Climbing "Das grosse Aufwärmen" (The Big Warm-up) on the Arnstein Turm is a fantastic experience for climbers operating in the grade 5 range. The route typically involves a mix of interesting holds, stemming opportunities, and generally solid rock, making it a pleasant and engaging climb. The position on the Arnstein Turm itself adds to the experience, often offering stunning views of the surrounding landscape. While grade 5 isn't overly strenuous, it still requires good technique, thoughtful footwork, and a degree of comfort with exposure. The climb is usually well-protected, providing a sense of security and allowing climbers to focus on enjoying the movement and the overall experience. It's a classic, accessible route that serves as a great introduction to multi-pitch climbing or simply a satisfying single-pitch outing on a beautiful tower.
