On High Hills is owned and operated by Jonty Mills, a qualified Mountaineering Instructor and International Mountain Leader. We are based near the Cairngorms National Park in the Scottish Highlands.


Jonty has walked, climbed and ski-toured extensively in many parts of the UK, Europe including the Alps & Pyrenees, as well as further afield in the Canadian Rockies, the Moroccan Atlas and in Kenya. Despite this, the hills of the Scottish Highlands--home--remain firm favourites.


Jonty holds the highest UK award for all aspects of summer mountaineering, the Mountaineering Instructor Award (MIA), including multipitch rock-climbing and scrambling. He also holds the International Mountain Leader and UK Winter Mountain Leader awards. Check out this film to find out more:










Jonty is also a qualified medical doctor, and holds a current Outdoor Emergency First Aid Certificate. He has an interest in Mountain Medicine, and works as a tutor on the International Diploma in Expedition & Wilderness Medicine.
