Kevin Blades

I have sometimes thought of going away, but I imagined that as a kind of holiday, a series of adventures like Bilbo's or better, ending in peace." - Frodo Baggins

"After last year's hiking and backpacking season I made the move to Kimberley, B.C., a small  town in the Purcell Mountains. For the winter I was forced to ski lot's of powder and fix broken body parts when I took the job of ski patrolling at the local hill (it was rough).  Since then I've been exploring the Purcells on ski, foot and bike waiting for the summer season to begin again."

Kevin has been working in the Outdoor Industry for more than 15 years and has guided trips in the Coast Mountains and the Rockies. Kevin is also a  Red Cross First Aid Instructor. 

He's also trekked the Tongariro Circuit in New Zealand, climbed Mount Kinabalu in Borneo, cycle toured S.E. Asia for a year and backpacked a number of never-before-done trips in the Canadian Rockies. He's trekked, cycled and climbed the world over  and wants to bring the fun, passion and beauty of our natural world to you.
