The spring is a classic example of a karst siphon, where water emerges from a subterranean limestone channel.
During heavy rainfall, the spring can discharge large volumes of water, sometimes overflowing the immediate pool area.
The Krka River here is one of the few rivers in the region that features significant tufa (travertine) deposits along its downstream path.
The temperature of the water remains consistently cold, usually around 9-10 degrees Celsius, regardless of the season.
Izvir Krke is the primary karst spring of the Krka River, emerging directly from beneath a dramatic limestone cliff face. The water flows into a crystal-clear, emerald-green pool that maintains a constant low temperature throughout the year. Located in the village of Gradiček, the site serves as the hydrological starting point for the Krka river system in Slovenia. The surrounding environment consists of lush riparian vegetation and historic water-mill infrastructure. The spring is characterized by significant fluctuations in discharge volume depending on seasonal precipitation. It is a protected natural site noted for its high geological importance in the Dolenjska region.

Bring waterproof footwear if you plan to walk along the occasionally muddy riverbank paths.
Visit during the spring or autumn to witness the highest flow rates from the rock face.
Respect the local private property boundaries surrounding the spring area.
Attempting to swim in the main spring pool, as the current and cold temperatures are hazardous.
Stay on marked paths to protect the delicate riparian soil and native flora.
