Founded by Australian mountaineer and guide Allan Cohrs, and serviced by an expert team of world-class climbing guides, Everest One are a distinguished guiding company delivering high-altitude adventures, from climbing expeditions to the world's highest peaks to treks around the world.

Kick-start your next adventure

After a magnificent 2023, with incredible success in all of the climbs and treks run during the Spring and Autumn seasons in Nepal, including guiding the 1st Australian team to the true summit of Manaslu (8163m), with the youngest Australian and oldest climber in the world as part of our team, Everest One are excitedly waiting to kick-start 2024.

In fact, we saw 100% success during Autumn across all expeditions and treks, and an impressive 95% during Spring, as a result of careful planning and strategising, flexibility, committed clients, professional guides backed with a strong focus on safety, quality inclusions and extensive expertise in the high-altitude arena.

Everest One are the only Australian company involved in running expeditions above 8000m but also offer climbs of lower peaks including introductory climbs and treks.

With spectacular adventures scheduled throughout the year, including significant climbs of Mt Everest, Ama Dablam and Manaslu, and a number of treks to Everest Base Camp, we are also returning to Africa for our popular climb of Kilimanjaro, where we have already assisted more than 100 climbers in reaching the summit.

Whatever it is that drives or challenges you, makes you feel alive, or just reboots the system, there has never been a better time to dust off the boots and get out there.

What people are saying

Kilimanjaro climber with Everest One

Peter Sewell

Climbing Kilimanjaro was one of the proudest moments of my life. I had just turned 50 during the previous year, so to achieve a physical challenge like this was an amazing boost for my self confidence. 


As a public speaker, self confidence is your life blood. Confidence helps you to present your topic and build rapport with an audience.


Unfortunately, I had been hit by many personal challenges in a 5 year period, and in the process, there was a season where my confidence had reached rock bottom. I questioned my value as an individual and wondered what the future would look like. 


I’m happy to say now that I’ve never felt more empowered. I had the privilege of speaking at about 15 events directly after our climb and I have never enjoyed myself more. 


Thanks Everest One for leading me on a successful climb and giving me an adventure I will always remember.

Everest One client Colin Briggs on Manaslu in Nepal

Colin Briggs 

I have known Allan for over 30 years and I wouldn’t trust anyone else guide me and my family in the mountains.


Allan’s attention to detail, focus on safety and experience working at altitude are first class.


He knows exactly how to get the best out of his clients and when they need encouragement the most.


We would not have achieved successful summits of Kilimanjaro, Aconcagua and Lobuche East along with our trek to Everest Base Camp without him.


In 2023, I joined Allan and the Everest One team on another expedition, this time attempting my first 8000m climb of Manaslu in Nepal.

This was a serious undertaking and I was overwhelmed and so proud when, after many weeks of hard work and perseverance, I finally reached the true summit, becoming a member of the 1st Australian team to achieve this.


   I have so much faith and trust in Everest One and I wouldn't climb with anyone else.

Professor Jeff Dunn

Think about this.  The spectacle of the Himalayas, the anticipation of a physical challenge and the spice and colour of the Nepalese culture.  Final ingredient for the adventure of a lifetime?  Everest One!  The best in class.  Without a doubt - the best! 


Passionate about life, about making the most of opportunities and about recognising the potential in each and every person, they are terrific.  Skilled, professional and finely attuned to whatever goals a person might bring to the mountains. 


Having been a member of a number of expeditions including climbs of Lhotse (8516m), Lobuche, Mera Peak along with treks into Everest Base Camp, Everest One delivers “Adventure all the Way”! 


Do yourself a favour.
