Climbing "Kolmá hlína" (which translates roughly to "Perpendicular Clay") in the "Strašidla" (Ghosts) crag is a classic, easy route, rated a 3. It's a great option for beginner climbers or for a warm-up. Expect relatively slabby terrain with good holds, likely requiring some basic footwork and balance. The rock type is probably sandstone, common in many Czech climbing areas, so grip might be high, especially when dry. Given the low grade, the focus will be on enjoying the exposure and practicing basic climbing techniques rather than tackling any challenging moves. The "Strašidla" area itself likely offers a spooky or evocative atmosphere, given its name, adding to the overall climbing experience.
