Mahasu Peak is named after Lord Mahasu, the main deity of the region. The site has a Durga Devi Temple, where a two-day festival is organised every year. The festival starts on the 3rd Tuesday of the month of May. The festival is popularly known as the Mahasu Jatara.It is believed that the temple was built by the Badoli Rulers in a village known as Chakroth. When the dynasty declined, the villagers shifted the idols of the temple to its present location and also started organising the annual fair. Archery competition, goat sacrifice and performances of folk songs and tribal dances, like Natti, are part of the celebration
