Before the Griffons were farmed out of existence I found time to visit both the Griffons outside of Augory Rock and the Trolls outside of Droknars forge. The hope at the time was that alternating runs would minimise the chance of any anti farming code providing lessened drop quality. To be honest I couldn't tell you if that worked but I got to kill stuff.
To get to the Trolls just take the Northern exit from Droknars Forge and proceed to the cave on the left hand side. A couple of months back there was barely anyone doing it (although the 168xp per kill almost makes it worth it for accumulating skill points) but now you could just follow the Monk/Elementalists out of the door. The path is shown here:
The following screenshot showed a conservative build that was used to solo the trolls (see the W/Mo Griffon farming post in builds and templates as I used the same for both):
