for me personally its all of black temple, but specifically the outdoor hallways/corridors its been awhile and dont really care to check but its only because it was my first raid and i was mindfucked throughout the whole thing.
when i still played i would sometimes go to outland and fly around the whole continent ending up at nagrand when it was either dawn or dusk and set up camp on this specific floating island near the northern zone entrance/exit and just take it all in. oddly enough the close second(or should i say third in this case) would have to blade's edge, something about that zone and questing in it(yeh i know) is just so unique. It simply had the best atmosphere to look at unless u were high and in zangermarsh
WoW got it right with great zones especially the scale of them(scaled great as u gained access to mounts/flying mounts)

Falling off the branches on Teldrassil was a pretty epic place/moment when I first started. Other then that I have always loved Moonglade and the Isle of Quel'Danas as epic places go... not to mention the elite areas of Shadowmoon.
