Romania – Cave diving & karst springs

Romania's cave diving happens in a handful of deep karst resurgences, most of them in the Apuseni Mountains. Around Gârda de Sus and Arieșeni the Tăuz spring, the terminal sump of Coiba Mare and the Cotețul Dobreștilor spring have drawn Polish, Czech, Swiss and Finnish expeditions since the 1980s, with depths of 76–92 m and several fatalities. In the Pădurea Craiului the Izbândiș spring holds the national record of 129 m (2024, Salvamont Cluj divers), and in Mehedinți the Izverna cave has a chain of sumps, the longest over 400 m. These are exploration dives in 4–9 °C water, often with near-zero visibility after rain. Speleological diving needs authorisation from the Speleological Heritage Commission, and no commercial operator offers guided dives here.

Facts

• Cave diving needs CPS authorisation: The Ministry of Environment's list of cave activities approved by the Speleological Heritage Commission (CPS) includes 'exploring flooded galleries – speleological dives by specialised teams with specific techniques and equipment'. CPS authorisations name the caves, the number of entries and of persons, and closed periods (e.g. no access during bat hibernation, 1 December – 31 March, in some caves). (source: mmediu.ro)
• National cave-diving record: In February 2024 Salvamont Cluj divers Cristian Irimieș and Flaviu Pop, supported by Ciprian Man, reached 129 m in the Izbândiș spring, beating the 121 m record set there in 2022; the water is no more than 9 °C and 425 m of guideline is fixed at 86 points.

• Visibility depends on rain: During the September 2016 Gârda–Arieșeni camp the team checked the Tăuz spring daily but visibility never rose above 0.5 m, so it could not be dived; in Coiba Mare floods had jammed logs into the terminal sump. (source: alba24.ro)
• Emergency: Call 112. Cave rescue in Romania is run by the Salvaspeo / Salvamont services; the Cluj Salvamont-Salvaspeo unit has its own cave-diving team (the divers who set the Izbândiș record). (source: actualdecluj.ro)

Season

• Best months: Aug, Sep, Oct
• Acceptable: Jan, Feb, Mar, Jul, Nov, Dec
• Poor: Apr, May, Jun
• Water temperature: 4–9 °C

Karst spring water is cold all year (Tăuz 4–6 C, Izbândiș at most 9 C). Expeditions mostly run in late summer and autumn; the record dive was in February. After snowmelt and heavy rain the springs flood and turn murky, with visibility below 0.5 m. Month ratings are estimated from expedition practice.

These are deep, cold exploration cave dives, not recreational sites: several divers have died in them. They need full cave training, trimix-level gas planning, a permit and a team that knows the system. Positions mark the spring or cave entrance for orientation only.
