Grates Cove was first settled in 1790 by four families from Lower Island Cove and one family from Old Perlican. It is believed that Grates Cove was visited by seasonal fisherman before this and some have expressed the belief that it was visited as early as 1497 by John Cabot. This speculation has been fueled by the presence of a large rock high above the water on a cliff face located in Grates Cove. As Harold Horwood states, "some of those who formerly examined it, including a curator of the Newfoundland Museum, professed to be able to read the names IO CABOTO, SANCIUS and SAINMALIA quite plainly."
