Where can I find the skydragon? 

First playthrough and I got to the end - never found it. 
Now on my second playthrough Im at act 3 (start). Been looking all over still cant find it.
 

Its seemingly extremely hard to find! Do you need a certain quest to unlock the zone?

It's harassing the Temple of Hylea and it is the task she gives for you to solve. I think you can do it even without her help if you talk with the priests at Oldsong or if you simply go there.

 

There's a path leading up through the Oldsong district to a forest, and there the entrance to the temple is in the north west.

It can be accessed from Northweald; there's an area called Pilgrim's Rest with a climb nearby. Pray to Hylea at the Twin Elms temple and she'll show you a vision of her temple being attacked by a dragon. Alternatively, talk to her priests in the Oldsong district and they'll send you to the same place.
