Izvir Krupe (TILOS / no diving)
Diving is prohibited. The 1997 Semič municipal decree declaring the Krupa a natural landmark bans boating, rafting and sport diving in the spring, riverbed and buffer zone (Art. 4). The Krupa rises from deep pools below a 30 m cliff and is Bela krajina's largest spring; the Slovenian diving atlas describes the pool (up to 7 m, about 10 °C, dense plants) but notes there is no real underwater cave. The spring lake holds a known site of the cave mussel Congeria kusceri.
