Meet the Team!

Who are we?

We’re primarily a family unit with the support of some fantastic individuals who help us make Trek Scotland unique and personal. At our core, we are a small family venture, and we run Trek Scotland from our home in Grantown on Spey. We are Myrddin and Jess, lovers of outdoor adventure and photography, parents to two wonderfully fiesty children, and jugglers of family life and business! You can find out more about us and the rest of the Team below.

Jess Greaves

Operations Manager

Jess took over the running of Trek Scotland in 2021, having being involved since 2014. She organises treks, keeps the website updated and deals with bookings, amongst all of the other admin involved in running a small business! Her background is in nature conservation and photography, and she is an artist at heart with a passion for creating imagery that celebrates nature.

Myrddin Irwin

Lead Guide

Myrddin is our Lead Guide, meaning he plans our routes and figures out where to explore next! He’s also a talented photographer with a passion for the outdoors, mountain environments and bushcraft, specialising in landscape and biographical photography. 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.

Matt Reynolds

Mountain Guide

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.

Simon Greaves

Consultant Guide

Simon founded Trek Scotland and now works for us as a Consultant Guide, with decades of guiding experience in the Scottish Highlands. He is a qualified and highly experienced Mountain Leader with a lifetime of mountaineering throughout the British Isles, Europe and as far afield as New Zealand. His main passion is to provide opportunities for others to enjoy and benefit from the great outdoors, whatever their abilities or limitations.

Our Roots

Simon & Kerry Greaves


Trek Scotland exists because of Simon and Kerry who founded, what was then, Cairngorm Treks in 2014. They saw a gap in the market for guided multi-day adventures with full provision of wild-camping equipment. Not just any equipment though, lightweight and high quality gear to make trekking as comfortable and manageable as possible. Simon conceived this idea when guiding a 44 day self-supporting trek across the complete High Route of the Pyrenees in 2013. The attention to detail they gave to setting up Trek Scotland is very much in our roots today and one of the reasons we’ve built a solid repuation for multi-day guiding.
