Exum is the premier guided climbing experience for hikers and mountaineers planning to summit Grand Teton. Despite my lack of technical climbing experience, the guides at Exum helped me to acquire the skills and confidence necessary to make my way to the top of this mountain. I signed up for one day to learn about self arrest and hiking in the snow and two days of rock climbing and repelling. The fourth day we started our ascent to the Lower Saddle and camped out, and the fifth day we made it to the summit. I asked too many questions. The guides answered them all. I didn't have all my gear, they allowed me to rent what I forgot. I needed sunscreen, they provided it. This company definitely helped me bridge the gap from recreational weekend hiker to understand more about mountaineering and rock climbing. I don't understand the rating system for rock climbing. But it was hard. If you are afraid of heights, do your research to fully understand what will be expected of you before you reach out to them. Assuming you are willing to train and acquire all the tools they recommend, this will be the adventure of a lifetime and I can't speak more highly of this company. They didn't just show me the way to the summit, they fostered a sincere relationship where I fully trusted them, and also explained that the journey wasn't just about reaching the summit. Next time when I come back I'll bring a few more friends with me. This is the service provider you need to use for your next adventure in the Tetons.
