This is the old Arathi Highlands map (pre BFA). At least 3 of the locations needed for the achievement are not on the new map.

All 11 of my toons over level 60 already had the Arathi Highlands exploration achievement and the 3 low levels that I took there couldn't even see the new map, so I don't know if this is like Silithus where discovering on the new map doesn't count toward the achievement or if you can discover the areas that are there on the new map. But you will need to discover at least 3 of the locations on the old map as they are not on the new map.
