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 significantly improves summit success rates. Mountain guide, porter, and cook included. Budget and mid-range options available. This is the itinerary we recommend most often to first-time Mount Kenya climbers.

Quick Highlights

Who Is This Trek For?
Ideal for: First-time high-altitude trekkers who want the best achievable summit odds for their fitness level
Ideal for: Those with any prior altitude sickness history who want an extra acclimatisation buffer
Ideal for: Budget trekkers who want maximum summit success chance without the cost of a 6-day itinerary
Ideal for: Anyone who prioritises arrival at the summit in good shape over speed
Not ideal: experienced high-altitude trekkers who prefer the faster 4-day profile
Not ideal: those with very limited time who cannot spare the fifth day

One Extra Day, One Big Difference

The honest case for the 5-day over the 4-day is simple: one extra day at Shipton’s Camp (4,200m) gives your body more time to adapt before the summit push. On the 4-day, you sleep once at 4,200m and attempt Lenana the next morning. On the 5-day, you sleep twice at 4,200m, with an acclimatisation hike to 4,500 to 4,600m between those two nights. That acclimatisation hike, climbing higher than where you sleep and then returning, is the proven method for improving altitude adaptation.

The difference in summit success rate between a single night at Shipton’s and two nights with an acclimatisation hike is meaningful for most first-time high-altitude trekkers. This is the itinerary our guides recommend most often. Not because it is longer, but because the summit experience it produces is a strong, controlled climb rather than a survival push.

Budget transparency: The 5-day costs more than the 4-day because it includes an extra day of park fees (USD 80 per adult), an extra porter and cook day, and an extra night at Shipton’s Camp. There is no accommodation upgrade between the 4-day and 5-day; the huts are the same. The cost difference is purely the extra mountain day.

Tipping guide (per trek, paid at end in cash): Mountain guide: USD 15 to 20 per day
Porters: USD 8 to 12 per day each
Cook: USD 10 to 15 per day
Tips are important to crew livelihoods and are appreciated. Your guide can advise on current KES equivalent amounts.

⚠  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. Headache, nausea, fatigue, and dizziness are the warning signs. Never ascend further when symptoms are present.
‘Climb high, sleep low’ is the cardinal acclimatisation rule. Your guide applies this on all Bienvenido Mount Kenya treks.
Severe altitude illness (HACE or HAPE) is a medical emergency. The only treatment is immediate descent.
Diamox (Acetazolamide) is used by some trekkers for altitude sickness prevention. Ask your doctor 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 may contraindicate high-altitude trekking. Consult your doctor if you have heart disease, severe asthma, or have had recent surgery.

Frequently Asked Questions

What does the acclimatisation hike on day 3 actually do?

The acclimatisation hike from Shipton’s (4,200m) to approximately 4,500 to 4,600m and back is an application of the climb-high-sleep-low principle. By going higher than where you sleep, your body gets a controlled exposure to reduced oxygen at 4,500m, then recovers at 4,200m overnight. Red blood cell production accelerates and breathing patterns adjust. The result is a body that is better prepared for 4,985m the following morning than one that simply rested at 4,200m all day.

Is the 5-day always better than the 4-day?

For most first-time high-altitude trekkers, yes. For experienced trekkers who have been above 4,500m before without AMS issues, the 4-day is a perfectly reasonable choice. If you have trekked Kilimanjaro, done the Everest Base Camp trek, or have been at 4,000m or above without difficulty, the 4-day is fine. If this is your first time above 3,000m or you have had AMS before, the 5-day is the better choice.

Does the 5-day cost significantly more than the 4-day?

The cost difference is one additional day of KWS park fees (USD 80 per adult), one extra crew day, and one extra night at Shipton’s Camp (hut fee). There is no accommodation upgrade between the two itineraries. Contact us for a side-by-side quote on both if budget is a deciding factor.

How to Book

Common Trekking Mistakes to Avoid

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

Fix: Feeling fine at Shipton’s on day 3 morning is exactly why you should do the acclimatisation hike. It prepares you for feeling fine at 4,985m on day 4. Lying in the tent all day is less effective than the hike.

Mistake 2: Booking a tight day 5 Nairobi connection

Fix: The Chogoria descent and drive to Nairobi takes most of the day 5. Avoid tight afternoon or evening Nairobi commitments on day 5.

Mistake 3: Not disclosing prior altitude sickness history at booking

Fix: Prior AMS history shapes the guide’s monitoring approach throughout the trek. Disclose it at booking, not on the mountain.

Mistake 4: Treating day 3 as a rest day

Fix: The acclimatisation hike is part of the trek plan. It is not optional. Clients who rest at 4,200m instead of doing the hike consistently show lower physical reserves on summit day.
