A note from our CEO

Our Mission

"I believe in the transformative power of adventures, the opportunities for personal growth inherent in challenge, am moved by the beauty in the natural world and love to see people push beyond the norms of their everyday lives. 

Adventures are powerful vehicles for self discovery, intoxicating in their nature and spiritual in their intensity. 

Through their lens I have discovered myself fascinated by different cultures, happiest in wild places and feeling most alive surrounded by and in the depths of challenge, its unique camaraderie, excitement and focus.

In my career as an adventurer, I have found most precious the feeling of striving for something, somewhere different, somewhere indescribable in beauty or truly awesome to behold.

And I have experienced the joy, energy and fulfilment remain with me long after I return home and in that period have felt unstoppable. 

The great Kazakh mountaineer, Anatoli Boukreev said it best; "Mountains are not stadiums where I satisfy my ambition to achieve; they are the cathedrals where I practice my religion. I go to them as humans go to worship. On every journey I am reborn."

And so here we are, the custodians of a unique spirit, ready and wishing to share with you these incredible challenges we have crafted for you in some of the biggest and most beautiful environments in the world; safely, with incredible teams, guides and in the best style imaginable. 

Our hope is for you to experience and draw from these same feelings that led me to create this business and follow this dream. May the adventures be life-changing for you. 

Lets go up."

Our Story

The case of the ‘true summit’ is an oft and increasingly held debate in mountaineering, most famously perhaps, in the case of Manaslu, the eighth-highest mountain in the world. 

People had long climbed to the commercial or fore-summit, but not the 'true summit'; only a meter or so higher than the commercial summit, but accessed along a narrow ridge. 

Many of the people who claimed a summit of Manaslu as one of the cherished '14 peaks' (the 14 mountains above 8000m) had in fact only been to the commercial summit. 

When the true summit became clearly identified in recent years the most dedicated among them committed to re-climbing Manaslu to reach the true summit and take their rightful place among the adventuring elite.

The ‘true summit’ is more than just a question of what constitutes reaching the top of a great mountain. 

The ‘true summit’ is not just the top, it is your best effort and your best self; a profound experience and feeling.




Our Team

The True Summit team is a collective of professional adventurers, alpinists, highly regarded professional guides, expedition leaders, fearless endurance athletes or a combinations of all these things. 

Each person is unique, but everyone shares a love, passion and enthusiasm for adventure, nature, self-discovery, and the outdoors; mountains in particular.

The character traits we seek in the people who work with us are mastery, courage, determination, empathy, the ability to think under pressure and an uncompromisable commitment to safety, best practices and continually trying to improve. 

Above all things, they must be a joy to be around.

Oliver is a qualified Mountain Leader and the Founder of True Summit Adventures. He grew up in a small village in rural Hampshire, UK and started traveling extensively from his late teens, solo traveling through Mozambique in the aftermath of the civil war and flooding there when he was 18.

Oliver has competed in many marathons, duathlons and climbed many mountains of 4, 5 and 6000m including European Classics, Mont Blanc and Grand Paradiso, Andean Classics, Vallunaraju, Cotopaxi, Antisana and Chimborazo, Toubkal and Kilimanjaro in Africa, Lobuche East and Mera Peak in Nepal as well as touching Camp 3 on Mount Everest in Spring 2021, before becoming unwell with Covid19.

6 weeks after leaving hospital in Kathmandu he won the NOMAN, Barcelona to Ibiza rowing race in 93 hours and came second in the 2022 edition of the Talisker Atlantic Challenge in the 8th fastest time of all time.

Oliver believes it is important to have a dream. His dream is to climb an 8000'er without supplemental oxygen or Sherpa support and to complete a cross continental cycle ride and then a grand climb like one of his heroes, Goran Kropp.

He lives in London, but is often found in the Lake District or Cairgngorms when not on expedition.

Top notch; First class; Unparalleled; Exceptional - Choose your superlative and True Summit Adventures meets and exceeds it!  My sons and I recently returned from another trip with them, this one trekking and mountaineering in the high Himalayas.  Oliver and his team are not only world-class expedition leaders, they are superb and charming hosts who provide a level of personalized service and attentiveness rarely found in such operations. They really make an effort to ensure the team bonds, and usually lifelong friends are the result. TSA turns a memorable trip into the trip of a lifetime. I cannot recommend TSA enough!

George K

Oliver is a great guide and has his heart in making everything work. My company has used True Summit for several excursions, and I joined the Kilimanjaro climb with my son which was not only epic but meticulously organised.

Paul O

Oliver organised the most awesome expedition. Not only a great guide he is also a master in logistics. Everything worked like a Swiss watch.

Farzin P

I have to give a shoutout to Ollie, the owner of True Summit Adventures, who joined us on the trip. He was an incredible guide, knowledgeable, personable, and made sure that every aspect of the trip was exceptional. His enthusiasm and passion for the outdoors was contagious, and he went above and beyond to ensure that everyone had a great time. Overall, I can't recommend True Summit Adventures enough.

Wayne MK

True Summit Adventures is the place to go for the most transformative expeditions. Oliver is so knowledgeable on mountaineering and I felt safe and cared for the entire trip despite never having climbed before.

Sophie M

Every part of the trip was amazing and very well organised. Thank you for such a life changing trip!

Toufic Y

Travelled with True Summit to Kilimanjaro and Everest; what an incredible experience. Would recommend to any adventurer. 

Sterling M

Absolutely great experience. True individual approach from Oliver and his team. Will join again for sure 👌👍

Dmitry S

100% highly recommend. I have done two treks with Ollie (and have two more scheduled!).  In June, 5 friends and I tackled Kilimanjaro with him and we all summited.   The reason I keep going with Ollie is that he has made these trips fantastic.  We don't have to worry about anything -- he takes care of everything 100% -- all I have to do is be in half-decent shape and show up.  I trust not just that everything will be very well organized, but that we will be safe -- both in terms of being on a mountain adventure but also in terms of being in a foreign country doing so.  The teams that Ollie has produced to support our treks has been outstanding, and Ollie really just managed everything.    I would give Ollie 10 stars if I could.  As a 53 year-old guy who got to mountaineering late in life, I can't recommend Ollie highly enough -- he just makes everything easy and great.

Neal G

Ollie has led several personal expeditions for me including the Dolomites and Kilimanjaro, and more recently a corporate team building activity in Scotland. The bespoke trips that True Summit Adventures offer are ideal for my friends and I who have intensely busy schedules and are located all over the world. Ollie navigates around the availability, geographical and varying fitness level hurdles with patience and still manages to provide an all-encompassing, breath taking itinerary of hiking and fun activities along the way. The trips have provided memories for a lifetime, thank you Ollie. I look forward to Everest Base Camp next year!
