EVEREST ONE
AUSTRALIA'S ELITE SMALL-GROUP ADVENTURE GUIDES
Guiding Exceptional Journeys:
From Overnight Stays at Everest Base Camp to World-Class 8000m+ Ascents
Small Teams, Big Summits
Everest One was founded by Australian mountaineer and Everest summiteer Allan Cohrs, whose first climb in Nepal sparked a lifelong passion for the high places of the world. After a 24-year career in law enforcement, Allan followed his calling to the mountains and built Everest One into one of Australia’s leading small-group adventure companies.
​
From exclusive two-night stays at Everest Base Camp to world-class expeditions on 8000m peaks, we are proud to be the only Australian company guiding at the highest level. Allan has personally led more than 40 Himalayan expeditions, including successful ascents of Everest, Lhotse, Manaslu, and Cho Oyu, alongside numerous climbs on peaks such as Ama Dablam, Mera Peak, Kilimanjaro, and Aconcagua.
​
Our philosophy is simple: small teams create the biggest experiences. With expert guides, trusted Sherpa partners, and carefully crafted itineraries, we deliver adventures that are safe, personal, and unforgettable — journeys that go far beyond the summit.

WHERE OUR JOURNEY BEGAN
Born from a passion for the mountains, Everest One has grown into Australia’s leading
small-group adventure company, guiding climbers from base camp to the world’s highest peaks.
Everest One is the creation of Allan Cohrs BM, a professional mountain guide and Everest summiteer who first discovered his passion for the mountains over two decades ago on an introductory climb in Nepal. That first Himalayan adventure sparked a lifelong connection to the world’s highest places and set him on a path that would eventually shape Everest One into one of Australia’s leading adventure travel companies.
​
After that first climb, Allan immersed himself in the world of mountaineering and high-altitude trekking, building technical skills, resilience, and strength with each new expedition. He went on to climb many of the Himalaya’s most formidable peaks and in 2011, after a 24-year career in law enforcement, he made a life-changing decision: to trade his badge for boots and turn his passion into his purpose.
​
“That decision saved my life. I was heading down a dark road, but the mountains gave me a way out. Being in the wild, pushing through adversity, learning about myself with every step — that’s where I came alive again. The summit is always a bonus, but the journey is where the real transformation happens.”
​
Since then, Allan has guided expeditions and treks across the globe, from the Himalayas to the Andes, from Kilimanjaro to Tasmania’s wilderness, all under the Everest One banner. He has personally led over 40 expeditions in the Himalayas, including successful ascents of some of the world’s most iconic 8000m peaks: Mount Everest (8,850m), Lhotse (8,516m), Manaslu (8,163m), and Cho Oyu (8,200m). His climbing record also includes Baruntse (7,129m) and Ama Dablam (6,812m), along with multiple successful ascents of Mera Peak (6,476m), Lobuche East (6,119m), Island Peak (6,189m), Kilimanjaro, and Aconcagua (6,960m).
​
But Everest One is about more than climbing. Allan founded the company with the vision of creating world-class adventures for small groups, designed to deliver life-changing experiences in the highest mountains. Today, Everest One is the only Australian company guiding expeditions above 8000m and the only operator offering two-night stays at Everest Base Camp, sleeping on the Khumbu Glacier during the spring climbing season. Our signature Everest Base Camp trek is unlike any other, allowing trekkers to stay in handpicked Sherpa teahouses, join our Sherpa family in Phortse, and immerse themselves in the spirit of Himalayan expedition life.
​
Our Philosophy
​
“It is a big responsibility to take care of people in wilderness environments, whether for a few days or a few weeks. We take that responsibility seriously.”
​
From daily health monitoring and high-quality gear to nutritious meals, proven itineraries, and the support of world-class Sherpa guides, we go above and beyond to ensure every journey is safe, smooth, and successful. At the same time, we focus on making every adventure personal, fun, and meaningful. That is why so many of our climbers return year after year.
​
“There is no better feeling than seeing someone achieve what they once thought impossible, especially after months of preparation, self-doubt, and the courage to step beyond their comfort zone. These are the moments that stay with you forever. That is the true reason we do what we do.”

"I had already climbed Lobuche East and Ama Dablam with Allan from Everest One, but the dream was always bigger: to stand on an 8000m peak.
​
In 2023, that dream became reality when I joined the Everest One team on an expedition to Manaslu (8,163m), the 8th highest mountain in the world.
​
From the very beginning, Allan’s support was exceptional. He guided me through training with practical advice, even joining me on several 25km+ treks with serious elevation gain. He helped source specialist gear, stayed in regular contact, and made sure I was fully prepared before stepping foot in Nepal.
​
On the mountain, that same dedication shone through. Together with his Head Sherpa, Phunuru, Allan meticulously planned every stage of the climb. From reading the weather to choosing the perfect strategy, they set us up for success. At times, this meant pushing through the night to avoid the heat of the day, a tactic that proved invaluable at high altitude.
​
The Sherpa team Allan has built around Everest One are outstanding — highly professional, deeply experienced, and a joy to be with. Their positivity and camaraderie turned the tough days into unforgettable moments and made the entire expedition a true adventure.
​
The summit of Manaslu was the pinnacle of my 20-year climbing journey. At 65 years old, I was honoured to stand on the true summit as part of the first Australian team to achieve it, and proud to become the oldest Australian to do so.
​
The Himalayas are majestic, the people and culture are enchanting, and the experience with Everest One was life changing. If you want to push your limits with complete trust in your guides, there is no better choice than Allan and the Everest One team."

"My recent Kilimanjaro hike with Everest One and Allan Cohrs was truly the experience of a lifetime. I've always preferred booking with smaller, owner-operated companies because of the personal touch they offer as well as how the passion and effort that it takes to run a small business continuously shines through, and my trip with Everest One proved this was the right choice.
From the initial planning and prep stages to gear consultations, the trek, and all the random in-betweens, the service was top notch. It was a boutique experience where the details and the personal care was evident from the moment we touched down at the airport until our final drop-off.
What truly set this experience apart was Everest One’s individualized approach. The team’s thoughtfulness, genuine care, and compassion for every member of the crew was immediately noticeable. Also, Allan wasn't just a guide; he was a leader who ensured everyone felt supported, both mentally and physically. The guides and the entire support team were top-notch, and the operation was noticeably smooth and detail-oriented. High quality teams, starting hotel, gear, safety, and day to day operations… The seamless logistics allowed me to focus completely on the journey, knowing I was in the most capable hands.
The journey was rewarding, yet challenging, and pushed both mentally and physically. I went with some existing friends and came home having made new ones, all while experiencing a new culture and a part of the world.
I would absolutely recommend and book with Allan and Everest One again. In fact, my friend and I have already signed up to return to the Himalayas with Everest One to trek to Everest Base Camp and summit Lobuche East. Looking forward to another unforgettable adventure with Allan and the team!"

"When it comes to adventures, Mt Everest comes out on top on most people's lists. You imagine yourself standing on top of the world. The reality of how dangerous this is, the costs and commitment this requires, keeps this as an unrealistic fantasy to most.
This is how the idea popped into my head, I may not have the means to get to the top, but I wanted to go and get as close as I could.
While researching how to do this, I contacted Everest One and Allan. From the first contact Allan was a wealth of knowledge. Accessible via emails, messages, and calls. Every part of the trip had been carefully thought of, from your fitness preparation, equipment requirements, what to expect, who else will be joining, and who will be there to help. There was no stone unturned.
I am not the type to over plan any trip, and wanted to "experience", and "go with the flow". I had a false sense of how easy this was going to be, but luckily all the preparation had been done by Allan and his team to put me in a position to succeed.
There's so many variables that go into such trips and I can comfortably say if I did any other way or with anyone else, I never would have made it to the top of Lobuche East (6119m).
I cannot speak highly enough or recommend more of Everest One and Allan.
I have only fond memories from my trip, where the journey was just as good as the destination."
