Testimonials For ISM

Thanks for a great week, in some pretty challenging and extreme conditions. Thanks for keeping us safe, teaching us loads, and being all round fantastic fun. I'd look forward to coming on another trip with you guiding.

Steve

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

Clare
Summits & Skills 4000m (Instructional Course)

Our three guides were all excellent: Thomas, Phil and Paulo. I can't speak highly enough of them. They were all good company and superb climbers, and patient with us all.
