On map two, towards the left side, "Sea of Núrnen", where the second half of the story takes place, is a good location to try and achieve this trophy. To easily get the The White Rider Trophy/Achievement you need the Shadow Mount ability.
Your starting point for getting the The White Rider Trophy/Achievement is Forge Tower in the south-west, fast travel to it. Another interesting things to keep in mind is making sure that you try to get this task done during Day time in your game.
The locations of Slaves will change at night. If you are at Night in your game, just try to advance the time by scrolling over a Forge Tower on your map. A couple of Uruks will be guarding the slaves, get rid of the Uruks and free the slaves.
