Summits & Skills 4000m (Instructional Course)

I just wanted to thank you as well as Mark, our guide for the amazing week. The course was well organized and was just perfect for a beginner to mountaineering. We couldn't have wished for a better adventure. The memories are irreplaceable.

EP

Neil, our guide for the week, was exceptional; a true professional, a huge inspiration and just great company. He shared so many useful tips with us and had great stories to share too. Looking forward to booking another course with ISM!”
