Climbing "Hrana" (Grade 3) in the "Metro" sector is a delightful experience for beginner to intermediate climbers. The route typically follows a well-defined edge (hence the name "Hrana", meaning "edge" in Czech). The holds are generally large and positive, making it physically accessible. The rock quality in "Metro" is usually quite good, offering solid friction. However, be mindful of potential polish in high-traffic areas. The crux of the climb often involves careful footwork and maintaining balance along the edge. Overall, "Hrana" is a satisfying and enjoyable climb, perfect for warming up or practicing fundamental climbing techniques in a relatively safe and controlled environment. Remember to always check the route and conditions before you start, and climb with a spotter if you are unsure.
