Opěrátko — 6, Kostka 6

Climbing 'Opěrátko' (graded 6 according to the UIAA scale) at the 'Kostka' rock formation is a classic Czech climbing experience. 'Kostka,' meaning 'cube' in Czech, is known for its compact and challenging routes. 'Opěrátko,' which translates to 'little backrest' or 'support,' likely refers to a feature of the climb itself, perhaps a small ledge or a slightly overhanging section that provides a feeling of, or requires, back support.

The climb itself typically involves a mix of face climbing and crack techniques. Expect small holds, requiring precise footwork and strong fingers. The rock is generally solid sandstone, offering good friction, but also demanding care in placing gear. Protection may be sparse in places, so good route-finding skills and a confident lead are essential. 'Opěrátko' is a rewarding climb that provides a good test of technical skill and mental fortitude for climbers operating at this grade. A successful ascent is a badge of honor for many Czech climbers.
