Super easy to get these. The first tour has you touring Alexandria as Amunet. Just follow the gold line on the ground and 8 stations later, you'll get this achievement. I should add, wait until you hear a clear note, which signifies the narrator is done with that segment, and you can move to the next. (If you look behind you, you should see check marks along the gold path you've followed. For faster completion, you can use a mount in some places.
Just make sure that, after the title screen, you select the Discovery tab, not your character tab.
