Easy instructions:
1. Hoardale is in the center of the zone and contains the Tol Ascarnen (16.6s, 17.2w) location.
2. East of Hoardale is Tirith Rhaw (17.5s, 14.5w) almost straight North of Glan Vraig just above Coldfells.
3. South of Hoardale near the center of the Hithlad forest is Grimwood Lumber-camp (19.3s, 17.6w), which is West of Glan Vraig not South as described above.
4. North-West of Hoardale and Glan Vraig (also not the South) and far above Hoarwell is Lugazag (15.4s, 19.7w).
5. Far North and East of Hoardale is the Isendeep Mine (12.5s, 15.0w). Take the right path at Arador's End (above the E) and just inside the tunnel to complete.
Note: Be careful around these areas, there is like a faction war of some kind and I walked almost to the center of Lugazag before things started spawning on me. You can look on your map to see if the flag is red or blue, if its blue you are safe, but you really dont have to get very close before getting the discovery message. If you die you will get the message that it effects your PVP rating. Also, there are mobs that have yellow names that say "...level 50". This one named wolf kept up with my horse and followed me 3 times the distance of any normal mob before turning away. As a relief though all of the bears here are friendly.
