Climbing 'Nebeské zvony' in the 'Nebe' (Heaven) climbing area is a delightful experience. This route, graded a 4 (UIAA), offers a great introduction to the area and is perfect for beginner to intermediate climbers. The rock is generally solid, with ample holds and good protection. The crux is usually a small overhang that requires a bit of technique, but overall the climb is enjoyable and not too strenuous. The views from the top, overlooking the surrounding landscape, are a worthwhile reward for the effort. It's a classic route in 'Nebe' and a great way to spend an afternoon, especially if you're looking for a relatively easy and scenic climb.
