The small hamlet of Tarnetar, about 75 kilometres from Rajkot is the site for one of Gujarat's most well known annual fairs, the Trinetreshwar Mahadev Fair popularly called the Tarnetar Mela. The Mela (fair) is held for three days in the period between August to September. Like all-important tribal fairs, it is attended by tribes from the adjoining areas of Koli, Bharwad, Rabari, Khant, Kanbi, Kathi, and Charan who indulge in dancing, competitive sports and other such forms of entertainment. There are over 300 stalls selling food, refreshments, exhibiting embroidery and cattle shows.

This fair is primarily a 'marriage mart' or 'Swayamvar' for the tribal youth of today who still visit Tarnetar, to find them a suitable bride. The tribal youth elegantly dressed in colourful dhotis, waistcoats and eye-catching turbans come to be chosen by village belles dressed in colourful finery.

The bachelors are usually identified by their large colourful embroidered umbrellas and their distinctive hairstyles. These umbrellas, which have become emblems of the fair, are embroidered by the tribal youth for over a year. The fair is held around the Trinetreshwar Temple dedicated to the three-eyed Lord Shiva, built at the beginning of the century. There is a kund (reservoir) here and it is popularly believed that a dip in its waters is as holy as a dip in the sacred River Ganges. The reservoir is also known as papanshu (the destroyer of sins).
