"On July 4, 2011, I stood on the summit of Mt. Rainier, my two best friends next to me. At age 25, I had been hiking and climbing for years in New Hampshire, yet that day I found myself in the dramatic terrain of the Cascades. Rather than hiring a guide for Rainier, we took a prep course, studied Freedom of the Hills and practiced in the Whites. I was hooked. Since then I've lead trips back to the Cascades (Hood, Baker, Silverstar) to Ecuador (Cotopaxi, Chimborazo), Patagonia (Cerro Electrico), and a spent my honeymoon crossing the Alps, culminating in an ascent of the Matterhorn. I joined the AAC in 2010 and actively volunteer at local climbing events. In 2015 I founded The Notch Hostel, a successful business located in the White Mountains that hosts thousands of hikers, climbers, and travelers. I am extremely passionate about climbing and love helping people achieve their goals in the mountains with North Ridge Mountain Guides."


Justin Walsh has been climbing in the White Mountains for close to ten years.  Whether it's multi-pitch rock on Cathedral, waterfall ice in Crawford Notch, or a Winter presidential traverse, Justin is at home in these mountains.  Beyond the Whites, his passion for climbing has taken him around the world.  He's crossed dozens of glaciers from Switzerland to Patagonia and ascended peaks as high as 20,500' (Chimborazo).
