Climbing "Oppurg Riss (Prommer)" (grade 7-) in the Militärklettergarten is a fantastic experience for anyone looking to delve into classic crack climbing. Graded 7- on the UIAA scale, it's a demanding yet incredibly rewarding route that primarily tests your crack technique – think precise finger and hand jams, good footwork, and a fair amount of endurance. It's less about raw strength on tiny crimps and more about the art of wedging yourself into the rock. The route feels sustained, requiring continuous effort and the ability to read the varying width of the crack. It's a true test piece for its grade and a must-do for crack aficionados visiting this historic climbing area.
