This is a very fustrating way to get into Hyjal in the new patch but once you do it the first time its easy after that
First you need to get to the portal in Darkwhisper Gorge.
Once your there get over to the pillar here

Now make your way around to the other side of the pillar and start

Once you do that you should see a opening jus ahead

Now thats the easy part done, Next go up as far as you can it should be here somewhere

Now that your there you have to wall jump up at least 3 times and it should bring you about here (Depending on how and where you jump) This might and probally will take a few attempts.

When eventually you get to that point, Jus jump across to the rock edge

Once you get there continue up to the top, It may take a few attempts but you know your safe when your here

Go to the top of the mountain and get to here

You could just jump down from there but there a huge invisble wall, So now how to get past it. Advance to here

Get 1 and then jump across to 2 (It makes sense once you look at the pic)

When you get to 2 just jump up to here

Continue going up till you get to bout here

Again jus continue up to here

Then jus jump and and down

That fall may take a cause a bit of damage depending on your class and level but usually wouldnt kill you.
After you get down jus continue to the path, and there ye go, Yet another way to Hyjal in 2.0.1
This is my first Pic guide so be gentle
