The Large Aperture GRB Observatory (LAGO) is aiming at the detection of the high  energy (around 100 GeV) component of Gamma Ray Bursts, using the single particle technique in arrays of Water Cherenkov Detectors (WCD) in high mountain sites (Chacaltaya, Bolivia, 5300 ma.s.l.; Pico Espejo, Venezuela, 4750 ma.s.l.; SierraNegra, Mexico, 4650 ma.s.l). WCD at high altitude offer a unique possibility of detecting low gamma fluxes in the 10 GeV-1TeV range. The status of the  Observatory and data collected from 2007 to date will bepresented.
