Gigas spawn at three locations on the Ragnarok map of Ark Survival Evolved. If you are looking to tame a giga, or avoid building a base where they spawn here are the locations. Often there will be only one or two Giganotosaurus on the map at any one time, sometimes there will be two in one of the spawns.
