With its towering height of 5,895 metres (19,340 ft), Mount Kilimanjaro stands as Africa’s highest peak and the world’s tallest free-standing mountain. But just how hard is it to climb Kilimanjaro?

In this guide, we’ll break down everything you need to know about the difficulty of hiking Kilimanjaro — from altitude and weather to routes and physical preparation. One thing is certain: while the trek isn’t easy, the reward is absolutely worth it.

Is Climbing Kilimanjaro Difficult?

In short — yes, but not in the way you might expect. Kilimanjaro doesn’t require technical climbing skills, and most of its trails are straightforward hikes. However, what makes the climb truly challenging is the altitude.

As you ascend, oxygen levels drop significantly — only about 50% of sea level oxygen is available at the summit. This can cause altitude sickness, with symptoms like nausea, dizziness, and shortness of breath.

Add to that the freezing nighttime temperatures, basic sleeping conditions, and days of trekking, and it becomes clear why many consider it a tough experience.

The Main Challenge: Altitude

Altitude is the single most difficult aspect of hiking Kilimanjaro. At the summit, the oxygen level is around 49% of what’s available at sea level, making it physically draining even for the fittest hikers.

Altitude sickness can hit anyone, regardless of fitness level. That’s why acclimatization is crucial. Opting for a longer route (6–9 days) allows your body more time to adjust and increases your chances of success.

Popular Routes and How Long They Take

There are eight primary routes up Kilimanjaro, each varying in distance, duration, and difficulty:

Longer routes like Lemosho, Rongai, and the Northern Circuit offer better acclimatization and have higher success rates (up to 95%).

Shorter treks might be cheaper but usually have lower success rates — as low as 60%. The Western Breach is the most dangerous route due to rockfall risk and steep sections, while Lemosho is considered the most beginner-friendly and scenic.

Marangu, also known as the “Coca-Cola route,” is unique for offering huts instead of tents but is often crowded.

Camping and Accommodations

On most routes, you’ll be sleeping in tents. Marangu is the only route with huts. Conditions are basic — no showers and limited amenities — but clean toilets are available along the way.

Sleeping in a tent for 5–9 days can be a challenge for those unfamiliar with camping. Still, most hikers adjust quickly, especially when part of a supportive group.

Weather on Kilimanjaro

Despite being in Africa, Kilimanjaro’s summit can be bitterly cold. Temperatures at night can plunge to -20°C (-4°F).

The best times to climb are during the dry seasons: July–October and December–February. While weather is generally stable during these months, sudden changes can still occur due to the altitude.

Proper layering, insulated sleeping bags, and quality gear make a huge difference.

Do You Need to Be Super Fit?

You don’t need to be an elite athlete, but you do need good physical and mental endurance. Hikes last several days, and summit day alone can involve up to 15 hours of walking in thin air and cold temperatures.

A solid training plan that builds stamina and leg strength, combined with mental preparation, can go a long way.

Being mentally ready — knowing it won’t be easy, being okay with discomfort, and staying motivated — is just as important as physical fitness.

How Hard Is Kilimanjaro? Success Rates Explained

Success rates vary by route:

• Lemosho Route: ~90%

• Northern Circuit: ~95%

• Marangu Route: ~65%

On average, about 65% of all climbers make it to the summit. The biggest factors affecting success are acclimatization time, altitude adjustment, and individual fitness.

Can the Average Person Climb Kilimanjaro?

Absolutely. Many people with no prior trekking experience have successfully reached the summit. Key to success includes:

• Good physical preparation

• Choosing the right route

• Being mentally prepared

• Having experienced support
