Testimonials For ISM

This was a fantastic trip. Paolo was excellent. The accommodation great. All helped along by wall to wall sunshine, stunning arctic scenery and some superb snow, so no problems as far as I'm concerned.

Steve (2017)

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.

David Hughes

Brilliant!! I was a walker at the start of the week. By the end had been on glaciers and climbed a 4000m peak!! It was a wonderful, wonderful, experience which i will never forget. It was excellent value for money and I hope to be joining you for years to come.
