Climbing Half Dome, in Yosemite National Park, via the Cables route has been a bucket list hike for people since 1875, when George Anderson first put the route up. These days around 300 people a day during the summer make it o the top. The Cables route involves first climbing up several hundred feet of granite stairs to gain the top of the Sub-Dome. After which, hikers get to the bottom of the Cables themselves. 400 vertical feet of steel cables, 4 feet apart and about 4 feet off the ground, punctuated every 10-15 feet with 2x4" wooden boards for foot purchase. The experience gets even the most seasoned hiker out of their comfort zone. For the past 4 years, I've had the pleasure of guiding groups of people up to the top and helping to get them out of that comfort zone and into a new one. Tears of fear, joy, and pure adrenaline make this job one of the most memorable that I've ever had. The views aren't too bad either.
