The manifestation of lord Vyadeshwar at Guhagar,the devotee who worshipped him at first and the reason he was named Vyadeshwar,is a long mystic story.
Parshuram the sixth incarnation of god Vishnu,was a great devotee of lord Shiva.By pushing back the western sea with his energetic arrow, he created Konkan region. One day after a holy- bath in western sea, Parshuram prayed lord shiva to bless him by his presence and dwell perpetually in this region.Thus pleased by his piety lord Shiva blessed him by his appearance and granted him, his wishes will be fulfilled and he will bless Parshuram every early morning by his presence and will dwell in this region, until the dooms-day.
In this Parshuram bhumi their were many Brahmin seers.Among them was a bright monk Vyadey, who had a desire to see lord Shiva.So by the grant of Parshuram,Vyadey built an monastery at sea-shore and resided there, worshipping Shiva.Knowing the motive of lord Parshuram,he established a Shiv-ling.Lord Shiva himself in the form of Shiv-ling resided in the place.As the Shiv-ling was established by Vyadey,it was named after him as Vyadeshwar.This lord Vyadeshwar is perennial awaken to fulfill all the desires of his devotees in ‘Guharanya’ which means ‘Guhagar’.
There is an another story of the holy place Vyadeshwar.
After the beginning of Kaliyug a king named Shalivahan ruled over.The story begins 20 years after his death.The place where Shiv-ling of lord Vyadeshwar was established and where Parshuram resided in an invisible form (gudh-rup) was called ‘Gudh-desh’.
In this Gudh-desh ruled the king named ‘Sakoram’.
In his era the Vyadeshwar-ling was surrounded by islands of bamboo.There was a stable nearby where Vyadeshwar approaches today and some cows to feed milk.Among those cows their was a reddish cow named Kapila.The cow-herd used to leave cows for grazing in forest.The cow Kapila daily while grazing,used to pour the milk from her teat at a certain place.The owner had a doubt on the cow-herd of stealing the milk.
On knowing it the cow-herd got angry and decided to detect the truth.He kept an eye on the movements of cows and recognized Kapila daily pouring her milk on a certain rock.In anger he beat the cow harshly.But suddenly a miracle happened as blood started flowing from the rock.The threatened cow-herd published this incident all over.When this news reached to the king Sakoram,he immediately visited the place and saw the miracle.He ordered his men to dig out the rock.But his men were unable as they could not find the base of rock.Later everyone recognized that it was a Shiv-ling and was unshakeable as Meru-parvat.
King Sakoram thought,in this Kaliyug the invisible god Shiva himself has arrived in the form of Shiv-ling.At the same night lord Shankar appeared in the dream of king and stated him that as the Shiv-ling has approached in front of the wada (stable),so the Shiv-ling must be named as Vyadeshwar.

The king with ecstacy built a large temple of deity Vyadeshwar.
Still today lord shankar invisibely dwells here and showers blessings on his devotees.
