Western Breach – The Most Challenging Route to the Roof of Africa

Mark Whitman

The Western Breach on Mt Kilimanjaro is the most technically challenging route to summit.

As the name suggests, the Western Breach sits on the western side of Kibo and is a gap to the summit that was formed hundreds of thousands of years ago by volcanic eruptions and lava flows from Kibo’s Crater (read: how Kilimanjaro was formed).

Due to its steep and rocky slopes, the Western Breach is considered  risky and is known as the most dangerous Kilimanjaro route. Many operators don't run it as it's not really a suitable choice for the average trekker. It is however, the fastest route up Mt Kilimanjaro and is therefore quite popular with experienced mountaineers.

Here's our complete guide to Kilimanjaro's Western Breach.

Western Breach Kilimanjaro Route Map

The Western Breach can be approached from many of Kilimanjaro’s routes, including the Lemosho and Shira Route in the West, and the Machame and Umbwe Route in the South.

The Umbwe Route is the most popular and demanding approach, as it is the fastest and most direct route up Mt Kilimanjaro. 


Western Breach Itinerary

The Western Breach approach usually starts from Umbwe Gate at 1,600 meters and rapidly ascends to Barranco Camp at 3,900 meters, via Umbwe Camp (2,850 meters).

From here most trekkers would usually take the Southern Circuit to Karanga and then onto Barafu base camp to approach Kilimanjaro’s summit from the South East.

Instead, the Western Breach route continues north up to Lava Tower for the night and then onto Arrow’s Glacier to join the Western Breach approach (see Western Breach map above).

The fourth day is a steep scramble up to the Reutsch Crater (5,800 meters) where trekkers spend the night near one of Kilimanjaro’s last remaining glaciers, Furtwangler Glacier. This option, of spending a night at Crater Camp, makes the Western Breach quite appealing for experienced hikers and climbers.

Depending on route variation chosen, the Western Breach has quite a lot of exposure (Yosemite Decimal System Class 3 with some sections of Class 4). Learn more about these classes here.

Day five is a short trek from the Reutsch Crater to the summit of Kilimanjaro, Uhuru Peak (5,895 meters). Trekkers typically return down the southern slopes of Kibo to Barafu Camp (4,680 meters) and then onto Mweka Camp (3,100 meters) for their last night on Kilimanjaro.

We recommend spending an additional night at Lava Tower to aid the acclimatisation process and reduce the risk of altitude sickness.

The route is usually completed in six days and does not provide much time for trekkers to acclimatise. For this reason, the Western Breach should only be considered by trekkers with high altitude trekking experience.

In 2015, the Western Breach wall was used as the launch pad for Valery Rozov's successful Kilimanjaro base jump.

Kilimanjaro Western Breach FAQ

Is the Western Breach dangerous?

Yes, relative to the other routes up Mt Kilimanjaro, the Western Breach is the most dangerous option. It has sections of high exposure and steepness. You need to be comfortable with exposure, basic rope use, and rock scrambling. In high winds the route is susceptible to rock falls, which can and have resulted in hiker deaths. 

Do I need technical climbing skills for the Western Breach on Kilimanjaro?

You don't need technical climbing skills, but if you've never done high exposure hiking with a fixed rope, then I would caution against doing the Western Breach.

How long and how many days is the Western Breach route?

At 52km, the Western Breach is the shortest Kilimanjaro route. It is usually trekked in 6 days.

What equipment do I need for the Western Breach?

Technical equipment on the Western Breach includes a climbing helmet, ice axe to cut steps and provide support in snowy conditions, and a fixed rope with carabiners. All this equipment is generally provided by your tour operator.

What accidents have happened on the Western Breach?

In 2006 a tragic accident occurred when a rockfall killed three trekkers on the route. Mount Kilimanjaro authorities closed the route briefly but it re-opened in late 2007.

In 2015, internet entrepreneur Scott Dinsmore was killed by a falling rock near Arrow Glacier.

Due to its high risk profile most tour operators do not offer treks using the Western Breach to the summit.

  1. I really like the competive and daredevil way! How do I prepare for altitude change and when is the best time to start this hike?

  2. Hi mark,
    I am expecting to climb Kilimanjaro by the western breach in January spending 2 nights in the crater. We are planning on climbing the western breach via the lemosho route for better acclimatization, any thoughts? Also should I bring my high altitude boots (scarpa phantom 6000) or will my normal boots – scarpa cumbre suffice.

    1. Hi Sunil, great to hear that you are taking on the Western Breach. The Lemosho route is indeed one of the best approaches for acclimatisation, and undoubtedly the best route in if you plan to do the Western Breach. In terms of boots I would say the Phantom 6000 are overkill and the Cumbre should be perfect if you need to use crampons. For the hiking sections, which cover almost the whole route, you will only need normal mid-weight hiking boots. Hope this helps!

  3. can you contact us re professional and semi professional climb for Kilimanjaro. We are looking ti take a team. Thanks…Adrian

  4. I summited by way of Umbwe to western breach in 2008. It was a virtually untouched face. Mostly sketchy scramble. As we climbed we sent hundreds to thousands of pounds of rocks down beneath us. I think this is another reason the route is discouraged. Because multiple groups would end in tragedy. We summited in 27 hours and down climbed all the way to the base with an Older Guide , named Simon. He claimed the WB was his office. He was a legend
