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.

My very, very sincere thanks to the ISM Guides. They are truly quality people! Patient, understanding, professional, and wonderful ambassadors for your company. I have experienced many guides over my 50 years in climbing and they rank right up there with the very best.Mt Blanc Special
