Driving Mpumalanga's Mountain Passes

There's a reason people from all over South Africa — and the world — make the pilgrimage to Mpumalanga's Escarpment. The views are staggering, the roads are dramatic, and the journey itself is half the adventure. But those same breathtaking passes that make the Panorama Route so iconic can also catch an unprepared driver completely off guard. Whether you're a Lowveld local who tackles these roads every week or a visitor dropping down from the Highveld for the first time, knowing how to handle Mpumalanga's mountain passes makes every trip safer, smoother, and far more enjoyable.

Know the Passes Before You Drive Them

Mpumalanga is home to some of the most dramatic mountain roads in southern Africa. The main passes you're likely to encounter include:

Long Tom Pass (R37) — Running between Sabie and Lydenburg (Mashishing), this is one of the highest passes in the country and is named after a Boer War cannon. It's long, winding, and often shrouded in mist.
Montagu Pass / Hendriksdal descent — The stretch of road between Nelspruit (Mbombela) and Sabie via the R37 drops and climbs through spectacular indigenous forest.
The Kowyn's Pass (R533) — Between Hazyview and Graskop, this pass twists through lush forest and is popular with tourists heading to the Blyde River Canyon area.
Abel Erasmus Pass (R36) — Connecting Hoedspruit to Ohrigstad and the Escarpment, this pass is steep, narrow in places, and shared with heavy vehicles.
De Kaap Valley roads — Around Barberton, the winding roads through the hills are equally demanding and less frequently mentioned.

Spend five minutes with a map before you set off. Understanding the elevation changes, the length of a descent, and whether the road is shared with trucks will help you plan rest stops and manage your vehicle better.

Check Your Vehicle Before You Head Up — or Down

This is non-negotiable. Mountain passes put enormous strain on brakes, tyres, and engine cooling systems. A car that seems perfectly fine around town can reveal its weaknesses very quickly on a 15-kilometre descent.

Before any pass, check the following:

Brakes: Listen for any grinding, squealing, or a soft pedal feel. If your brakes feel spongy or you're overdue for a service, get it sorted before you drive Long Tom Pass with a full load of passengers.
Tyres: Check tread depth and tyre pressure. Under-inflated tyres overheat on long descents; over-inflated tyres lose grip on sharp corners.
Coolant and engine temperature: On steep climbs, especially in summer, engines work harder. Keep an eye on your temperature gauge and pull over safely if the needle creeps into the red.
Transmission (especially automatics): Automatic gearboxes can overheat on long descents if you ride the brakes excessively instead of using engine braking. Most modern automatics have a manual mode or low gear selector — use it.
Lights: Mist on Long Tom and Kowyn's Pass can reduce visibility dramatically. Make sure your lights — including fog lights if fitted — are working.

Use Engine Braking — Your Brakes Will Thank You

One of the most common mistakes drivers make on mountain descents is riding the brake pedal all the way down. This overheats your brake pads and discs, reduces braking effectiveness, and in extreme cases can cause brake fade — where your brakes stop responding properly. It's as frightening as it sounds.

Instead, select a lower gear before you start the descent:

In a manual vehicle, drop to third or second gear depending on the gradient. Let the engine hold the car back while you use brakes in short, controlled applications.
In an automatic, use the manual or sport mode to select a lower gear, or use the "L" or "2" setting on older automatics. On the descent of Abel Erasmus Pass, for instance, this makes an enormous difference.
Never coast in neutral on a descent. You lose engine braking entirely and you're relying solely on your brakes.

A good rule of thumb: if you would drive up a hill in a certain gear, drive down in the same gear.

Dealing with Mist, Rain, and Wet Roads

Mpumalanga's Escarpment is one of the wettest regions in South Africa. The area around Sabie, Graskop, and Pilgrim's Rest receives substantial summer rainfall, and mist can roll in at almost any time of year, particularly in the early morning and late afternoon.

Tips for wet and missy conditions:

Slow down significantly. Wet tar on a mountain pass with leaf debris and steep camber is genuinely treacherous.
Increase following distance. You need far more space to stop safely on a wet descent.
Use low-beam headlights in mist — high beams reflect off the mist and reduce visibility further.
Watch for baboons and wildlife on roads around the Blyde River Canyon and near the Kruger National Park boundary. Animals don't move for approaching cars and can appear suddenly.
Be particularly careful on the first rains of summer. Months of built-up oil and dust on dry tar create a slick surface until the road has been thoroughly washed.

Plan Your Route and Timing

The Panorama Route — taking in God's Window, Bourke's Luck Potholes, the Blyde River Canyon viewpoints, and the towns of Graskop and Pilgrim's Rest — is best driven when you have time on your side. Trying to rush it leads to poor decisions on the road.

A few practical route suggestions:

From White River or Hazyview: Head up Kowyn's Pass on the R533 to Graskop in the morning when the light is best for photos and mist has often cleared. Spend the day on the Panorama Route and return before late afternoon.
Sabie to Lydenburg via Long Tom Pass: Allow at least an hour just for the pass itself. There are several safe lay-bys with views where you can stop and let your brakes cool if needed. Don't skip them.
Hoedspruit to Tzaneen via Abel Erasmus and the Strijdom Tunnel: This is a spectacular drive but involves sharing the road with heavy trucks. Keep left, be patient, and never overtake on a blind rise.
Barberton to Nelspruit: The R38 winds through beautiful hills and is far less congested than the N4. Ideal for a scenic Sunday drive, but respect the sharp bends.

Always let someone know your intended route if you're heading into more remote areas, and carry water, a basic emergency kit, and a charged phone.

Overtaking, Patience, and Sharing the Road

On a mountain pass, impatience is dangerous. There will be slow-moving trucks, nervous tourist drivers in hire cars, motorcyclists enjoying the twisties, and cyclists on the more popular routes.

Only overtake where it is clearly safe and legal. Solid white lines on mountain passes are there for good reason.
If you're holding up traffic, use a safe lay-by or pull-off to let faster vehicles past. It's courteous and reduces frustration for everyone.
Give motorcyclists space. They are particularly vulnerable on mountain roads and may be taking different lines through corners than you expect.
Watch your speed through the towns of Graskop, Sabie, and Pilgrim's Rest. These are busy tourist towns with pedestrians and erratic stop-and-go traffic.

Is Your Car Up to the Challenge?

Not every vehicle handles mountain passes equally well. Older vehicles with worn brakes, dodgy tyres, or temperamental cooling systems can turn a scenic drive into a stressful ordeal. If your current car gives you cause for concern every time you head up to the Escarpment, it might be time to consider something more reliable.

At Everest Motoring in White River, we stock a carefully selected range of pre-owned vehicles suited to Mpumalanga's diverse terrain — from practical family SUVs that handle the passes with ease, to fuel-efficient sedans perfect for the daily run between White River, Nelspruit, and Hazyview. Our team knows these roads personally, and we're happy to advise you on the best vehicle for your lifestyle and the routes you drive regularly.

Browse our inventory and find a vehicle that's as ready for the Panorama Route as you are. Because the mountains aren't going anywhere — and neither should your confidence behind the wheel.
