Climbing "Lehátko" (grade 6-) in Kostka is a rewarding experience. The route offers a mix of technical face climbing and slightly overhanging sections. Expect delicate footwork and precise hand placements, especially on the crux. The rock is generally solid, though be mindful of occasional loose holds. The exposure is moderate, adding to the thrill. Overall, a fun and challenging climb for climbers comfortable at the 6- grade.
