Kolayat Fair is the largest cattle fair of Bikaner district in Rajasthan. People from far and wide come to trade buffaloes, horses, camels and cattle. Apart from this, a large number of pilgrims also arrive in the district to visit town's lake for spiritual purposes. Although people visit this holy lake throughout the year, but the most auspicious occasion is Kartika Poornima, the full-moon day of the Kolayat Fair. There are several temples near the lake and the most famous one is dedicated to the sage Kapil Muni.
