Veliko vrilo, Natural pool in Civljane, Croatia
Veliko vrilo is a natural spring in Croatia that forms a clear pool of water fed by underground sources. The spring feeds into rivers that flow through the region and provide water to nearby communities.
The spring has supplied water to the region since ancient times and shaped how local settlements developed. For generations, residents have relied on its consistent flow to water their fields and sustain their communities.
The spring represents a central gathering point for regional celebrations and connects multiple villages through its shared water resources.
The location is accessible by foot, but the path goes through hilly terrain and can become slippery after rain. Sturdy walking shoes and plenty of water are helpful for a comfortable visit.
Beneath the water surface, a remarkably large opening leads into a hidden network of underground channels and chambers. Divers and researchers explore these submerged passages to understand the hidden geology beneath the pool.
