Climbing "Poslední výzva" (grade 6) in Kobyla was a rewarding experience. The route follows a crack system up a relatively steep face, demanding solid technique and good footwork. The rock is generally solid limestone, but careful placement is still necessary, especially higher up where the holds become a little less obvious. The crux section involved a tricky traverse to the left, requiring a precise high foot and a controlled reach. Overall, it's a classic Kobyla climb, offering a good challenge for climbers comfortable at the grade, and definitely deserving of its popularity.
