The favourite destination in the environs of Košice is undoubtedly Herľany. The special attraction of this former spa is the famous geyser of Herľany.
In the 1870s, an artesian well was drilled here in pursue of another mineral water source for the expanding spa. The 404.5 m deep probe brought up a strong spring of the mineral water. Now the periodicity of emanation is about 32-34 hours. The water springs for about 20-30 minutes to the height of maximum 20 metres. The yield of one eruption is about 600 hl of water.
As this unique natural scene occurs approximately every one and a half days, the tourist should enquire by phone at the local post office about the presumed time of its appearance.
