Eisenerz, Austria
Rosslochhöhlen Klettersteig is a unique and spectacular 70-meter cave via ferrata in the Hochschwab group near Leopoldsteiner See in Styria, Austria. What sets it apart is that you actually climb through a deep mountain cave using fixed protection, making it one of Austria's most distinctive alpine experiences. The cave itself is the destination, and the route is exceptionally well-designed with perfect 5.0-star ratings. You'll experience vertical climbing inside the cave with exposure, bridges, and the unforgettable sensation of rock walls towering above you in dim light. The route demands commitment, solitude, and genuine climbing skill. 100 meters of actual via ferrata inside the cave over 1 hour of climbing (2.5 hours approach via hiking trail 822 or 4 hours via Kaiser-Franz-Josef Klettersteig, 2 hours descent), with 70 meters elevation gain overall. Difficulty D/E (hard to extremely hard), requiring solid climbing ability and no fear of vertical exposure. Critical warnings: there is no escape route once you enter the cave bottom, so if you complete the Kaiser-Franz-Josef Klettersteig first (a common combination), you must have strength remaining. Do not attempt the cave if rain is forecast or after rainfall, as the cave stays wet and rock becomes dangerously slimy, plus visibility worsens. One-way traffic rules mean you cannot turn back once committed. Ideal for experienced climbers seeking an Alpine adventure unlike most routes.
