Climbing "Blau" in the Bundesheerklettergarten (G) is a pleasant and accessible route, perfect for warming up or for climbers new to the 4+ grade. The route generally features well-placed holds and a fairly consistent angle, making it a good choice for practicing technique. Expect a mix of juggy holds and some smaller crimps, requiring a bit of thoughtful footwork. The rock is generally solid and offers good friction. While not overly challenging, "Blau" provides a satisfying climb with a rewarding top-out. Remember to inspect the anchors and communicate clearly with your belayer. Overall, a fun and recommended climb in a well-maintained climbing area.
