The southern part of the Broumov Walls - located at the Polish-Czech border - contains their highest summits as well as a stunning rock arch.
The broad summit of Božanovský Špičák - at 773m the highpoint of the Broumov Walls - boasts several rock formations making up what is known as a "zoo" as well as providing views toward the Stołowe Mountains, southeast from Machov Pass (which sits at the foot of Božanovský Špičák). However, a much more attractive summit is Koruna (Crown), at 769m the second highest hill in the Broumov Walls. This is a captivating mountain, especially while viewed from the southeast. It rises over its foot by more than 300 metres, which means that it is actually taller than the highest summit nearby, Szczeliniec Wielki in the Stołowe Mountains.
Near the summit of Velká kupa (708m), about a half-hour walk west of Koruna sits one of the most interesting of the countless rock formations scatterred throughout the Broumow Walls: Kamenná brána, i.e. Stone Gate.
