Tackling 'Var. Kritik der reinen Vernunft' (Grade 7) at Kletterfels Reismühle Rechter Teil is an experience that truly tests both body and mind. The route's philosophical moniker, a variation on Kant's 'Critique of Pure Reason,' feels almost ironic. Is it a critique of my pure climbing reason, I wonder, as I eye the intimidating sequence? This Grade 7 ascent demands precision. The rock, typical of Kletterfels, offers subtle holds and requires delicate footwork. There's a particular section – a series of small crimps leading to a committing mantelshelf – that serves as the crux. It's not just about brute strength; it's about finding the elegant solution, the 'pure reason' of movement. The struggle is real, a dance between gravity and determination. Each move is a problem to solve, a tiny philosophical question. Reaching the anchors, with the sun on my face and the valley stretching below, brings a profound sense of accomplishment. It's a 'critique' that I've passed, a testament to focused effort and the joy of overcoming a challenge. A memorable route, not just for its physical demands but for the thoughtful challenge it presents.
