High Altitute Gamma Ray (HAGAR) experiment, an array of seven atmospheric Cherenkov telescopes, is installed at Hanle in Ladakh, at an altitude of 4300 m, in 2008. This experiment is designed to study very high energy gamma rays from astronomical sources. Taking advantage of high altitude location HAGAR has achieved energy threshold of about 200 GeV. Design details and performance parameters of HAGRA are discussed here. Also preliminary results for Crab nebula, which is a standard candle, are
