Rock climbing is, well, climbing rocks. It sounds easy enough, but sounds can be awfully deceiving as can those mysterious little crevices that a skilled climber uses to support her entire body weight with only a few fingers. It may just be the most physically and mentally demanding activity on the face of the planet. Literally. Fret not, however, as rock faces, just like climbers, come in all shapes and sizes. Find the perfect one and get scrambling.
