Testimonials For ISM

Please pass on my very, very sincere thanks to Thomas, Daniel & Christian. 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.

“What an incredible week learning the basics of Mountaineering. The course is perfectly balanced between summiting high alpine peaks and learning rope, climbing and glacier skills.

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 in 2022!”
