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, and in particular the Cairngorm mountains near his 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. These are the professional awards designed for those leading trekking groups anywhere in the world, in all seasons.
