Slap Boka
Slovenia's tallest waterfall bursts from a narrow slot in the rock face of the Julian Alps, forming two separate jets in high water that merge into one lower down. A short trail from the Bovec-Kobarid road reaches a viewpoint with the peaks of Triglav National Park rising behind it.

Boka Waterfall is the tallest of the 5 waterfalls we cover in Slovenia. As a plunge waterfall, water leaves the rock entirely and falls free through the air.
