Testimonials For ISM

Fantastic trip, both Steve and Sandy were amazing! Wholeheartedly loved the trip, already looking at doing another one!

Edward (2017)
Summits & Skills 4000m (Instructional Course)

The classic alpinism course last week led by Swedish Daniel was excellent! The itinerary was really well planned taking into account the less than perfect weather and the abilities and aspirations of the group - we all learned loads.

Chris Ward
Classic AlpinISM (Instructional Course)

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.
