The Tlaeeng Pass has a fairly minor altitude gain of 140m and only one hairpin chicane section. Other than those, the pass is easy enough to traverse, but what makes this pass stand out from the rest is it's maximum altitude of 3262m which makes it the 2nd highest pass in Lesotho. This road is also known as the Oxbow-Mapholaneng Road.
Together with the Moteng, Mahlasela and Khalo La Lithunya Passes, it forms a quartet of altitude gaining passes on the A1 route between Butha Buthe and Mokhotlong. The main point of interest occurs at the southern end of the pass which is the Letseng Diamond Mine.
This is an extremely high altitude pass. It's lowest point is higher than the highest pass in South Africa. You will start at 3012m ASL and climb streadily to summit at 3246m ASL. Despite the extreme altitudes, the pass itself only contains 16 bends corners and curves and only two have an arc greater than 90 degrees.
Assuming fine weather, the pass should present no problems other than a lack of power in your vehicle due to the oxygen starved air and the very real possibility of experiencing headaches and nose bleeds. Many visitors to Lesotho experience altitude sickness and especially those that have travelled up from the coast. If you normally suffer from AS, please vsit your pharmacist for advice before setting off on your journey.
In the colder months, this pass will have snow and ice on it. If you're not in a 4WD vehicle it's best to choose an alternative route or wait a day or two for conditions to improve. Snow is less of a problem than ice. Ice creates extremely dangerous conditions on tar (much worse than gravel) which can quickly cause a total loss of control.
The pass connects Mokhotlong in the east with the northern villages, as well as the Afriski Resort via the main route - the A1.
This major pass is located between the town of Kala in the west and the Afriski Resort in the north in the northern quartile of Lesotho. It has a huge altitude gain of 896m that stretches over a distance of 15.3 km which converts into an average gradient of 1:17, but don't be fooled by that figure as it includes the descent. Most of the ascent from the western approach is between 1:5 and 1:8.
The 91 bends, corners and curves will require your full concentration. Amongst those there are 4 extreme hairpin bends and one full horseshoe. The A1 road is the major route across the northern sector of Lesotho and as such carries a fair volume of traffic including some very large trucks. These need the full width of the road to negotiate the hairpin bends, so be fully aware of this as you proceed along this pass.
The pass has been the scene of numerous accidents, mostly involving trucks and buses. All the passes in Lesotho are above the snow line, so driving here in winter invariably means having to deal with snow and ice, which is to be avoided if possible - and especially so if you are not in a 4WD vehicle.

Passes are classified according to provinces and feature a text description, Fact File including GPS data, a fully interactive dual-view map and a narrated YouTube video.
We are as passionate about maps as we are about mountain passes. A good map is a thing of beauty that can transport you into the mists of time or get your sense of adventure churning. It is a place to make discoveries about deserts and seas, mountains and lakes; of roads leading into places you have not been before; a place to pore over holiday destinations or weekend camping trips. A map is your window to the world.
