Guy Cotter

Guy Cotter

CEO, IFMGA Mountain & Ski Guide

Guy's whole life has been spent in the mountains - in New Zealand, the Himalayas and many other mountain ranges around the world. Born in southern New Zealand, he was introduced to the outdoors at an early age where a fascination for the mountains was fostered. He feels these days spent as a young explorer were a solid foundation for his future climbing career.

His passion for the mountains eventually saw him focus on a career as a mountain guide where his skills earned him a position working alongside fellow Kiwis Rob Hall and Gary Ball when they established their Everest guiding company, Adventure Consultants, in 1992. Guy excelled as a high altitude guide and, along with Rob and Gary, led the team to the summit that year on the first commercially guided expedition on Everest.

After Rob Hall was lost in the tragic events on Everest in 1996, Guy took over Adventure Consultants becoming Director and CEO, and has grown the company in to what it is today. For more on the history of Adventure Consultants, click here.

In addition to guiding, Guy's skills are in demand as a high altitude cameraman, running film projects in the Southern Alps (or on the Seven Summits), training corporate groups and meanwhile ensuring the list of exciting destinations for Adventure Consultants' clients is always growing!

For Guy, the pleasure of operating an adventure business lies not in the financial rewards but rather in helping clients achieve their dreams.

  • Q & A

    Guy Cotter AICWhat do you love most about guiding?

    I share a passion with the team here at Adventure Consultants to be the best we can be at what we do. We all get a lot out of seeing our clients have the best experience of their lives.

    It’s that look of elation and seeing them evolve as personalities through the mental challenge of mountaineering that gets me.

    Outside of climbing how do you like to spend your time?

    Guy Cotter Ski ActionI'm based in Wanaka, NZ, which is close to Mt Aspiring National Park and set on the shores of beautiful Lake Wanaka. With several ski resorts, lots of crags, rivers, paragliding, mountain biking galore; Wanaka offers everything I could ask for in providing an adventurer’s daily fix.

    I try to balance my time between steering the company and fulfilling my love of rock and mountain climbing as well as mountain biking and photography. Every now and then I take a complete break, disconnect from the modern world, and head to the South West Coast of the South Island to go fishing and diving from my dingy.
