Grimbeorn has refused to reopen the trade-routes with the Elves of Felegoth.
'I know that Thranduil wishes me to reopen the trade route into Mirkwood. I have heard of the hardships faced by the Dwarves of the Lonely Mountain and the refugees from out of the East, but my own family must come first. Go to the Forest Gate and tell the Elves there what I have decided.'
The Forest Gate can be found at the eastern edge of the Beorning-lands where the Vale of Anduin meets Eryn Lasgalen.
You should travel to the Forest Gate and tell the Wood-elves of Grimbeorn's decision.
Legolas can be found at the Forest Gate at the eastern edge of the Beorning-lands.
