Climbing "Hliněná cesta" (Grade 4) on Vlčí stěna is a classic introduction to Czech sandstone climbing. The route, whose name translates to "Clay Road," offers a satisfying experience for novice climbers. While not particularly long, it provides enough exposure and interesting holds to make it memorable. The crux likely involves navigating the characteristic sandstone features, finding solid placements for your hands and feet amidst the often-slippery surface. Expect some thoughtful stemming and bridging techniques to be required, especially if the sandstone is damp. The views from the top, showcasing the surrounding Bohemian Switzerland National Park, are a well-deserved reward for the effort. Remember to bring slings and potentially some cams for protection, even on a Grade 4, as bolting can be sparse. Overall, "Hliněná cesta" is a good choice for those looking to cut their teeth on trad climbing in a stunning and historic location.
