All Four Seasons (AFS) Mountaineering provides a range of hill, moor and mountain adventures and skills training to enable you to become more confident in the great outdoors and explore more. Dr Fabian Seymour established AFS Mountaineering in 2016 to combine his passion for teaching, science, nature and the mountains, and bring that to others. His main passions are providing people with the confidence to go out exploring via navigation courses; providing winter skills courses and introducing people to the wild side, and of course Munro bagging!

We provide courses, private guiding, private courses, night events, wilderness treks, climbing and winter mountaineering activities. There is so much to explore. 

Please note: Although all instructors hold a fully enhanced DBS Certificate, we do not hold an AALA License, so activities are restricted to adults. Under 18s are welcome to attend if accompanied by their legal parent / guardian. 


As the saying goes "Because in the end, you won’t remember the time you spent working in the office or mowing your lawn. Climb that goddamn mountain." - Jack Kerouac


It's all about you

You will get an experienced mountain guide who aims to provide:

  • An inclusive and encouraging atmosphere. We are LGBT+ and BAME friendly.

  • Quality courses that will equip you with tools and confidence to become a more independent hill walker, climber and mountaineer

  • Advice on equipment and hill/mountain craft for your own adventures

  • Recommendations for different regions to visit which match your interests

  • Information about the landscape, flora and fauna we may encounter plus other interesting historical snippets if applicable!

  • Advice about accommodation nearby and transport options based on your budget

What I can't guarantee is the weather which, in Britain, is notorious!

"Excellent mountain guide - great local knowledge of the individual regions, especially Scotland. Great attention to detail, planning, navigation and safety. Sets a pace that suits your ability yet challenges you out of your comfort zone also. Happy to impart technical knowledge and signpost you to relevant training and development. Oh yes, good fun and great company. Highly recommended."

Managing Director

I've been out and about exploring the high places of Britain since 2001. I've worked with, and been a member of many University and other mountaineering clubs. I have a passion for enthusing others with the love of mountain environments and landscapes, and building people's confidence to get outdoors as a mountain guide.

My interest in the mountains began when I had the amazing opportunity to work in Antarctica (2001 – 2002) researching how life was surviving in one of the most extreme environments in the world. I have a PhD in molecular genetics and microbiology and have published peer-reviewed research articles.

I've climbed all of the 282 Munros (mountains in Scotland over 3,000ft), all of the other 3,000ft (+) peaks across England and Wales, as well as having explored many other wild areas across Britain. But I am equally happy exploring coast, moors, the enchanting and bleak plateaus of the Pennines, wild camping, exploring remote glens or climbing and scrambling crags and cliffs.

I hold the Summer and Winter Mountain Leader awards which are designed to ensure leaders have the necessary skills above and beyond what is expected to lead group walks and expeditions in the mountains of Britain and Ireland in summer and winter conditions. I also hold the Rock Climbing Instructor Award. I'm also a member of the Mountain Training Association and the British Mountaineering Council and undertake continuing professional development. I have a valid wilderness first aid certificate which is a requirement to holding the awards. I also hold a current (and transferable) enhanced DBS certificate and ​I'm insured to provide the range of activities within the remit of the Mountain Training Awards held​.

I'm accredited to provide BronzeSilver and Gold Navigator Awards and the NNAS Tutor Award through the National Navigation Award Scheme (NNAS) and I'm a member of the NNAS Board of Directors.
