ABOUT
AFS MOUNTAINEERING
Established in 2017 by Fabian Seymour, All Four Seasons (AFS) Mountaineering combines a passion for teaching, science, nature and adventure to help people explore the outdoors with confidence. From Fabian's early adventures on the North York Moors as a child to scientific research in Antarctica to mountaineering across Britain, a lifelong love of wild places inspires everything we do.
"Working in Antarctica really awakened my passion for adventure, snow and ice. But what I enjoy most is helping people develop the skills and confidence to explore independently, whether that's navigation, winter walking, climbing or Munro bagging!"
We offer navigation courses, winter skills, rock climbing, private mountain guiding, wilderness treks and unique dark skies experiences, alongside bespoke adventures for individuals and groups.
We primarily work with adults. Under-18s are welcome on suitable activities when accompanied by a participating parent or legal guardian. Our instructors hold enhanced DBS certificates.
It's all about you
Our experienced, qualified instructors aim to provide:
-
A welcoming, inclusive environment for everyone, including LGBTQIA+ and welcome people of all backgrounds and ethnicities.
-
Practical skills and confidence to become more independent hill walkers, climbers and mountaineers.
-
Equipment advice and mountain knowledge to help you plan your own adventures.
-
Local knowledge, from recommended routes and destinations to wildlife, landscapes and history.
-
Practical guidance on accommodation and transport where needed.
We can't guarantee the British weather, but we'll do everything we can to make your experience enjoyable, rewarding and memorable!
