Izvir Bilpa (Bilpa spring cave)
Bilpa Creek flows out of a cave below a high rock wall above the Kolpa river, close to Spodnja Bilpa; the karst spring dwindles in dry periods and gushes after rain. The spring cave contains sumps separated by dry sections. In October 2022 sixteen divers of the state technical-diving unit and four cave-rescue divers trained here in cave-diving techniques beyond the sumps, including moving equipment through the dry part.
