Gravel has to be put on an engineered base that will support it or it just sinks into the ground.
Any area with pressure on it (horses, cars, elephants) winds up being 'built like a road' or it just sinks away and disappears.
Generally the engineered base needs to be big rock, but it needs to be placed on subsoil, not topsoil. So you scrape away the topsoil to undisturbed sub base, put down big rock, then gravel, then that's going to stay there.
