センの自然の驚異

Croatian Caves and Springs

The Velebit mountain range in the Senj region contains some of Croatia's most significant speleological sites. This collection features deep vertical pits like Lukina jama and Slovačka jama, which rank among the deepest in the world. The area is characterized by unique karst phenomena, including 'snježnica' ice caves that preserve snow year-round and natural freshwater springs. These geological formations are primarily located within the protected landscapes of Northern Velebit National Park.
