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

Clare
Summits & Skills 4000m (Instructional Course)

The course was excellent, lots of variety and provided me with a good range of skills. Loved reaching the summit of the 4000m peak for such a nervous and unconfident novice like me, I gained a real sense of achievement from the ascent and the whole week. Huge thanks.
