Everest One leads small-team expeditions to Everest, Manaslu, Kilimanjaro, Everest Base Camp and beyond – with expert Sherpa support and proven success.
Achievements That Inspire
​
2023 was a year of milestones for Everest One. From Spring through Autumn in Nepal, our teams reached incredible heights, including guiding the first Australian team to the true summit of Manaslu (8163m). That expedition was history-making, with the youngest Australian and the oldest climber in the world standing together on the summit — proof that with the right mindset and expert support, anything is possible.
​
Momentum Into 2024
​
The April–May Himalayan season saw continued success with summits of Mount Everest, Lobuche East climbs, and Everest Base Camp treks, all carried out with precision, passion and safety at the core. Soon after, we returned to Africa where a strong international team of 15 climbers stood on the summit of Kilimanjaro (5895m) — a celebration of determination, teamwork and expert guidance.
​
What’s Next?
​
As we move through the 2025 and 2026 climbing seasons, our expedition calendar is bigger than ever. On the horizon are adventures to Mera Peak, Ama Dablam, Lobuche East, Everest Base Camp, and of course, another ascent of Mt Everest itself. Looking further ahead, we’re returning into South America and Africa, offering climbers even more life-changing journeys.

" I had the privilege of climbing Mount Everest under the leadership of Allan Cohrs. As expedition leader and manager of the Everest One team, Allan handled every aspect of the climb with precision and care, from logistics and safety to weather analysis and summit strategy.
​
His judgement proved invaluable when he identified a unique weather window that very few others took advantage of. This allowed me the extraordinary experience of spending forty minutes on the summit of Everest with only my Sherpa – an opportunity made possible by Allan’s expertise and foresight.
​
Allan has the rare ability to be both a trusted friend and a consummate professional. His calm presence, vast network of connections throughout Nepal and the Khumbu region, and deep knowledge of the mountains ensured the climb was smooth, safe, and exceptionally well-managed from start to finish.
​
Beyond his skill and organization, Allan’s companionship made the journey as rewarding as the summit itself. I recommend him without hesitation to anyone seeking leadership, reliability, and experience at the highest level of mountaineering."​

"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."

"Our Everest Base Camp and Lobuche East expedition with Everest One was truly the experience of a lifetime. We were introduced to Allan and Everest One through family recommendations, and from the outset we knew we were in the best hands. What sets Everest One apart is their Australian base, their unwavering commitment to safety, and their assurance that all regulations are met.
The organisation before even arriving in Kathmandu was outstanding. From airport pickup, to staying at the comfortable hotel, ensuring all our gear was correct, every detail was handled seamlessly. Along the trek to Everest Base Camp, the tea houses were clean and welcoming, and being able to spend two nights at Base Camp itself was a highlight. Standing on the Khumbu Icefall at the start of the Everest ascent was a surreal and unforgettable moment.
Climbing Lobuche East with our lead guide, Phunuru Sherpa was the most incredible experience of our lives. His expertise, motivation, and support were truly game changing and directly led to our successful summit. Both Phunuru and Kanchi took such amazing care of us throughout the trek, making sure meals were prepared quickly, hot water bottles were waiting at night and guiding us safely along every trail.
Allan is an absolute professional - personable, knowledgeable, and fun to be around. He made the entire journey not only safe but also enjoyable, and we always felt supported.
We cannot recommend Everest One highly enough. It is the only company we would ever trust with our lives on such an extraordinary adventure. We will absolutely be booking with Everest One again."
