, a former RAF pilot, is recorded as the first person to get a vehicle up it in October 1948, before the road existed, taking five and a half hours with a team of Basotho helpers, mules and ropes; the first vehicle to summit was a war-surplus Willys Jeep. A transport business ran jeeps between Himeville and Mokhotlong from 1949, tourists started driving up in 1956, and the first Roof of Africa Rally crossed the pass in 1966.

How much of it is tarred now
This is where most published descriptions are out of date. The upgrade of the P318 has been running in phases for nearly twenty years. Phase one covered 14 km from the P318 turnoff to the old Good Hope Trading Post, started construction in December 2006 and was completed in September 2012. Phase two, an 11.4 km section from Good Hope up to the South African border post, was environmentally approved in 2013 and ministerially approved in May 2014, bringing the total project cost to R887 million, and it was opened in October 2022.
What that leaves is the part everybody means when they say Sani Pass: the final section above the South African border post, which climbs over 900 m in about 8 km. That is still gravel, and there has been no confirmed timeline for tarring it. The practical effect is that you can now ride tar all the way from Underberg to the South African checkpoint, and then the road turns into the thing it has always been.
Riding the climb
Above the checkpoint the road narrows, the surface goes to loose stone and the gradient stops being polite. The hairpins on the upper section reach 1:3, which is steep enough that a stalled engine on a loaded bike is a real problem rather than an inconvenience. There is no barrier on the drop side of most of it. Snow and ice cover the road in winter, and in bad weather the combination of gradient and poor traction is what has killed people here — wrecks of vehicles that did not make it are still visible below the road in places.
None of that makes it unrideable. Riders report the climb as demanding but manageable in dry conditions on a bike with the right tyres, ridden slowly and deliberately, with the descent requiring more care than the ascent. What it is not is a road to attempt in the wet, in the cold, on road tyres, or at the end of a long day.
The 4x4 rule, borders and paperwork
The vehicle restriction. South Africa generally allows only 4x4 vehicles onto the pass, and this is applied at the South African border control at the bottom, which turns back vehicles judged unsuitable for the climb. The rule is written for four-wheeled vehicles and motorcycles do ride the pass, but the officials at the checkpoint have discretion and they use it. Riders arriving on a heavily loaded road bike on road tyres should expect questions. If the crossing matters to your route, ask at Underberg or Himeville the day before and be prepared for the answer to be no on the day. Coming the other way is different: Lesotho's agents at the summit generally allow vehicles of all types to start the descent, which is one reason the wrecks exist.
Border hours. Both posts operate 06:00 to 18:00. Those hours are the hard constraint on planning, because you cannot start the climb late and you cannot come back down after closing. Build the whole day around them and leave margin — the climb takes longer than the distance implies.
Closures. The pass is often closed in adverse weather and especially in winter, when snow and ice make the upper section impassable. Closures are announced locally and by the operators at the top; check on the morning rather than the week before. As of August 2026 there is no fixed seasonal closure, only weather-driven ones.
Documents. This is a real international border, so passports and stamps are required in both directions, and you need the vehicle registration document plus insurance valid for Lesotho. Lesotho appears on the commonly published lists of African countries where a Carnet de Passages en Douane is required for private vehicle entry — which puts it in a different category from South Africa, where one is not needed. Practice at small land borders and the paperwork actually demanded can differ from the published list, so confirm your specific case with a carnet-issuing motoring organisation and with Lesotho's revenue authority before you ride to the gate. Hired bikes are the other trap: most South African rental agreements need explicit written permission for cross-border travel and many exclude gravel roads outright.
Fuel and altitude. Fill at Underberg or Himeville. There is no fuel on the pass and Mokhotlong is a long way beyond the summit. At 2,876 m a naturally aspirated engine loses noticeable power, which is worth knowing before you meet a 1:3 hairpin on a loaded bike. Weather at the top is genuinely cold at any time of year, and the temperature difference between the bottom and the summit is large.
Gear notes for the escarpment
Tyre pressure is the first thing. Loose stone on a 1:3 gradient is exactly the situation where a few psi changes what the rear does under power, and the cold at the summit moves your pressures on its own — our guides to tyre pressure and to pressure loss in cold weather cover both halves of that, and a TPMS sensor means you see it happening instead of discovering it. The second is navigation: mobile coverage in the valley below the pass is unreliable and non-existent on much of the Lesotho plateau, so download the region for offline motorcycle navigation before you leave Underberg. If you are building a longer southern Africa trip, the South Africa overview covers how the pass fits with the Drakensberg and the coast, and a pre-ride check the morning of the climb is not optional on a road with no recovery service.
FAQ
Can you ride a motorcycle up Sani Pass?
Motorcycles do ride it, but South Africa's rule that only 4x4 vehicles are permitted onto the pass is applied at the bottom border post, and officials there decide what is suitable. Ask locally in Underberg or Himeville before committing, and expect more scrutiny on a loaded road bike than on a dual-sport.
Is Sani Pass tarred yet?
Partly. Phase one to the old Good Hope Trading Post finished in September 2012, and phase two up to the South African border post opened in October 2022. The final climb above that post — over 900 m of ascent in about 8 km — is still gravel, with no confirmed timeline.
What are the border post hours?
Both the South African and Lesotho posts open at 06:00 and close at 18:00. You cannot cross outside those hours in either direction, so plan the day around them.
Do I need a carnet for Lesotho?
Lesotho appears on the published lists of countries requiring a Carnet de Passages en Douane, unlike South Africa. What is actually demanded at a small border post can differ from the list, so confirm with a carnet-issuing motoring organisation and with Lesotho's customs authority before you go.
How steep is it really?
The average gradient over the whole climb is about 1:20, which sounds gentle, but that average includes a long, easy run through the foothills. The upper hairpins reach 1:3, and that is where the pass earns its reputation.
