I am stuck trying to locate Caed Nua . I looked up a walkthrough and followed that . I am now in Black meadow  . I have cleared the area but cant seem to locate the path that leads to Caed Nua . I have tried all pathways and compass points but no new map comes up on the world map when I exit Black meadow . Am I missing some thing ?

it should be off the east exit: http://game-maps.com/PoE/img/Pillars-of-Eternity-World-Map.jpg

 

If you don't see it that may be a bug.  Did you rest at the Gilded Vale inn and speak to the ghost about being a Watcher?

You can rest anywhere, you still get the cutscene.

You have to talk with the animancer hanging from the in Gilded Vale after your first rest after reaching Gilded Vale.
