I have completed One Small Favour quest but I can't travel to the feldip hills, I get a message which says i can't travel there at the moment.

There may be a quest you need to do. I vaguely remember making some crystal lights on a landing patch. But then again, you might have to fly to the Grand Tree then to the hills.

I need to fly to the grand tree first then i can fly to any of the locations.

 

Thanks for the help.

The quest needed to fly to Feldip Hills by gnome glider is One small favour.  =]
