The best acclimatization for the trek to Everest requires more time on the trek to Everest. Having enough annual leave or time off work can be challenging. Time is needed to acclimatize correctly so you can be safe and enjoy your Everest base camp trek and truly enough this amazing journey through the Himalaya’s. You need the best acclimatization schedule for Everest base camp. All the research over the past decade suggests more time is needed in the acclimatization process at 3,500m/ 11,500ft. That is why we spend 3 nights acclimatizing at this height on all our treks.

The trek to Everest base camp has so much to offer and should not be rushed for a number of reasons. A trek in Nepal and into the Everest region could change your life. You don’t want to rush this journey. You will want to take your time breath in this phenomenal place.

Everest base camp trek.

Acclimatizing high in the Everest region

The key is getting the acclimatization schedule correct. I have led over 50 expeditions to altitude over the last decade. I have climbed Everest and Kilimanjaro 18 times now. I have climbed Kilimanjaro in 5,6,7,8 days and there is a noticeable different in how I adapted and performed at altitude on a 5 day trip or an 8 day trip.

Likewise on the Everest base camp trek you need to have an acceptable acclimatization period on route to high altitude. Recent research suggests that you will need to adjust to the lack of oxygen at 3,500m/ 11,500ft. Adjusting and acclimatizing needs time. So the closest town at this height is Namche Bazaar 3,440m/ 11,286ft Our itinerary spends three night at this height.

Acclimatizing around Namche Bazaar

By spending three nights in Namche Bazaar, gives you the best chance to making a successful, safe and enjoyable experience high into the Himalaya’s. There will also be an additional two nights acclimatizing in Dingbouche 4,410m/ 14,468ft.  Which will set you up nicely for the journey above 4,900m/ 16,000ft and a dangerous lack of oxygen. Above 5,638m/ 18,500ft you would enter the base layer of the death zone. This means your body would slowly be dying above this height and can not fully adjust to the low levels of oxygen above this height.

Mt. Everest from Kala Phattar

The highest point on the Everest base camp trek is at Kala Phattar 5,545m/ 18,192ft. So you are getting really close to that extreme altitude level. With 50% less oxygen getting to your muscles, you have to make sure you acclimatize correctly in the early stage of the trek. If you acclimatize better lower down in Namche Bazaar, the better acclimatized you will be when you arrive above 5,000m/ 16,404ft. 

For two years we ran 50% of our treks with two days in Namche Bazaar. The other 50% of the treks ran with three nights in Namche. We set up a O2 test on each client over the space of a year. Our research suggested a big different between two and three night acclimatizing around the 3,500m mark. We saw an 85% increase in people stats. Suggesting that people who spent three nights in Namche bazaar 3,440m/ 11,286ft stood a far better chance of not getting altitude related sickness. This additional acclimatization is what helped people enjoy and get more from their Everest base camp experience.

After conduction our research on the ground in Nepal.  We added an additional night to all our Everest base camp treks in Namche Bazaar. We are getting the best results from our Everest base camp treks. We have a 99% success rate with clients enjoying their adventure, experience and journey into the mystical mountains of Nepal. We continue to do research on all our treks in Nepal, Kilimanjaro and all our trips. Making sure our results on high altitude treks are second to none.
