Koby Yudkin
Koby’s love for the mountains began in high school when an outdoor program first introduced him to climbing and mountaineering. From rime ice covered days on Mt. Hood to aching fingers after a weekend of climbing the volcanic tuff at Smith Rock, he quickly realized that challenge and joy often come hand in hand in the outdoors.
His pursuit of adventure carried him across the country to Bates College in Maine, where he earned a degree in Environmental Studies in 2017. Immersed in the rugged traditional climbing ethic of Northeast climbing, he cut his teeth on the granite walls and alpine terrain of the Mt. Washington Valley—a place that not only honed his skills but also launched his guiding career.
Now based in Portland, Oregon, Koby guides rock climbing, alpine climbing, and backcountry skiing adventures throughout the Cascades and beyond. Whether it’s long summer days climbing in the alpine or early morning missions to ski first tracks, he’s passionate about helping others experience the same sense of adventure, connection, and discovery that first drew him to the mountains.
