The commune of Brenna is situated in a vast valley of Brennica, which runs through two distinct physical and geographical units. This makes the northern part considerably different in terms of its surface shape from the southern part; hence the big differences of the relative altitude in the area. The lowest point in the commune lies at the altitude of 300 m above the sea level in Górki Wielkie at the estuary of the Brennica to the Vistula, and the highest is the Trzy Kopce peak (1082 m above the sea level).
BŁATNIA (or: Błotny; 917 m above the sea level) – a peak in the Klimczok group of the Wisła Range of the Silesian Beskid.
TRZY KOPCE WIŚLAŃSKIE (810 m above the sea level) – a peak in the Równica range in the Silesian Beskid.
KOTARZ (974 m above the sea level) – the name denotes both a distinctive elevation in the main ridge of the Barania Góra Range in the Silesian Beskid, which is the highest in the part between the Salmopol Pass and the Karkoszczonka Pass, and the whole side ridge, which branches off from the peak in the north-westerly direction and lowers through the cirques of 918 and 828 m above the sea level to the bifurcation of the Brennica and the Hołcyna.
PRZEŁĘCZ KARKOSZCZONKA [THE KARKOSZCZONKA PASS] (729 m above the sea level) – a deep pass in the main ridge of the Silesian Beskid, between Beskid (860 m above the sea level) in the south and the Trzy Kopce (1082 m above the sea level) in the north. If you leave out the Brama Wilkowicka, Karkoszczonka is the lowest point in the Vistula (here: the Brennica) and the Soła (here: the Żylica) drainage basins. Thus it is the lowest and the most convenient route between Szczyrk and Brenna, used by the locals for centuries.
STARY GROŃ (792 m above the sea level) – a general name for quite a long mountain ridge in the Silesian Beskid in the Brenna area. The ridge goes northwards from the Grabowa culmination in the main ridge of the Silesian Beskid and separates the valleys of the Leśnica and the Hołcyna. The part of the ridge described by that name is almost sloping, though narrow; the section between the slope of Grabowa and the elevation of Horzelica is nearly 3 km long.
ORŁOWA (813 m above the sea level) – a mountain in the Silesian Beskid, in the northern part of the Równica Range. Orłowa is a vast mountain, separated from Równica by the deep Beskidek Pass (662 m above the sea level).
ZEBRZYDKA, on some maps also: Rzebrzydka, Rzebrzyczka or Rzybrzyczka (579 m above the sea level) – a small elevation in the form of a well formed mound with steep slopes, the last peak in the Błatnia (Błotny) sub-range, the Barania Góra Range in the northern part of the Silesian Beskid. It is a distinctive mountain, dominating over Górki Wielkie in the east.
