Who’s Behind Monkey Mountaineering?
Meet Sam Marshall: The Veteran Mountaineer Behind Monkey Mountaineering
Every great adventure company has a story and a purpose — and for Monkey Mountaineering, it all starts with Sam Marshall, a seasoned mountaineer, passionate explorer, and proud British Army veteran. If you’re curious about our mission, you can also read What is Monkey Mountaineering?.
After nearly three decades of service in the Army, including 22 years as an aircraft engineer and senior leader in high-pressure environments, Sam swapped helicopters and hangars for high peaks and remote trails. His mission? To share the life-changing power of the mountains with everyone, from first-time trekkers to seasoned climbers.
A Life of Service and Adventure
Sam’s love for the mountains was forged long before Monkey Mountaineering began. During his Army years, he thrived in extreme conditions, mastering leadership, teamwork, and meticulous planning in some of the world’s toughest environments.

These skills laid the foundations for leading safe, inspiring mountaineering expeditions today.
Leaving military life didn’t dampen his appetite for challenge — it fuelled a new purpose: helping others discover what’s possible when you push beyond your comfort zone. That vision is alive in every Monkey Mountaineering trip.
The Monkey Mountaineering Difference
Monkey Mountaineering isn’t just another adventure company. Under Sam’s watchful eye, every expedition is planned with military-level care and the robust safety standards of British Standard 8848. But adventure, for Sam, goes beyond risk management — it’s about growth, connection, and perspective. He believes time in the mountains has the power to build resilience, spark confidence, and reconnect people with the wild and with each other.
More Than Mountains: A Legacy of Respect
Sustainability and community matter too. Sam ensures Monkey Mountaineering operates responsibly, aligning with the United Nations Sustainable Development Goals, employing local guides, and championing the Leave No Trace ethos. It’s adventure done right — for you and for the places you explore.
