WOW moments in WoW

Have you had any moments, where you came around (in game) a corner and just went WOW! Have you been so incredibly impressed by something the art department came up with that you just couldn't express it?

I have had a few, where I just thought the game was so impressive that it might just compare to real life beauty. The most memorable for me so far was coming over the hill from Zangarmarsh into Nagrand. The sky and the mountains, the floating islands and the clouds, the moons, just totally overawed me. They really did a good job on that zone, bot art and implementation.
