We don't have any records of ancient Greeks ever trying to climb Mt. Olympus, and if they had, they would not have expected to meet the gods there in the first place (making the endeavour fruitless in the first place). In a similar thread a couple of years ago u/CommanderRown quotes from "Classical Myth," by Barry B. Powell to illustrate the point that there was an understanding that the physical place Mt. Olympus and the mystical home of the gods exsisted in different spheres:

Another element of my is setting. The setting is the time and place in which the action of the story unfolds. Myths are never set in the present or the recent past, the action always takes place in the distant past or in a shadowy time altogether outside human chronology. The setting of myths may be in an actual city, such as Athens or Thebes, or some other location familiar to the audience. In other myths, the setting is an obscure place: the underworld, which no one in the real world every visited; Mount Olympus, which really exists but in myth is the home of the gods; or Crete of a very long time ago.
