Thanks for organising an excellent week. The course format & accommodation was perfect. The guide was outstanding & gave us a full week of constructive tuition. I was able to put this training into practice the following week when I met up with a friend.Classic AlpinISM 2026

Perfectly paced and tailored, great variety of skills learned. Guiding and Instruction? Our ISM Guide was fab! Everything was pitched at the right level (no pun intended), safety was always paramount and everyone had so much fun learning everything.Summits & Skills 4000m
