Best way to display additional unloaded scene

So I have 2 large scenes which are separated by a large chasm. The user will have to jump across to change scenes. One scene is a desert and the other is a city. So in the desert I would like the Player to see the city but obviously I don’t want the city scene loaded yet, performance reasons. The only way I can think of showing the city is using impostors but I was just wondering if there might be another way.
