5 Days Mount Kenya Trekking Safari (Sirimon-Chogoria Traverse)

A 5-day private Mount Kenya trekking safari via the Sirimon-Chogoria traverse with an extra acclimatisation day at Shipton's Camp (4,200m). The additional day at base camp significantly improves summit success rates by allowing the body more time to adapt to 4,200m before the Lenana push. Mountain guide, porter, and cook included. This is Katulu Africa Safaris' most recommended Lenana summit itinerary.

Trek at a Glance

Who Is This Trek For?

Ideal for: Trekkers who want the best achievable summit success rate on a private Lenana climb
Ideal for: Those who have never trekked above 4,000m before and want more body adjustment time
Ideal for: Anyone with even a mild prior history of altitude sickness who wants an extra acclimatisation buffer
Ideal for: Photographers who want more time in the high-altitude zone for landscape photography
Not ideal: those who are experienced high-altitude trekkers and prefer the faster 4-day profile
Not ideal: those with very limited time who cannot spare the fifth day

Why the Extra Day Matters

The difference between the 4-day and 5-day itinerary is a single acclimatisation day at Shipton's Camp (4,200m). On the 4-day, you sleep one night at 4,200m and attempt the summit the following morning. On the 5-day, you sleep two nights at 4,200m, with day 3 available for an acclimatisation hike to 4,500 to 4,600m and then descent back to Shipton's. This acclimatisation hike pattern, climbing high and sleeping low, is the proven method for improving the body's adjustment to reduced oxygen at altitude.

The physiological effect of an extra 24 hours at 4,200m is meaningful. Red blood cell production increases. Breathing patterns adjust. The summit push on a 5-day itinerary consistently produces better outcomes than the same push on a 4-day schedule, particularly for first-time high-altitude trekkers.

Katulu guide recommendation: The 5-day Sirimon-Chogoria traverse is the itinerary our guides recommend most consistently for first-time Lenana climbers. The extra day at Shipton's transforms the summit experience from a survival push into a strong, controlled climb where you have the physical reserves to enjoy the sunrise rather than just endure the ascent.

⚠  Altitude and health note: General guidance only. Not medical advice. Consult a travel medicine clinic before any high-altitude trek.
Acute Mountain Sickness (AMS) is a genuine risk above 3,000m. Symptoms include headache, nausea, fatigue, and dizziness. Never ascend further if symptoms are present.
‘Climb high, sleep low’ is the cardinal acclimatisation rule. Your guide enforces this on all Katulu Africa Safaris Mount Kenya treks.
Severe altitude illness (HACE or HAPE) is a medical emergency requiring immediate descent regardless of how close you are to the summit.
Diamox (Acetazolamide) is used by some trekkers for altitude sickness prevention. Consult your doctor about suitability before travel.
Travel insurance with high-altitude trekking cover and emergency evacuation is required as a condition of booking with us. A KWS mountain rescue fee applies and is included in our package price.
Certain medical conditions (heart disease, severe asthma, recent surgery) may contraindicate high-altitude trekking. Consult your doctor if uncertain.

Gear Checklist

Mount Kenya Gear Checklist
Tick off before departure. Hire equipment note: sleeping bags, trekking poles, and gaiters are available for hire in Nanyuki and through some operators. Confirm availability when booking.
□  Layering system: moisture-wicking base layer, insulating mid layer (fleece or down), waterproof outer shell (jacket and trousers)
□  Warm hat (balaclava recommended for summit treks; a warm beanie is sufficient for a day hike to 3,300m)
□  Insulated gloves and inner liner gloves
□  Trekking trousers (not cotton; quick-dry or softshell)
□  Thermal underwear base layer
□  3 to 4 pairs of moisture-wicking trekking socks
□  Well-worn trekking boots with ankle support and waterproof lining
□  Trekking poles (strongly recommended; reduces knee strain on descent and assists on steep terrain)
□  Headlamp with spare batteries (essential for forest entry at dawn; summit treks depart at 02:00 to 03:00)
□  Sunglasses with UV protection (strong equatorial UV above treeline)
□  Sunscreen SPF 50 and lip balm with SPF (extreme UV at altitude)
□  Water bottles or hydration bladder (minimum 2 litres capacity; drinking 3 to 4 litres per day is recommended at altitude)
□  Water purification tablets or filter (backup for mountain water sources)
□  High-energy snacks for the trail (energy bars, nuts, chocolate, dried fruit)
□  Personal first aid kit: blister plasters, pain relief, anti-diarrhoea tablets, antiseptic
□  Diamox (Acetazolamide) if prescribed by your doctor for altitude sickness prevention
□  Personal prescription medications with doctor's note if controlled
□  Sleeping bag rated to -10C minimum (camp temperatures below zero above 4,000m)
□  Small daypack (25 to 30 litres) for the trail
□  Waterproof pack cover or dry bags for electronics and documents
□  Camera with charged batteries (cold kills batteries fast; keep camera warm in your jacket)
□  Power bank
□  Passport and booking documentation
□  Travel insurance documents with emergency contact number
□  Cash (KES or USD) for crew tips and any personal purchases in Nanyuki or Chogoria town
□  Gaiters (recommended for Naro Moru Vertical Bog and scree on summit approach)

How to Book

Common Trekking Mistakes to Avoid

Mistake 1: Skipping the day 3 acclimatisation hike because you feel tired

Fix: The acclimatisation hike on day 3 is the most important preparation for summit day. Resting in the tent all day at 4,200m is less effective. Do the hike, return to Shipton's, rest well, eat, and sleep early.

Mistake 2: Setting a hard departure deadline for day 5

Fix: The Chogoria descent timing varies with summit day conditions and overnight camp. Avoid booking a tight Nairobi connection for day 5 afternoon. Build in buffer time in case the descent runs later than expected.

Mistake 3: Not telling the guide about prior altitude sickness history

Fix: If you have experienced altitude sickness before at 3,000m or above, tell your guide before day 1. This information shapes the guide's acclimatisation monitoring approach throughout the trek.

Mistake 4: Treating day 3 as a rest day and staying in the hut

Fix: The acclimatisation hike is part of the trek plan, not optional. Clients who rest fully at 4,200m on day 3 consistently show lower physical reserves on summit day than those who do the acclimatisation hike.
