Legend
The Witch's Well of Tuhala

In the karst country of Tuhala, an underground river runs beneath the fields. After heavy rain or the spring thaw, water suddenly bursts up out of an old well and floods the meadow around it, as if the well were boiling. Local people said that this is when the witches are having their sauna underground and beating each other with birch whisks so hard that the water spills over. That is why the well is called Nõiakaev, the Witch's Well.

Eesti keeles
Tuhala karstialal voolab põldude all maa-alune jõgi. Pärast suurt vihma või kevadist sula purskub vesi äkki vanast kaevust välja ja ujutab ümbritseva heinamaa üle, otsekui kaev keeks. Kohalikud rääkisid, et siis teevad nõiad maa all sauna ja vihtlevad end kasevihtadega nii hoolega, et vesi üle ääre voolab. Sellepärast kutsutakse kaevu Nõiakaevuks.
