And a Tauren farm south of Ahn'Qiraj

Oh forgot to add this, you could try to get past the invisible wall with Far Sight, it's ideal for seeing hidden areas like Old Ironforge and Hyjal on live.

@Elmo:

Also there is a very large spooky cavern east of the Tauren settlement. It's empty, apart from all the bones lying around. And the Tauren place is abandoned.

Back in the day when I swam around Kalimdor that was by far the most spooky and atmospheric place.

My favorite part is the dwarven farms behind the airfield in Ironforge ... fantastic. Plus the gate to Oblivion. I'll never forget the day my level 23 dwarven priest and my buddy's level 40 mage discovered the airfield quite by accident. We then made the jump, saw the falls, the farms, the dwarven farmers, and finally made the fateful jump off the Oblivion gate (we just named it that for fun). That was a good day. Thinking of that day reminds me why I love this game so much.

What about the cave on the eastern rim of Dun Morogh that puts you in Silithus Chat? I've never been there, but it's apparently a copy of Ortell's Hideout in eastern Silithus.

All of these comments are completely irrelevant due to the fact a Semisonic song was linked in this article.

That is all.

My personal favorite, although it takes ALOT of work to get to, is the Goblin isle of Kezan/Undermine in live. It's south of Tanaris and can be seen on mapwow.com. It takes swim speed, hots, pots, water walking, sprint, etc. just to reach it but is so worth it. It's two islands with some random goblin buildings and a giant oil rig (this was back before the oil rig in IoQ so at the time it was a 100% unique model in the middle of nowhere serving no purpose)

@Elstor

It's used in the Scepter of Shifting Sands questline, like Isle of Dread and Alcaz Island. It's also much less work to get to than most of the places mentioned in this thread.

you can bypass invisible walls by destroying your hearthstone and then using the auto unstuck button, it port you forward a couple yards, past most walls, then you have to wait 5 minutes to do it again if theres another wall. course, unless you're a mage or a engineer, you're screwed without a hearth

Auto unstuck no longer works.

Bringing the option up on the PTR gives you two choices. Use your hearth, or teleport you to the graveyard. It no longer moves you forward.
