whats the safest leveling zone in northrend?

[fieryrainbow]

i dont want to deal with world pvp to the point that no life lvl 80s just camp quest hubs standing on top buildings so guards cant reach them one shotting people who just want to level, i spent about an hour dead while only playing for like 5mins cuz of the 2 min res timer.
so what is the least populated zones in northrend so i can quest in peace?

Go Howling Fjord, then Grizzly hills.
Do all quests and you will be lvl 80 by ignoring any other region
