Ðulin ponor

Ðulin ponor is an extensive cave system in Ogulin featuring underground streams, lakes, and multiple passages throughout its network. Waterfalls flow through different sections, creating dynamic water channels carved into the rock.

Initial exploration of the cave began in 1926 when Josip Poljak first entered the system. Major research expeditions took place in the 1950s, significantly expanding understanding of its layout and formations.

The name comes from a local story about a girl named Đula who fell into the abyss long ago. Visitors notice how this tale connects to the place and the rocky formations around them.

The cave maintains steady cold conditions year-round, making it physically demanding to explore. Professional guides are essential since water hazards and narrow passages require expertise and proper equipment.

The cave contains a distinctive section called the Great Braid featuring a series of cascading waterfalls flowing in succession. This impressive water display is a characteristic that sets the cave apart within the region.
