In ancient times when the main way of earning was hunting, these virgin forests were full of various types of preys.
And behold once experienced hunter shut with arrow to a young deer.
Injured deer began to flee with great efforts, gathering last the forces.
The hunter began to follow it promptly.
Hardly pulling its feet the deer reached the mineral sources of Jermuk, dumped into the water and what a magic! it got out from water fully healthy and recovered and immediately disappeared into the forest.
Experienced hunter astonished by the miracle of ordinary water and after that day the fame of "Jermuk" water disseminated all over the world, and the deer that showed the people the secret of miracle water become the favorite one for people and the symbol of Jermuk.
Arriving Jermuk and not seeing the big waterfall of "Jermuk" means not to be in "Jermuk".
This miracle of the nature which is pouring from over 70 meters height to Arpa Canyon and which looks like scattered hairs they have called "Mermaid's hair" (Djraharsi varser) and have composed the next legend.
From ancient time in the place of today's waterfall on top of the deep abyss there was a Castle of duke whose beautiful daughter was a part of virginal nature.
There came men from different places around the world to ask for princesse's hand, but she has rejected everybody, as her heart has belonged to the young and brave son of shepherd.
Every day after midnight, the young princess has throw the end of a long rope to the canyon from her bedroom's window, with which shepherd's son has climbed to his beloved one.
But the duke soon learned about it, has angered, irritated and has damned his doughter: that if she met the shepherd's son again let she would turn into mermaid and never get out from the water.
But the young lovers have been tempted to meet each other and then once again the beutiful princess to help her loved man for climbing the castle from the height of rock throwed her long and beutiful hairs instead of rope.
However, at the same moment came true the cruel damn of Duke and the Belle became a mermaid and her beautiful hairs, which were flowing into the canyon became a marvelous waterfall, and the people was called it the "mermaid's hairs".
