The old town of Tapolca, nestling behind Szent György-hegy, holds an extraordinary natural attraction: the Cave Lake. Hot karst water gouged out a labyrinth of winding corridors and halls in the limestone beneath the town, which were then flooded by crystal-clear groundwater. Rowing through the mysteriously lit, twisting waterway feels like being ferried across some mythological underworld — except there is a way back.
The cave is not only a tourist sight: its constant humid microclimate is ideal for the treatment of respiratory disorders, and a separate clinic at street level still offers the cave cure. Above ground, the Malom-tó — the central mill pond fed by the same karst springs — is the picturesque heart of the town.
