Mount Kenya Climbing Guide: Routes, Altitude and Preparation

Mountain Adventures · By the Bush Camp Tours safari team, Nairobi · Updated 2 October 2026

Most trekkers on Mount Kenya aim for Point Lenana (4,985m), which can be reached on foot without ropes or climbing skills. The mountain's true summits, Batian (5,199m) and Nelion (5,188m), are technical rock climbs for experienced mountaineers.

A Lenana trek takes four to six days, depending on the route. The main challenge is altitude: you gain height quickly, so pacing and acclimatisation matter more than raw fitness.

Choosing a route

  • Sirimon (north-west): drier and more gradual, with good acclimatisation and the Mackinder Valley's giant lobelias and groundsels. Our 4-day Sirimon trek uses this route.
  • Chogoria (east): often called the most scenic, passing lakes and the deep Gorges Valley. Longer access road.
  • Naro Moru (west): the most direct, with a steep, often boggy section known as the "vertical bog". Less time to acclimatise.

Many trekkers go up one route and down another - Sirimon up and Chogoria down is a popular combination that adds a day and a lot of variety.

A typical 4-day Sirimon itinerary

  • Day 1: drive from Nairobi to Sirimon Gate (2,650m), walk to Old Moses Camp (3,300m).
  • Day 2: across the moorland to Shipton's Camp (4,200m).
  • Day 3: pre-dawn start for Point Lenana at sunrise, then descend.
  • Day 4: descend to the gate and drive back to Nairobi.

Adding a day - either an acclimatisation day or a descent via Chogoria - makes the trek more comfortable.

Altitude and your body

You climb above 4,000m within two days, which is faster than on many Kilimanjaro routes. Mild headaches and breathlessness are common. Warning signs such as severe headache, confusion, vomiting or loss of coordination mean you must tell your guide and descend.

  • Walk slowly, even when you feel strong
  • Drink plenty of water
  • Ask your doctor about altitude medication before you travel
  • Accept your guide's decision on summit morning

Fitness

You should be able to walk for several hours a day on consecutive days over uneven ground. Hill walking with a daypack in the weeks before your trip is the best preparation.

What to pack

  • Warm layers, including a down jacket, hat and gloves - nights near the top drop below freezing
  • Waterproof jacket and trousers
  • Broken-in waterproof boots
  • A sleeping bag rated well below freezing (available to hire locally)
  • Headtorch, sunglasses and sunscreen
  • Trekking poles

Bulky items can usually be hired before the trek.

Best time to climb

The driest periods are roughly mid-January to the end of February and July to October. The mountain can be climbed at other times, but expect more rain, mud and cloud. Weather at altitude can change quickly in any month.

Practicalities

  • A licensed guide is required; porters carry the main loads.
  • Park entry and hut or camping fees apply and are included in our trek price.
  • Nanyuki is the usual base for Sirimon and Naro Moru.
  • Make sure your travel insurance covers trekking to 5,000m.

The bottom line

Choose Sirimon for a well-paced first trek, add a day if you can, walk slowly and listen to your guide. Mount Kenya is quieter than Kilimanjaro and rewards those who prepare. If you are considering both, read our Kilimanjaro trekking guide.

Quick Answers

How hard is it to climb Mount Kenya?

Point Lenana is a demanding trek, mainly because of the altitude. It does not need technical skills.

Is Mount Kenya harder than Kilimanjaro?

Lenana is lower than Uhuru Peak, but the standard itineraries gain height faster. Many people find the two comparable.

How many days should I allow?

Four days minimum on Sirimon; five or six for a traverse or extra acclimatisation.
