Climbing "Temná hrana" (Dark Edge) in "Bludiště" (Labyrinth) is a classic Czech climbing experience. Graded at a solid 4, it offers a rewarding challenge for beginner to intermediate climbers. The route typically follows a prominent edge or arete on the rock face, requiring good footwork, solid handholds, and a decent head for heights. While not overly strenuous, "Temná hrana" demands focus and careful route finding, as the 'labyrinth' name suggests. The rock is generally well-featured, providing plenty of holds, but some sections may require a bit of careful stemming or smearing. The exposure can be considerable, adding to the thrill and requiring good rope management. Successfully topping out "Temná hrana" provides a satisfying sense of accomplishment and offers stunning views of the surrounding Czech landscape.
