Meet the Team

We’re primarily a family unit with the support of some fantastic individuals who help make Trek Scotland unique. 

Our Guides

Myrddin Irwin

Lead Guide and photographer. Besides having a passion for the outdoors, mountain environments and bushcraft, Myrddin [Merlin] is a Mountain Leader and professional photographer who specialises in landscape and biographical photography. During his early professional photography career he worked as a studio photographer which involved photoshoots with adventurers such as James Cracknell. Myrddin identifies himself as a passionate 'Gear Nerd' and heads our relationship with Ultralight Outdoor Gear and the reviews and testing of equipment we do for them.

Simon Greaves

Consultant Senior Guide and founder of Trek Scotland. Qualified and highly experienced Mountain Leader with a life time of mountaineering throughout the British Isles, Europe and as far afield as New Zealand. Simon’s longest trek involved leading two people on a successful 44 day epic self supporting trek across the complete High Route of the Pyrenees. It was on this trek that he formulated the idea for Cairngorm Treks (now Trek Scotland) and making the experiences as lightweight and comfortable as possible. Originally from the Peak District National Park, Simon has spent much of his life being involved with outdoor pursuits and education, including rock climbing, canoeing, dingy sailing, caving and mountain biking. Now based both in the northern Cairngorms National Park and France, Simon has been involved with guiding in the Scottish mountains for the past 15 years. His main passion is to provide opportunities for others to enjoy and benefit from the great outdoors, whatever their abilities or limitations.

Matt Reynolds

Matt started guiding with us in 2021 after meeting Myrddin on a Winter Mountain Leader course. He's also based in the Cairngorms and runs his own guiding business, Lost Sheep Guiding. An experienced mountaineer and climber, Matt has trained and worked as an outdoor instructor at various outdoor centres. He is passionate about nature connection and getting people engaged with the outdoors, to experience the healing it can offer. This is strongly within our ethos and a reason why Matt is such a great fit for Trek Scotland.
