Svinjak, Mountain summit near Bovec, Slovenia.

Svinjak is a distinctive mountain in the Julian Alps near Bovec, featuring a sharp pyramidal shape and steep slopes on all sides. Its 1,653 meter (5,423 ft) elevation makes it a recognizable landmark in the surrounding Alpine landscape.

On the western slope lies the Čelo open-air museum, an Austro-Hungarian gun position called Stützpunkt Kal, built from November 1914 to spring 1915 in anticipation of Italy joining the Entente. Two 12 cm cannons were mounted there and, together with the Kluže fortress and Fort Hermann, guarded the border at the Bovec basin.

The name comes from *Svitnjak, 'the shining one', from svit ('dawn, light'), because the peak is lit by the rising sun as seen from Bovec. Its resemblance to the Slovene word svinjak ('pigsty') is coincidental. Locals pronounce it [sʋiˈnjaːk].

The main hiking route starts from Kal-Koritnica village at the lower elevation and climbs through forest trails with clear markings. The journey takes several hours and involves steep sections that require good fitness and careful footing.
