This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.
How to get there
Via the narrow road to the village of Cetina (~7 km N of Vrlika, turn off the D1 at restaurant Ivan). Small car park and viewpoint next to the Serbian Orthodox church, then a short walk to the spring pool. According to Parks of Croatia (Nov 2026) the Ministry of Environmental Protection and Green Transition is not the authority for permits or conditions for diving in the spring: ask Hrvatske vode (Croatian Waters) about access, water protection and any permits. As a nature monument and drinking-water source, activities that may harm the spring, its ecosystems or the water quality are considered undesirable.
