What Our Clients Say
"I scheduled a private backcountry ski day and could not have been more satisfied. Ben was patient, positive, and very knowledgeable in the field. I felt very safe and learned a lot in just one day. I would highly recommend Trillium Alpine Guides to everyone!"
Mary M. - First Tracks
“Koby was an expert in all topics covered. He took extra time to make sure everyone understood the skills being taught. Highlights for me were learning how to set snow anchors and crevasse rescue.”
Leslie F. - Crevasse Rescue Course
"I had a fantastic private ski tour with Ben - he was a great travel partner and we absolutely got the goods all around Mt. Lincoln and Judah! I learn a whole lot of uptrack tips & tracks from Ben's expertise. Good turns and smiles were shared!"
