Hungary – Lakes & Training Sites
Most Hungarian divers train and keep in practice in a handful of managed lakes. The Kotró gravel-pit lake at Gyékényes near the Drava has a year-round dive base with sunken cars and boats. The Palatinus Lake at Dorog has training platforms, a rope trail and a small underwater museum. In Tata, the Fényes springs keep their lakes at 18–25 °C even in winter and can be visited on guided dives. Visibility is modest (a few metres) and pike, zander, catfish and crayfish are common. On navigable waters and in harbours, including Lake Balaton, diving without a permit is restricted, and in most quarry lakes swimming and diving are banned. Dive only at sites with an operator or a written permission.
Facts
- Diving near navigation (Hungary): Under the Hungarian Navigation Rules (57/2011. (XI. 22.) NFM decree, art. 6.37), diving without special permission is prohibited where it may obstruct navigation: fairways, usual vessel routes, harbours and harbour entrances, mooring places and water-ski areas. (source: net.jogtar.hu)
- Dive flag: A vessel supporting diving work must show a rigid replica of code flag 'A' at least 1 m high, visible from all sides day and night (art. 3.36). Vessels near diving work must slow to minimum speed and keep at least 50 m from the signal (art. 4.10). (source: net.jogtar.hu)
- Harbours on Lake Balaton: Harbour rules prohibit unauthorised scuba diving in harbour waters (e.g. Siófok harbour rules, point 4.4.10). (source: bahart.hu)
- Balaton visibility: Balaton is shallow and silty, so visibility is usually very poor: a national-park survey dive off the west side of Tihany in December 2024 measured 4 °C at 2.2 m and about 10 cm visibility; a club dive in April 2019 had about 50 cm at 11 °C. There is no established recreational dive site on the lake. (source: bfnp.hu, borntodive.eu)
- Emergency: Call 112. For diving accidents, DAN Europe members can also call the DAN Europe international hotline (+39 06 4211 5685 – check the number on your card). (source: daneurope.org)
- Recompression chamber: The Hyperbaric Oxygen Therapy Centre of Vaszary Kolos Hospital, Esztergom (Petőfi Sándor u. 26-28, +36 33 542 387) describes itself as Hungary's only hospital hyperbaric centre and lists diving accidents (DCI) and gas embolism as urgent indications. 24/7 availability is not stated – check current status. (source: vaszary.hu)
- Dive rules at bases: Hungarian bases apply the Hungarian Diving Federation (MBSZ) dive rules. At Gyékényes, unguided diving requires at least an advanced certification; open-water-level divers may dive only with a guide after a check dive. (source: meruljvelem.hu)
- Quarry-lake safety: Of nearly forty quarry lakes in Pest County, bathing is permitted at only nine; quarry lakes typically drop off suddenly after a few steps and the cold deeper water can cause shock or cramps. Dive only at operated bases. (source: perbal.hu)
- Season & water temperature: Gravel-pit lakes are dived all year (Gyékényes base open year-round); surface water exceeds 20 °C in summer (Dorog), while the Tata springs stay around 18–25 °C even in winter. Check current conditions. (source: meruljvelem.hu, horizondive.hu, aquanauta.hu)
- Freshwater jellyfish: Freshwater jellyfish occur in the Dorog (reported since 2015) and Gyékényes lakes; they are harmless to divers. (source: titanbuvar.hu, meruljvelem.hu)
- Dorog water level 2025: In August 2025 Lake Palatinus was about 80–100 cm below its optimal level due to drought; the deeper parts were reported unaffected. Check current status. (source: telex.hu)
Season
- Best months: May, Jun, Sep, Oct
- Acceptable: Apr, Jul, Aug, Nov
- Poor: Dec, Jan, Feb, Mar
- Water temperature: 2–27 °C
Balaton and the quarry/gravel lakes: water is 23–26 C in August and 2–5 C in winter. Summer algal blooms and boat traffic hurt visibility; spring and autumn are clearer. The Balaton is shallow with modest visibility; ice diving is possible in hard winters. No dive-specific source was found.

Entry fees, registration rules and opening hours change; check them with the base before you go. Lakes are cold below the summer thermocline, so plan exposure protection accordingly. Positions are for orientation only.
