Climbing "Delfíní skok" (grade 4) in "Delfínek" is a delightful and accessible experience. The route, true to its name ("Dolphin's Jump"), likely involves some dynamic movements or sections requiring a bit of a reach. Grade 4 indicates a relatively easy climb suitable for beginners or climbers looking for a warm-up or enjoyable cruise. Expect well-defined holds and generally straightforward sequences. The crag "Delfínek" (Little Dolphin) suggests a smaller, perhaps more sheltered climbing area, possibly with a focus on easier grades, making it a good choice for families or those new to outdoor climbing. Enjoy the 'jump' and the stunning views (if any) that Delfínek offers!
