“It was the highlight of our trip to Mammoth Lakes. Everyone felt challenged, but also safe and supported. The guides were so encouraging and knowledgeable. They spent a lot of time with us and we never felt rushed. We were all beginners, but were able to make it up to the top of every climb. It was so fun, and the views were incredible! Would highly recommend!”
