Why come here
In Budapest you dive in the middle of the city: the Molnár János cave is an active thermal cave under the Rózsadomb, with its entrance by the Lukács baths, ~200 m from the Danube. Down to -10 m the water is 28 °C all year and deeper ~18–20 °C, crystal-clear with very little flow, to ~-100 m. You dive it only with a guide from MJ Cave, the only licensed operator, and bring your certification cards, cave-diving insurance and a medical certificate; outside zone 1 a drysuit is mandatory. Under Kőbánya there are also the flooded wells of an old quarry and beer cellars, in water of 8–14 °C: the Park well is open to open water divers, the other three need a cave card.
Don't miss
- Molnár János-barlang: warm, crystal-clear karst water with rock and crystal formations, blind amphipods and fossils such as shark teeth, under a hill in the city.
- Kőbányai pincerendszer: vaults, corridors, wrought-iron spiral staircases and old brewery installations in the four flooded wells of a former brewery.
On a rest day
- Lukács Baths: The thermal bath next to the cave in Buda, with pools and saunas, fed by the same warm water you dive in.
- Buda Castle Quarter: Walk through the castle and the old quarter above the Danube, with views over the river banks.
- Pál-völgyi Cave: A dry dripstone cave in Budapest, the longest cave in Hungary, with a tour over more than 400 steps and a ladder past calcite crystals.
- Tapolca Lake Cave: Take a small boat over the lit, bluish water of an underground lake beneath the streets of Tapolca, near Lake Balaton.
