Things to do · Destination Guide
Thermal cave passages and flooded industrial halls beneath Budapest, for divers with the right training.
Pick an activity mode to compare signature sites, skill fit, and gear planning notes before you lock your trip.
From the Molnar Janos Cave Diving Center at Frankel Leo utca to the industrial flooded rooms of Kobanya Mine, Budapest offers controlled, guided, land-based overhead diving. The thermal cave and colder mine are physically separate venues with different training, gas and equipment demands. A limited supervised intro or open-water zone does not confer access to the main cave systems.
Molnar Janos Cave
Thermal-water limestone cave below Buda, with protected habitat, operator-led cave routes and a separately screened introductory product.
Kobanya Mine
Flooded former industrial cellars in eastern Budapest, with limited non-overhead access and separate, qualification-controlled mine overhead routes.
Operator Checklist
Contact the specific operator in writing with exact certifications, documented cave/technical experience, logbook, requested route, medical certificate, insurance covering overhead dives, suit qualification, cylinder/gas setup, and preferred dates. The MJ Cave 2016 rules remain publicly accessible, but confirm which edition applies to your booked dive. The operator may decline a route, equipment or participant. Never treat a guide as a substitute for the required training. Contact; rules.
