Rocktown Climbing Gym isn't like most other gyms—in fact, it's not really even a gym at all. All 52 of Rocktown's indoor climbing routes live inside a repurposed grain elevator, which gives them room to soar as high as 110 feet vertically. Some routes uncoil to 140 feet in total length, complete with zigs and zags, multiple pitches, and even horizontal portions 100 feet above the ground. While aerial theatrics and bouldering might be reserved for experts and ambitious slugs, there's plenty to offer beginners, too: auto belays and instruction are available to novices and first-timers.

As exciting as the gym is on the inside, it's a visual marvel from the outside. The gym can be spied from miles around thanks to an enormous, vibrant mural that adorns the outside of the silo cluster. An additional 13 routes can also be found outside, giving experts the extra challenge of contending with wind, ice, and comets.
