ADVENTURE ALL THE WAY
Founded by Australian mountaineer, Mt Everest summiteer, 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.
Your Next Great Adventure Starts Here
After a spectacular 2023, Everest One proudly wrapped up an unforgettable year of high-altitude expeditions and treks in Nepal. From Spring to Autumn, our team achieved incredible success across all climbs, including a historic milestone: guiding the first Australian team to the true summit of Manaslu (8163m). That climb featured not only the youngest Australian to summit, but also the oldest climber in the world to reach the top — a true testament to what’s possible with the right mindset and expert support.
​
Fast forward to the April–May 2024 Himalayan climbing season, and Everest One continued its momentum with successful ascents of Mount Everest, two Lobuche East summits, and two Everest Base Camp treks — all executed with precision, passion, and an unwavering focus on safety.
​
This year, after guiding treks and climbs in Nepal during the Spring season, we returned to Tanzania, guiding a fantastic team of 15 climbers from across the globe to the summit of Kilimanjaro, the highest point in Africa. It was a powerful reminder of what determination, teamwork, and expert guidance can achieve at altitude.
​
Now, as we shift focus to the Autumn climbing season in Nepal, we’re gearing up for an epic line-up of adventures, including ascents of Mera Peak and Ama Dablam, another exciting Lobuche East climb, and our signature Everest Base Camp trek.
​
Looking ahead, the 2026 expedition calendar is already taking shape and it's set to be our most ambitious year yet with another Everest expedition along with an amazing selection of climbs and treks in Nepal, Africa and South America
​

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.

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.

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”!
