Miskolctapolca's Cave Bath is one of the most unusual thermal baths in Europe — a network of natural limestone caves filled with warm mineral water. You swim through dimly lit caverns with stalactites overhead, the water a constant 30°C year-round. There are outdoor pools too, and a bobsled track nearby for families. The complex has both indoor and outdoor sections, and family ticket prices keep it affordable.
