Today, I tackled 'Zapocený žlábek' (Sweaty Groove), a grade 4 climb in the 'Velký hrádek' rock formation. It was a fantastic experience, offering a good challenge without being overly intimidating. The rock was solid, and the holds were generally positive, although some sections definitely lived up to the 'sweaty' part of the name, requiring a bit more effort and careful footwork. The views from the top were well worth the effort, overlooking the surrounding countryside. A classic climb and a must-do for anyone visiting 'Velký hrádek' looking for a moderate challenge.
