Acceso y normas
- Sea diving: through a registered dive centre or diving club. Independent divers need an 'odobrenje za individualno ronjenje' from a harbour master's office (lučka kapetanija Pula, Rijeka, Senj, Zadar, Šibenik, Split, Ploče or Dubrovnik): per the ministry's page 2,400 kuna (~€320), valid one year — check the current euro fee. Mark your dive with an orange/red buoy (≥30 cm) or a dive flag; separate bans apply at wrecks and archaeological zones.
- Inland springs: the deep springs are protected (Izvor Cetine natural monument since 1972, Vrelo Une since 1968, Izvor Kupe in Risnjak NP) and often drinking-water sources. Swimming is banned at the Cetina spring (since 2022, 400 m downstream) and at Vrelo Une (entry €3). Divers were fined for unauthorised diving at the Cetina in 2009. No operator offers recreational spring dives: plan it as an expedition and get permission first (municipality, Hrvatske vode, the county nature-protection body — Natura Jadera for the Una — or the national park).
- Vrulje (submarine springs): Modrič (~2.9 km) and Zečica (1.2 km) near Rovanjska were explored by foreign teams with CCR and scooters, under a Croatian diving permit and with local cave divers; halocline, clay and 2–8 m visibility.
- Kornati NP: independent diving is banned; only with one of the 7 contracted centres (2026), in 9 zones, max -40 m, no night dives (19–07 h). Just Dive (Biograd) charges a €38 park surcharge.
Gases y carga
- Gas and CCR: trimix and O₂ at Kron Diving (Rab; rEvo training centre, full rebreather support), Kornati Diving Center (Sali, Dugi otok; booster), B-24 (Komiža, Vis; up to 300 bar, rental CCR ISC Megalodon/Pathfinder €80) and Just Dive (Biograd; O₂ and helium per 100 l). No fill station was found around Knin/Vrlika — bring your gas from the coast. In Split, LUK Technical Diving (Andrija Lukenda, +385 98 990 3231) teaches JJ-CCR and trimix; ask about fills.
Agua y temporada
- Water: springs 5–11 °C year-round (Kupa 5–7 °C, Cetina ~8 °C, Una avg 9.5 °C). Sea in the north (Istria) ~9 °C in April to ~20 °C in September; around Brač 17–27 °C. In vrulje cold fresh water (~9.5 °C) meets warm seawater (~21 °C).
Desplazamientos y alrededores
- Bases: Knin or Vrlika for the inland springs; an island base for the sea caves (Komiža for Biševo, Split for Šolta/Brač, Mali Lošinj or Zadar for Premuda and Dugi otok) — the islands are reached by ferry.
