Go Trek Guides.. Climb Among the Best!

Our guides have climbed extensively throughout the world and have considerable training and professional leadership experience nationally and internationally. We partner with guides who are not only highly experienced but who are native to their respective countries.


Romulo Cardensa

Romula Cardensa

Romulo is one of the most experienced professional mountain guides in Ecuador and one of the pioneers of mountain guiding in the Ecuadorian Andes and beyond. His reputation and passion for the mountains drove Craig Van Hoy and Go Trek to enlist his special services. He climbs and guides not for the job, but to help participants fulfill their dreams and find new routes and new personal summits. Romulo is fluent in English and has been climbing and leading groups around the world for more than 30 years. During his vast mountaineering career, Rómulo became the first Ecuadorian to reach the summit of Mount Vinson and Denali. In addition, he’s an avid photographer, focusing his camera on Andean culture, flora and fauna of Ecuador.

matt farmer

Matt Farmer

Go Trek’s Craig Van Hoy recruited Matt because the man can do it all – and he’s got that “can’t wait” enthusiasm to get on the next mountain. Farmer has a solid background in all disciplines of climbing and particularly enjoys long alpine rock and ice climbs as well as ski-mountaineering.  Matt welcomes the chance to share with others the challenges and subsequent rewards of moving through technical terrain in the mountains. Level III avalanche certification and medical training such as EMT and OEC certifications complement his diverse skills as a climber and guide. These qualifications form a core of competence which ensures a fun time in the mountains whatever the itinerary. Matt is IFMGA certified and is working on his full AMGA certification.



doug ironside

Doug Ironside

Doug’s uncanny ability to communicate his knowledge of outdoor recreation skills to climbers and trekkers of all ages was a logical fit for Go Trek and Craig Van Hoy. Doug’s vast experience in snow sports ranging from snowshoeing to skiing allows all outdoors enthusiasts to become more adventurous in a safer manner. He’s been guiding outdoor recreation in the Pacific Northwest for more than 20 years and his avalanche safety class has brought national acclaim. Doug takes his clients beyond basic “snow science” to study how avalanches form, where they form and how to assess their potential. In addition, he explores the human behavior related to avalanches – how decisions are made, how groups operate, how real or perceived “peer pressure” is best handled on the slopes. Doug is the co-facilitator of the annual Outdoor Orientation Odyssey at Reed College in Portland.

He knows the Museum of Anthropology in Mexico City like the back of his hand and accompanies our guests even in the mountains.

Scott Wazny, a Portland resident and snowboard instructor at Mt. Hood, is one of the reasons Go Trek’s custom climbs are so varied and instructional.

Aconcagua along with the three highest points on the African continent – Mt. Kilimanjaro, Mt.
