Climbing "Čumák" (grade 6-) in the "Metro" crag is a memorable experience. The route, characterized by its distinct feature for which it's named (likely a protruding or snout-like formation – "Čumák" in Czech roughly translates to "snout" or "muzzle"), demands a good mix of technique and power. The rock quality is generally good, but pay attention to potential looseness or polished holds, especially near the crux. The crux move often involves a delicate balance or a powerful pull over the characteristic feature. Finding the right sequence and maintaining good footwork are crucial for success. The relatively short but intense nature of the route makes it a worthwhile challenge for climbers solid at the 6- grade.
